Abstract

A textile substrate (1A) includes a warp and a weft and containing several different disposable and/or usable materials. A first subset of the totality of all warp threads and weft threads contains one or more warp threads (K1(1), K2(1), K3(1)) and one or more weft threads (S1(1)), wherein each warp thread of the first subset and each weft thread of the first subset is made of a first of the different disposable materials. A second subset of the totality of all warp threads (K1(2), K2(2), K3(2)) and weft threads contains one or more warp threads and/or one or more weft threads, wherein each warp thread of the second subset and each weft thread of the second subset is made of a second of the different disposable materials. A third subset of the totality of all warp threads and weft threads contains one or more warp threads and/or one or more weft threads (S1(3)), wherein each warp thread of the third subset and each weft thread of the third subset is made of a material (Z) that can be destroyed by means of a chemical and/or physical method. The warp threads and weft threads of the first and second subsets (K1 (I), K2(1), K3(1), K1(2), K2(2), K3(2)) are arranged in such a way that said warp threads and weft threads are not bound to one another and thus can be separated if the respective warp threads and/or weft threads (S1(3)) of the third subset are destroyed.

(18) FIG. 12C shows a detail of the seventh embodiment according to FIG. 12B.

(19) FIG. 1 shows a perspective view of a textile substrate 1 according to the invention in the form of a woven fabric which in the present example extends parallel to a plane. The textile substrate 1 in this case forms a flat layer having the thickness d and has a first surface O1 and a second surface O2 opposite the first surface O1.

(20) FIGS. 3-12 show various embodiments of the textile substrate 1, where these embodiments are subsequently designed with the reference numbers 1A-1G. The specific details shown in FIGS. 3-12 are achieved in at least one region of the respective textile substrate 1A-1G. This at least one region is subsequently designated by 1-1. With a view to the invention it should be noted that the region 1-1 can be merely a part of the textile substrate as shown schematically in FIG. 1 for example (the dot-dash line in FIG. 1 marks an outer edge of the region 1-1). In this case the details shown in FIGS. 3-12 need not necessarily be achieved outside the region 1-1. Within the framework of the invention, however, it is also feasible that the region 1-1 is identical to the textile substrate itself. In this case, the details shown in FIGS. 3-12 would be representative for the entire textile substrate.

(21) In the following it is assumed that the textile substrate 1A-1G contains at least two (in the case of the textile substrates 1F and 1G at least three) variously disposable and/or utilisable materials or a plurality of variously disposable and/or utilisable materials selected from at least two (in the case of the textile substrate 1F and 1G from at least three) different utilisation groups. Examples for such materials or utilisation groups can be deduced from Table 1.

(22) In the following it is assumed that the textile substrates 1A-1G are each composed of a warp comprising a plurality of warp threads and a weft comprising a plurality of weft threads, where each warp thread crosses over a plurality of weft threads and each weft thread crosses over a plurality of warp threads so that the warp and the weft jointly form a layer having (the surface O1 and O2). The textile substrates 1A-1G are all executed as textile substrate according to variant 1 of the invention.

(23) In the following it is further assumed that the entirety of all the warp threads and weft threads of each textile substrate 1A-1G comprises three or more subsets (each containing warp and/or weft threads), which differ in that the warp or weft threads belonging to different subsets consist of different materials. In order to be able to distinguish the individual warp threads and weft threads of the respective textile substrate, the following nomenclature is used to designate the warp threads and weft threads: each warp thread of a textile substrate is subsequently identified with the designation Ki(j) and each weft thread is identified with the designation Si(j). Here j is in each case a natural number which characterised the respective subset and therefore the material of the respective warp thread or weft thread. Furthermore i is a natural number which serves to characterise warp threads or weft threads which belong to the same subset.

(24) Subsequently Ki(1) or Si(1) designates a warp thread or weft thread which belongs to a first subset of the entirety of all the warp threads and weft threads. This subset comprises warp threads or weft threads where the respective warp thread or weft thread consists of a first one of the variously disposable and/or utilisable materials or from a first one of the disposable and/or utilisable materials selected from the various utilisation groups.

(25) Accordingly Ki(2) or Si(2) designates a warp thread or weft thread which belongs to a second subset of the entirety of all the warp threads and weft threads. This subset comprises warp threads or weft threads where the respective warp thread or weft thread consists of respectively a second one of the variously disposable and/or utilisable materials or from one of a second of the disposable and/or utilisable materials selected from the various utilisation groups.

(26) Ki(3) or Si(3) subsequently designates a warp thread or weft thread which belongs to a third subset of the entirety of all the warp threads and weft threads. This subset comprises warp threads or weft threads which are essential to the invention, which consists of a destructible material and which can be destroyed by means of a suitable chemical and/or physical method.

(27) In connection with textile substrate 1F according to FIG. 11B and textile substrate 1G according to FIG. 12B, Ki(4) or Si(4) subsequently designates a warp thread or weft thread which belongs to a fourth subset of the entirety of all the warp threads and weft threads. This subset comprises warp threads or weft threads where the respective warp thread or weft thread consists of a third one of the variously disposable and/or utilisable materials or from one of a third one of the disposable and/or utilisable materials selected from the various utilisation groups.

(28) FIG. 2A shows as a simple exemplary embodiment of the invention, an arrangement of three warp threads and two weft threads consisting of warp threads K1(1) and K2(1) of the first subset, one weft thread S1(1) of the first subset, one warp thread K1(2) of the second subset and one (destructible) weft thread S1(3) of the third subset. In this arrangement, the respective warp threads K1(1) and K2(1) cross over the weft thread S1(1) on one (same) side, the warp thread K1(2) crosses over the weft thread S(1) on the side opposite the warp threads K1(1) and K2(1). In this example, all the warp threads of the first subset (K1(1) and K2(1)) are separated from the respective warp threads of the second subset (K1(2)) by the weft thread S1(1) of the first subset (as can be seen in particular from FIGS. 2B and 2C). The (destructible) weft thread S1(3) of the third subset is arranged in such a manner that it crosses over the warp threads K1(1) and K2(1) of the first subset on a side facing away from the warp thread K1(2) of the second subset and crosses over the warp thread K1(2) of the second subset on the side facing away from the warp threads K1(1) and K2(1) of the first subset. In this way, the warp thread K1(2) of the second subset is bound to the weft thread S1(1) and the warp threads K1(1) and K2(1) of the first subset. In this situation the warp threads K1(2), K1(1) and K2(1) cannot be separated from one another. If the (destructible) weft thread S1(3) of the third subset according to the invention is destroyed by means of a suitable chemical and/or physical method, the warp thread K1(2) of the second subset is no longer bound to the weft thread S1(1) and the warp threads K1(1) and K2(1) of the first subset. In this situation, the warp thread K1(2) of the second subset is effectively separated from the warp threads K1(1) and K2(1) by the weft thread S1(1) of the first subset, especially as the weft thread S1(1) crosses over the warp threads K1(1), K2(1) and K1(2) at an angle of 90 and is arranged between the warp threads of the first subset (K1(1) and K2(1)) and the warp thread K1(2) of the second subset. On account of this separating effect of the weft thread S1(1), the warp threads of the first subset (K1(1) and K2(1)) can now be separated in a simple manner from the warp thread K1(2) of the second subset.

(29) FIG. 3 shows a region 1-1 of a textile substrate 1A according to the invention in a woven-fabric sectional view (in a section perpendicular to the respective warp threads). Through the region 1-1 there extends three warp threads K1(1), K2(1), K3(1) of the first subset, at least one weft thread S1(1) of the first subset (and possibly further weft threads of the first subset which extend parallel to the weft thread S1(1) and would have the same profile as the weft threads S1(1) in the diagram according to FIG. 3), three warp threads K1(2), K2(2), K3(2) of the second subset. and at least one weft thread S1(3) of the third subset (and possibly further weft threads of the third subset which extend parallel to the weft thread S1(3) and would have the same profile as the weft threads S1(3) in the diagram according to FIG. 3).

(30) In the case of the textile substrate 1A, in the region 1-1 each of the warp threads K1(1), K2(1), K3(1) of the first subset crosses over the weft thread S1(1) of the first subset on a side facing the second surface O2. Furthermore, the three warp threads K1(2), K2(2), K3(2) of the second subset cross over the weft thread S1(1) on a side facing the first surface O1. Accordingly in the region 1-1 all the warp threads K1(1), K2(1), K3(1) of the first subset are separated from the warp threads K1(2), K2(2), K3(2) of the second subset by means of the weft thread S1(1) of the first subset. The at least one weft thread S1(3) of the third subset crosses over all the warp threads K1(1), K2(1), K3(1) of the first subset which extend through the region 1-1 on a side facing the second surface O2 and crosses over all the warp threads K1(2), K2(2), K3(2) of the second subset extending through the region 1-1 on a side facing the first surface O1. In this way all the warp threads extending through the region 1-1 are bound by the weft thread S1(1) of the first subset and the weft thread S1(3) of the third subset so that the textile substrate 1A forms a stable layer in the region 1-1. However, if the weft thread S1(3) of the third subset is destroyed according to the invention by means of a suitable chemical and/or physical method, the warp threads K1(1), K2(1), K3(1) of the first subset, warp threads K1(2), K2(2), K3(2) of the second subset and the weft thread S1(1) of the first subset are no longer bound to one another in the region 1-1. As a result of the destruction of the weft thread S1(3) of the third subset, the textile substrate 1A is decomposed into individual warp threads K1(1), K2(1), K3(1), K1(2), K2(2), K3(2) lying loosely next to one another or above one another and the weft thread S1(3).

(31) In this situation, the warp threads K1(2), K2(2), K3(2) of the second subset are effectively separated from the warp threads K1(1), K2(1), K3(1) of the first subset by the weft thread S1(1) of the first subset, especially as the weft thread S1(1) crosses over the warp threads K1(2), K2(2), K3(2), K1(1), K2(1), K3(1) at an angle of 90 and lies between the warp threads of the first subset K1(1), K2(1), K3(1) and the warp threads K1(2), K2(2), K3(2) of the second subset. On account of this separating effect of the weft thread S1(1), the warp threads of the first subset can now be separated in a simple manner from the warp threads of the second subset.

(32) FIG. 4 shows a region 1-1 of a textile substrate 1B according to the invention in a woven-fabric sectional view (in a section perpendicular to the respective warp threads). Through the region 1-1 there extends six warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset, at least one weft thread S1(1) of the first subset (and possibly further weft threads of the first subset which extend parallel to the weft thread S1(1) and would have the same profile as the weft threads S1(1) in the diagram according to FIG. 4), six warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) of the second subset, at least one weft thread S1(2) of the second subset (and possibly further weft threads of the second subset which extend parallel to the weft thread S1(2) and would have the same profile as the weft thread S1(2) in the diagram according to FIG. 4), at least one weft thread S1(3) of the third subset (and possibly further weft threads of the third subset which extend parallel to the weft thread S1(3) and would have the same profile as the weft thread S1(3) in the diagram according to FIG. 4).

(33) In the case of the textile substrate 1B, in the region 1-1 each of the weft thread S1(1) of the first subset crosses over all the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset extending through the region 1-1 on a side facing the first surface O1 and crosses over all the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) of the second subset extending through the region 1-1 on a side facing the second surface O2 and consequently brings about a spatial separation between the warp threads of the first subset and the warp threads of the second subset.

(34) The weft thread S1(2) of the second subset crosses over alternately all the warp threads of the second subset extending through the region 1-1 so that the weft thread S1(2) crosses over the warp threads K2(2), K4(2) and K6(23) on a side facing the first surface O1 and crosses over the warp threads K1(2), K3(2) and K5(2) on a side facing the second surface O2. Furthermore, the weft thread S1(2) of the second subset crosses over the warp threads of the first subset extending through the region 1-1 on a side facing the first surface O1. Consequently the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset and the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) of the second subset are not bound to one another by the weft threads S1(1) and S1(2) of the first and second subset.

(35) In the example, the weft thread S1(3) of the third subset extends through the region 1-1 in such a manner that it crosses over all the warp threads of the first subset extending through the region 1-1 on a side facing the second surface O2 and additionally crosses over the warp threads K1(2), K3(2), K4(2), K5(2), K6(2) of the second subset on a side facing the first surface O1. The warp thread K2(2) on the other hand is crossed over by the weft thread S1(3) on a side facing the second surface O2. This arrangement of the weft thread S1(3) of the third subset has the effect in the present case that the warp threads and weft threads of the first and second subset extending through the region 1-1 are bound to one another in the region 1-1 and form a stable layer as long as the weft thread S1(3) is not destroyed.

(36) If in the case of textile substrate B, the weft thread S1(3) of the third subset is destroyed according to the invention by applying a suitable chemical and/or physical method, the warp threads and weft threads of the first subset can then be separated in a simple manner from the warp threads and weft threads of the second subset. This is particularly apparent from FIG. 8. The upper part of FIG. 8 shows the textile substrate in a state in which the weft thread S1(3) of the third subset is intact (according to the woven-fabric sectional view according to FIG. 4). The lower part of FIG. 8 shows the relative arrangement of the warp threads and weft threads of the first and second subset extending through the region 1-1 for the case that the weft thread S1(3) in the textile substrate 1B is destroyed and is completely removed (in a sectional view similar to the woven-fabric sectional view according to FIG. 4). As can be seen, after destruction of the warp thread S1(3) the warp threads and weft threads of the first and second subset extending through the region 1-1 are arranged in a plurality of layers L1-L5 which follow one another spatially and which are separated from one another. Here the warp threads K1(2), K3(2) and K5(2) of the second subset form the first layer L1, the weft thread S1(2) of the second subset forms a second layer L2, the warp threads K2(2), K4(2) and K6(2) of the second subset form a third layer L3, the weft thread S1(1) of the first subset forms a fourth layer L4, the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset form a fifth layer L5. As can be seen, the warp threads pertaining to the layer L1 are spatially separated from the warp threads L3 pertaining to the layer L3 by the weft thread S1(2) pertaining to the layer L2. In this case, the weft thread S1(2) crosses the warp threads pertaining to the layer L1 and the warp threads L3 pertaining to the layer L3 in each case at an angle of 90 but does not bind these warp threads to one another. Furthermore, the warp threads pertaining to the layer L3 are spatially separated from the warp threads pertaining to the layer L5 by the weft thread S1(1) pertaining to the layer L4. In this case, the weft thread S1(1) crosses the warp threads pertaining to the layer L3 and the warp threads L3 pertaining to the layer L5 in each case at an angle of 90 but does not bind these warp threads to one another. Accordingly, the warp threads or weft threads pertaining to the respective layers L1-L5 form an arrangement of crossing threads which lie individually loosely above one another or next to one another and can be individually separated from one another. In this case, it is helpful that the warp threads or weft threads of neighbouring layers each cross at an angle of 90. Thus, the warp threads and weft threads can preferably be separated in layers (in the sequence of layers L1-L5 successively).

(37) FIG. 5 shows a region 1-1 of a textile substrate 1C according to the invention in a woven-fabric sectional view (in a section perpendicular to the respective warp threads). Through the region 1-1 there extends six warp threads K1 (1), K2 (1), K3 (1), K4(1), K5(1), K6(1) of the first subset, at least two weft threads S1(1) and S2(1) of the first subset (and possibly further weft threads of the first subset which extend parallel to one of the weft threads S1(1) or S2(1) and would have the same profile as the respective weft thread S1(1) or S2(1) in the diagram according to FIG. 5), five warp threads K1(2), K2(2), K3(2), K4(2), K5(2), of the second subset, at least one weft thread S1(3) of the third subset (and possibly further weft threads of the third subset which extend parallel to the weft thread S1(3) and would have the same profile as the weft thread S1(3) in the diagram according to FIG. 5).

(38) In the case of the textile substrate 1C, in the region 1-1 the weft thread S1(1) crosses over the warp threads K1(1), K3(1), K5(1) of the first subset on a side facing the first surface O1 and crosses over the warp threads K2(1), K4(1), K6(1) of the first subset on a side facing the second surface O2. On the other hand, the weft thread S2(1) crosses over the warp threads K1(1), K3(1), K5(1) of the first subset on a side facing the second surface O2 and crosses over the warp threads K2(1), K4(1), K6(1) of the first subset on a side facing the first surface O1. Consequently, each of the warp threads of the first subset extending through the region 1-1 is embraced in opposite directions by the two weft threads S1(1) and S2(1) on opposite (facing the first surface O1 or the second surface O2) sides. Consequently, the warp threads and weft threads of the first subset extending through the region 1-1 are bound to one another and form a stable flatly configured unit which is integrated as a whole in the textile substrate 1C.

(39) The warp threads K1(2), K2(2), K3(2), K4(2), K5(2) of the second subset each cross over the weft threads S1(1) and S2(1) of the first subset on a side facing the first surface O1. Consequently the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset and the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), of the second subset are not bound to one another by the weft threads S1(1) and S1(2) of the first and second subset.

(40) In the present example all the warp threads of the second subset extending through the region 1-1 are bound by means of the weft thread S1(3) of the third subset to the warp threads and weft threads of the first subset. For this purpose the weft thread S1(3) is arranged in such a manner that it crosses over all the warp threads of the second subset extending through the region 1-1 on a side facing the first surface O1 and a plurality of the warp threads of the first subset extending through the region 1-1 on a side facing the second surface O2. As can be seen from FIG. 5, however it is not necessary that the weft thread S1(3) crosses over all the warp threads of the first subset extending through the region 1-1 on a side facing the second surface O2 (in the case of the textile substrate 1C the weft thread S1(3) crosses over the warp threads K2(1) and K5(1) on a side facing the first surface O1. The warp threads and weft threads of the first and second subset extending through the region 1-1 are nevertheless bound by means of the weft thread S1(3) of the third subset to form a stable layer, especially as the warp threads and weft threads of the first subset (as already mentioned) cross over one another in such a manner that they are bound to one another and form a stable flatly configured unit.

(41) If in the case of the textile substrate 1C the weft thread S1(3) of the third subset is destroyed according to the invention by using a suitable chemical and/or physical method, the warp threads and weft threads of the first subset can be separated in a simple manner from the warp threads and weft threads of the second subset. This is particularly apparent from FIG. 9. In the upper part of FIG. 9 the textile substrate 1C is shown in a state in which the weft thread S1(3) of the third subset is intact (according to the woven fabric section view according to FIG. 5). The lower part of FIG. 9 shows the relative arrangement of the warp threads and weft threads of the first and second subset extending through the region 1-1 for the case that the weft thread S1(3) in the textile substrate 1C is destroyed and completely removed (in a sectional view similar to the woven-fabric sectional view according to FIG. 5). As can be seen from FIG. 9, after destruction of the weft thread S1(3) of the third subset, the region 1-1 of the textile substrate 1C is decomposed into a stable flatly configured unit formed by the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) and weft threads S1(1) and S2(1) of the first subset bound to one another and a plurality of warp threads of the second subset. After destruction of the weft thread S1(3) of the third subset, the warp threads K1 (2), K2 (2), K3 (2), K4 (2), K5 (2) of the second subset are present as single loose warp threads which can be separated individually from the warp threads and weft threads of the first subset.

(42) FIG. 6 shows a region 1-1 of a textile substrate 1D according to the invention in a woven-fabric sectional view (in a section perpendicular to the respective warp threads). Through the region 1-1 there extends six warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset, at least two weft threads S1(1) and S2(1) of the first subset (and possibly further weft threads of the first subset which extend parallel to the weft threads S1(1) or S2(1) and would have the same profile as the respective weft threads S1(1) or S2(1) in the diagram according to FIG. 6), six warp threads K1 (2), K2 (2), K3 (2), K4(2), K5(2), K6(2) of the second subset, at least one weft thread S1(2) of the second subset (and possibly further weft threads of the second subset which extend parallel to the weft thread S1(2) and would have the same profile as the weft thread S1(2) in the diagram according to FIG. 6), and at least one weft thread S1(3) of the third subset (and possibly further weft threads of the third subset which extend parallel to the weft thread S1(3) and would have the same profile as the weft thread S1(3) in the diagram according to FIG. 6).

(43) In the case of the textile substrate 1D, the arrangement of the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset and weft threads S1(1), S2(1) of the first subset extending through the region 1-1 is identical to the arrangement of the corresponding warp threads and weft threads of the first subset which is found in the case of the textile substrate 1C (FIG. 5). Consequently, also in the case of the textile substrate 1D the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset and weft threads S1(1), S2(1) of the first subset extending through the region 1-1 are bound to one another and form a stable flatly configured unit which is integrated as a whole in the textile substrate 1D.

(44) In the case of the case of the textile substrate 1D, the arrangement of the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) and the weft thread S1(2) of the second subset is identical to the arrangement of the corresponding warp threads and weft threads of the second subset which is present in the case of the textile substrate 1B (FIG. 4).

(45) In the case of the textile substrate 1D the weft threads S1(1) and S2(1) of the first subset cross over all the warp threads K1 (2), K2 (2), K3 (2), K4 (2), K5(2), K6(2) of the second subset extending through the region 1-1 on a side facing the second surface O2 so that the weft threads S1(1) and S2(1) consequently bring about a spatial separation between the warp threads of the first subset and the warp threads of the second subset and the warp threads of the first subset extending through the region 1-1 are not bound by means of the weft threads S1(1) and S2(1) to the warp threads of the second subset extending through the region 1-1.

(46) The weft thread S1(2) of the second subset crosses over alternately all the warp threads of the second subset extending through the region 1-1 so that the weft thread S1(2) crosses over the warp threads K2(2), K4(2) and K6(2) on a side facing the first surface O1 and crosses over K1(2), K3(2) and K5(2) on a side facing the second surface O2. Furthermore the weft threads S1(2) of the second subset crosses over the warp threads of the first subset extending through the region 1-1 on a side facing the first surface O1. Consequently the warp threads warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset and the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) of the second subset are not bound to one another by the weft threads S1(1), S2(1) and S1(2) of the first and second subset.

(47) In the present example the weft thread S1(3) of the third subset extends through the region 1-1 in such a manner that it crosses over the warp threads K1(1), K2(1), K3(1), K4(1), K6(1) of the first subset on a side facing the second surface O2 and then crosses over the warp threads K1(2), K3(2), K4(2), K5(2), K6(2) of the second subset on a side facing the first surface O1. In this way all the warp threads and weft threads of the first and second subset extending through the region 1-1 are connected to one another by means of the weft thread S1(3) of the third subset in the region 1-1 to form a stable layer as long as the weft thread S1(3) is not destroyed.

(48) As can be seen from FIG. 6, however it is not necessary that the weft thread S1(3) crosses over all the warp threads of the first subset extending through the region 1-1 on a side facing the second surface O2 and all the warp threads of the second subset extending through the region 1-1 on a side facing the first surface O1 in order to connect the warp threads and weft threads stably to one another (in the case of the textile substrate 1D, the weft thread S1(3) crosses over the warp thread K5(1) of the first subset on a side facing the first surface O1 and crosses over the warp thread K2(2) of the second subset on a side facing the second surface O2). The warp threads and weft threads of the first and second subset extending through the region 1-1 are nevertheless bound by means of the weft thread S1(3) of the third subset to form a stable layer, especially as the warp threads and weft threads of the first subset (as already mentioned) cross over one another in such a manner that they are bound to one another and form a stable flatly configured unit and the warp thread K2(2) of the second subset is bound by means of the weft thread S1(2) to the warp threads and weft threads of the first subset as long as the weft thread S1(3) is not destroyed.

(49) If in the case of the textile substrate 1D the weft thread S1(3) of the third subset is destroyed according to the invention by using a suitable chemical and/or physical method, the warp threads and weft threads of the first subset can be separated in a simple manner from the warp threads and weft threads of the second subset. After destruction of the weft thread S1(3) of the third subset, the region 1-1 of the textile substrate 1D is decomposed into a stable flatly configured unit formed by the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) and weft threads S1(1) and S2(1) of the first subset bound to one another (similar to the arrangement of the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) and weft threads S1(1) and S2(1) of the first subset in the case of the textile substrate 1C, as shown in FIG. 9) and a plurality of warp threads of the second subset and the weft threads S1(2) of the second subset (similar to the arrangement of the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) and the weft thread S1(2) of the second subset in the case of textile substrate 1B, as shown in FIG. 8). After destruction of the weft thread S1(3) of the third subset, the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) and the weft thread S1(2) of the second subset are present as single loose threads which can be separated individually from the warp threads and weft threads of the first subset.

(50) FIG. 7 shows a region 1-1 of a textile substrate 1E according to the invention in a woven-fabric sectional view (in a section perpendicular to the respective warp threads). Through the region 1-1 there extends six warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset, at least two weft threads S1(1) and S2(1) of the first subset (and possibly further weft threads of the first subset which extend parallel to the weft threads S1(1) or S2(1) and would have the same profile as the weft threads S1(1) or S2(1) in the diagram according to FIG. 7), six warp threads K1 (2), K2 (2), K3 (2), K4(2), K5(2), K6(2) of the second subset, at least two weft threads S1(2) and S2(2) of the second subset (and possibly further weft threads of the second subset which extend parallel to the weft threads S1(2) or S2(2) and would have the same profile as the respective weft thread S1(2) or S2(2) in the diagram according to FIG. 7), and at least one weft thread S1(3) of the third subset (and possibly further weft threads of the third subset which extend parallel to the weft thread S1(3) and would have the same profile as the weft thread S1(3) in the diagram according to FIG. 7).

(51) In the case of the textile substrate 1E, the arrangement of the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) and weft threads S1(1), S2(1) of the first subset is identical to the arrangement of the corresponding warp threads and weft threads of the first subset which exists in the case of the textile substrate 1C (FIG. 5). Consequently, in the case of the textile substrate 1E, the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) and weft threads S1(1), S2(1) of the first subset extending through the region 1-1 are bound to one another and form a stable, flatly configured unit which is integrated as a whole in the textile substrate 1E.

(52) In the case of the textile substrate 1E, the weft thread S1(2) crosses over the warp threads K1(2), K3(2) and K5(2) of the second subset on a side facing the first surface O1 and crosses over the warp threads K2(2), K4(2) and K6(2) of the second subset on a side facing the second surface O2. On the other hand, the weft thread S2(2) crosses over the warp threads K1(2), K3(2), K5(2) of the second subset on a side facing the second surface O2 and crosses over the warp threads K2(2), K4(20, K6(2) of the second subset on a side facing the first surface O1. Consequently the warp threads of the second subset extending through the region 1-1 are embraced in opposite directions by the two weft threads S1(2) and S2(2) on opposite sides (facing the first surface O1 or the second surface O2). Consequently the warp threads and weft threads of the second subset extending through the region 1-1 are bound to one another and form a stable, flatly configured unit which is integrated as a whole in the textile substrate 1E.

(53) In the case of the textile substrate 1E, the weft threads S1(1) and S2(1) of the first subset cross over the warp threads of the second subset extending through the region 1-1 on a side facing the second surface O2 and the weft threads S1(2) and S2(2) of the second subset cross over the warp threads of the first subset extending through the region 1-1 on a side facing the first surface O1. Accordingly, the warp threads of the first subset extending through the region 1-1 are separated from the warp threads of the second subset extending through the region 1-1 by the weft threads S1(1) and S2(1) of the first subset or the weft threads S1(2) and S2(2) of the second subset and consequently are not bound to the warp threads of the second subset extending through the region 1-1.

(54) In the present example the weft thread S1(3) of the third subset extends through the region 1-1 in such a manner that it crosses over the warp threads K1(1), K2(1), K3(1), K4(1), K6(1) of the first subset on a side facing the second surface O2 and crosses over the warp threads K1(2), K3(2), K4(2), K5(2), K6(2) of the second subset on a side facing the first surface O1. In this way all the warp threads and weft threads of the first and second subset extending through then region 1-1 are connected to one another by means of the weft thread S1(3) of the third subset in the region 1-1 to form a stable layer as long as the weft thread S1(3) is not destroyed.

(55) If in the case of the textile substrate 1E the weft thread S1(3) of the third subset is destroyed according to the invention by using a suitable chemical and/or physical method, the warp threads and weft threads of the first subset can be separated in a simple manner from the warp threads and weft threads of the second subset. This is particularly apparent from FIG. 10. In the upper part of FIG. 10 the textile substrate 1E is shown in a state in which the weft thread S1(3) of the third subset is intact (according to the woven fabric section view according to FIG. 7). The lower part of FIG. 10 shows the relative arrangement of the warp threads and weft threads of the first and second subset extending through the region 1-1 for the case that the weft thread S1(3) in the textile substrate 1E is destroyed and completely removed (in a sectional view similar to the woven-fabric sectional view according to FIG. 7).

(56) As can be seen from FIG. 10, after destruction of the weft thread S1(3) of the third subset, the region 1-1 of the textile substrate 1E is decomposed into two stable flatly configured units: a first unit formed by the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) and weft threads S1(1) and S2(1) of the first subset bound to one another and a second unit formed by the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) and weft threads S1(2) and S2(2) of the second subset bound to one another. These two units can then be separated from one another.

(57) Although the textile substrate 1A-1E according to FIGS. 3-10 merely comprises two variously disposable and/or utilisable materials or a plurality of disposable and/or utilisable materials selected from merely two different utilisation groups, the invention also makes it possible to specify textile substrates which comprise three or more variously disposable and/or utilisable materials or a plurality of disposable and/or utilisable materials selected from three or more different utilisation groups and allows a separation of the various materials. This will be explained in the following with reference to two examples shown in FIGS. 11A-12C.

(58) FIG. 11B shows a region 1-1 of a textile substrate 1F according to the invention in a woven-fabric sectional view (in a section perpendicular to the respective warp threads). The textile substrate 1F can be seen as a further development of the textile substrate 1B according to FIG. 4. In order to facilitate a comparison, FIG. 11A contains a woven-fabric section view of the textile substrate 1B (identical to the view in FIG. 4). The textile substrate 1F is similar to the textile substrate 1B in regard to its structure insofar as it compriseslike the textile substrate B: six warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset, at least one weft thread S1(1) of the first subset (and possibly further weft threads of the first subset which extend parallel to the weft thread S1(1) and would have the same profile as the weft threads S1(1) in the diagram according to FIG. 11), six warp threads K1 (2), K2 (2), K3 (2), K4(2), K5(2), K6(2) of the second subset, at least one weft thread S1(2) of the second subset (and possibly further weft threads of the second subset which extend parallel to the weft thread S1(2) and would have the same profile as the weft thread S1(2) in the diagram according to FIG. 11B), at least one weft thread S1(3) of the third subset (and possibly further weft threads of the third subset which extend parallel to the weft thread S1(3) and would have the same profile as the weft thread S1(3) in the diagram according to FIG. 11B).

(59) In the case of the textile substrate 1F, the arrangement of the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) and the weft thread S1(1) of the first subset extending through the region 1-1 and of the warp threads K1 (2), K2 (2), K3 (2), K4 (2), K5(2), K6(2) and the weft thread S1(2) of the second subset extending through the region 1-1 relative to one another is identical to the arrangement of the corresponding warp threads and weft threads of the first subset and the second subset which exists in the case of the textile subset 1B (FIG. 11A).

(60) Unlike the textile substrate 1B, the textile substrate 1F comprises three warp threads K1(4), K2(4), K3(4) of the fourth subset and at least one weft thread S1(4) of the fourth subset (and optionally further weft threads of the fourth subset which extend parallel to the weft thread S1(4)). In the case of the textile substrate 1F, the respective warp threads and weft threads of the fourth subset are arranged in an inner zone IZ (shown as a dotted area in FIG. 11B) which extends between the respective warp threads and weft threads of the first subset and the respective warp threads and weft threads of the second subset. In the present example, the warp threads K1(4), K2(4), K3(4) and the weft thread S1(4) of the fourth subset extend in such a manner in the inner zone IZ that the warp threads K1(4), K2(4), K3(4) of the fourth subset cross over the weft thread S1(1) of the first subset on a side facing the first surface O1, the weft thread S1(4) of the fourth subset on a side facing the second surface O2 and the weft thread S1(2) of the second subset on a side facing the second surface O2. Furthermore, the weft thread S1(4) of the fourth subset crosses over the warp threads of the second subset extending through the region 1-1 on a side facing the second surface O2.

(61) The arrangement of the warp threads K1(4), K2(4), K3(4) and the weft thread S1(4) in the inner zone ensures that the warp threads of the first, second and fourth subset extending through the region 1-1 are not bound to one another by the weft threads S1(1), S1 (2) and S1(4).

(62) In the case of the textile substrate 1F, the weft thread S1(3) of the third subset extends through the region 1-1 in such a manner that it crosses over all the warp threads of the first subset extending through the region 1-1 on a side facing the second surface O2 and additionally crosses over the warp threads K1(2), K3(2), K4(2), K5(2), K6(2) of the second subset on a side facing the first surface O1. In this way, all the warp threads and weft threads of the first, second and fourth subset extending through the region 1-1 are connected to one another by means of the weft thread S1(3) of the third subset in the region 1-1 to form a stable layer as long as the weft thread S1(3) is not destroyed.

(63) If, in the case of textile substrate 1F the weft thread S1(3) of the third subset is destroyed according to the invention by application of a suitable chemical and/or physical method, the textile substrate is then decomposed into an arrangement of crossing-over threads which lie loosely next to one another or above one another and which can be separated individually from one another. As can be seen from FIG. 11B, the warp threads of the second and fourth subset are separated by the weft thread S1(4) of the fourth subset and the warp threads of the first and fourth subset are separated by the weft threads S1(1) of the first subset. After destruction of the weft thread S1(3) of the third subset it is thereby possible to separate the respective warp threads and weft threads of the first, second and fourth subset in layers.

(64) FIG. 12B shows a region 1-1 of a textile substrate 1G according to the invention in a woven-fabric sectional view (in a section perpendicular to the respective warp threads). The textile substrate 1G can be seen as a further development of the textile substrate 1E according to FIG. 7. In order to facilitate a comparison, FIG. 12A contains a woven-fabric sectional view of the textile substrate 1E (identical to the view in FIG. 7). The textile substrate 1F is similar to the textile substrate 1B in regard to its structure insofar as it comprises: six warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) of the first subset, at least two weft threads S1(1) and S(2)1 of the first subset, six warp threads K1 (2), K2 (2), K3 (2), K4(2), K5(2), K6(2) of the second subset, at least two weft threads S1(2) and S2(2) of the second subset, at least one weft thread S1(3) of the third subset.

(65) In the case of the textile substrate 1G, the arrangement of the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) and the weft threads S1(1) and S2(1) of the first subset extending through the region 1-1 and of the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) and the weft threads S1(2) and S2(2) of the second subset extending through the region 1-1 relative to one another is identical to the arrangement of the corresponding warp threads and weft threads of the first subset and the second subset which exists in the case of the textile subset 1E (FIG. 12A).

(66) Unlike the textile substrate 1E, the textile substrate 1G comprises warp threads K(4) and weft threads S (4) of the fourth subset. In the case of the textile substrate 1G, the respective warp threads and weft threads of the fourth subset are arranged in an inner zone IZ (shown as a dotted area in FIG. 12B) which extends between the respective warp threads and weft threads of the first subset and the respective warp threads and weft threads of the second subset.

(67) As in the case of the textile substrate 1E, in the case of the textile substrate 1G the warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6(1) and weft threads S1(1), S2(1) of the first subset extending through the region 1-1 are bound to one another and form a stable, flatly configured unit which is integrated as a whole into the textile substrate 1G. Accordingly, the warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) and weft threads S1(1), S2(1) of the second subset extending through the region 1-1 are bound to one another and form a stable, flatly configured unit which is integrated as a whole into the textile substrate 1G.

(68) The warp threads K(4) and weft threads S(4) of the fourth subset can be arranged in various ways in the inner zone IZ in such a manner that none of the respective warp threads K(4) or weft threads S(4) is bound to the warp threads and weft threads of the first and second subset. FIG. 12C shows examples (a)-(d) for possible arrangement of warp threads K(4) and weft threads S(4) which cross the weft threads or warp threads of the first subset on a side facing the first surface O1 and which cross the weft threads or warp threads of the second subset on a side facing the second subset O2. According to Example (a), exclusively weft threads S(4) can be arranged in the inner zone IZ. According to Example (b), exclusively warp threads K(4) can be arranged in the inner zone IZ. According to Examples (c) and (d) both warp threads K(4) and weft threads S(4) can be arranged in the inner zone IZ.

(69) In the case of the textile substrate 1G, the weft thread S1(3) of the third subset extends through the region 1-1 in such a manner that it crosses over a plurality of warp threads of the first subset extending through the region 1-1 on a side facing the second surface O2 and additionally crosses over a plurality of warp threads of the second subset on a side facing the first surface O1. In this way, all the warp threads and weft threads of the first, second and fourth subset extending through the region 1-1 are connected to one another by means of the weft thread S1(3) of the third subset in the region 1-1 to form a stable layer as long as the weft thread S1(3) is not destroyed.

(70) If, in the case of textile substrate 1G the weft thread S1(3) of the third subset is destroyed according to the invention by application of a suitable chemical and/or physical method, the warp threads and weft threads of the first, second and fourth subset can then be separated. After destruction of the weft thread S1(3) of the third subset, both the warp threads and weft threads of the first subset and also the warp threads and weft threads of the second subset are each present as separate flatly configured units formed from warp threads K1(1), K2(1), K3(1), K4(1), K5(1), K6 (1) and weft threads S1(1) and S2(1) of the first subset bound to one another on the one hand and from warp threads K1(2), K2(2), K3(2), K4(2), K5(2), K6(2) and weft threads S1(2) and S2(2) of the second subset bound to one another on the other hand.

(71) It is also possible to modify the textile substrates 1A, 1C and 1D according to the examples according to FIGS. 11B and 12B by arranging the warp and/or weft threads of the fourth subset in an inner zone formed between the respective warp and/or weft threads of the first subset and the respective warp and/or weft threads of the second subset so that the warp and/or weft threads of the first, second and fourth subset are not bound to one another when the respective weft threads of the third subset are destroyed.

EXAMPLES

Example 1

(72) The textile substrate 1D according to FIG. 6 can be executed, for example, as follows: Subset 1 comprises warp threads and weft threads of wool and cellulose regenerate. Subset 2 comprises warp threads and weft threads of polyamide. Subset 3 comprises weft threads of polyvinyl alcohol (PVA).

(73) Such a textile substrate is suitable in particular as a seat cover textile. The warp threads and weft threads of wool and cellulose regenerate (subset 1) enable an air-conditioned seating and are relevant for moisture regulation. Polyamide (subset 2) increases the abrasion resistance of the textile substrate on one side of the substrate so that this side can preferably be used as a seating surface. Subset 1 can be disposed of in a biological cycle, subset 2 can be processed in a technical cycle.
