[0046] The figures are not necessarily to scale, and certain features and certain views of the figures may be shown exaggerated in scale or in schematic form in the interests of clarity and conciseness,

[0047] The following embodiments of the invention are described with reference to stretchable textile articles made of woven textiles, but it will be appreciated that the working principle of each of the following embodiments of the invention is applicable mutatis mutandis to stretchable textile articles made of non-woven textiles,

[0048] A stretchable textile article according to a first embodiment of the invention is shown in FIG. 1 and is designated generally by the reference numeral 20.

[0049] The stretchable textile article 20 comprises a plurality of discrete textile members 22,24. Each textile member 22,24 is in the form of a textile strip extending between a first end 26 and a second end 28. The first ends 26 of the plurality of textile members 22,24 are joined together via a first textile section 30, and the second ends 28 of the plurality of textile members 22,24 are joined together via a second textile section 32. The plurality of textile members 22,24 extends parallelly, or substantially parallelly, between the joined first ends 26 and the joined second ends 28, such that the plurality of textile members 22,24 flank each other between the joined first ends 26 and the joined second ends 28. Each textile member 22,24 is spaced apart from each neighbouring textile member 22,24 between the joined first ends 26 and the joined second ends 28.

[0050] Preferably the first and second textile sections 30,32 are non-stretchable, or rigid, textile sections. That is to say, the stretch properties of the first and second textile sections 30,32 are selected so that the first and second textile sections 30,32 exhibit non-stretchability.

[0051] The plurality of textile members 22,24 includes a plurality of first textile members 22 and a plurality of second textile members 24. The first and second textile members 22,24 are arranged to form alternately positioned first and second textile members 22,24 between the joined first ends 26 and the joined second ends 28.

[0052] Each textile member 22,24 is made from an elastic woven textile material, and includes a textile zone extending fully along the length of the textile member 22,24. Each textile zone is configured to have a variable stretch property in an orientation extending between the joined first ends 26 and the joined second ends 28. More specifically, the textile zone of each first textile member 22 has a continuously increasing stretch property along the length of the textile strip away from the first end 26 towards the second end 28, and the textile zone of each second textile member 24 has a continuously increasing stretch property the length of the textile strip away from the second end 28 towards the first end 26. FIG. 2 shows the variation of the stretch property along the length of each textile member 22,24.

[0053] The variable stretch property of the textile zone of each textile member 22,24 may be obtained by varying the textile characteristics of each textile member 22,24. This may include, for example, varying the weave construction (a tighter weave results in a lower stretch property, and a looser weave results in a higher stretch property), or changing the yarn density.

[0054] The stretchable textile article 20 can be stretched by applying a tensile load 34 to the joined first ends 26 and the joined second ends 28. Since the respective stretch properties of the textile zones of the first and second textile members 22,24 increase continuously in opposite directions between the first and second ends 26,28, the application of the tensile load 34 results in relative stretch between the first and second textile members in opposite directions. This causes a portion of each first textile member 22 positioned towards the second end 28 to stretch 36 towards a portion of each second textile member 24 positioned towards the first end 26, and causes the portion of each second textile member 24 positioned towards the first end 26 to stretch 38 towards the portion of each first textile member 22 positioned towards the second end 28, as shown in FIG. 3. As a result, the distance between the two portions is reduced. In the event of the application of a sufficiently large tensile load 34, an overlap between the two portions can be obtained.

[0055] FIG. 4 shows a side-by-side comparison of the unstretched and stretched states of the stretchable textile article 20. ‘X’ markers are used to illustrate the stretch behaviour of the first and second textile members 22,24, and therefore the relative stretch between the first and second textile members 22,24.

[0056] The combination of the plurality of discrete textile members 22,24 joined at the first and second ends 26,28 and the inclusion of a textile zone having a variable stretch property in each textile member 22,24 therefore provides a multi-modulus stretchable textile article 20. The variable stretch property, shape and size of each discrete textile member 22,24 can be varied to customise the stretch properties of the stretchable textile article 20 to match the requirements of a wide range of textile products and applications.

[0057] As a result of the structure of the stretchable textile article 20, it is more effective to stretch the stretchable textile article 20 by gradually applying the tensile load as opposed to suddenly applying the tensile load, e.g. by using a snapping pulling motion.

[0058] Optionally, after stretching the stretchable textile article 20, a fastener may be used to releasably fasten the first and second textile members 22,24 together at a fastening point or region between the first and second ends 26,28. Such a fastener may be in the form of a clip that extends across the first and second textile members 22,24. The clip may be replaced by a different type of fastener. Examples of other fasteners are described elsewhere in this specification.

[0059] Further optionally the clip may be used to fasten the first and second textile members 22,24 together when the stretchable textile article 20 is in an unstretched state. Alternatively or additionally, the clip may be used to fasten the first and second textile members 22,24 together when the stretchable textile article 20 is in a stretched state. It will be appreciated that the stretchable textile article 20 can have multiple stretched states by varying the applied tensile load 34, and hence the clip may be used to fasten the first and second textile members 22,24 together in more than one stretched state of the stretchable textile article 20.

[0060] By clipping the first and second textile members 22,24 to each other, the overall stretch properties of the stretchable textile article 20 can be temporarily fixed until the clip is released. In this manner, the overall stretch properties of the stretchable textile article 20 may be modified through use of the fastener.

[0061] It is envisaged that, in other embodiments of the invention, the first and second textile members may be arranged between the first and second ends in other ways instead of alternately positioning the first and second textile members 22,24 between the first and second ends 26,28. For example, the textile members may be arranged so that the first textile members are grouped together at one side of the stretchable textile article, and the second textile members are grouped together at the other side of the stretchable textile article.

[0062] It is also envisaged that. in still other embodiments of the invention, the stretchable textile article 20 of FIG. 1 may include a single first textile member instead of a plurality of first textile members 22, and/or a single second textile member instead of a plurality of second textile members 24.

[0063] It is further envisaged that, in further other embodiments of the invention, the stretchable textile article 20 of FIG. 1 may include a plurality of fasteners, the or each fastener being configurable to releasably fasten the first and second textile members 22,24 together at a respective fastening point or region between the first and second ends 26,28.

[0064] A stretchable textile article according to a second embodiment of the invention is shown in FIG. 5 and is designated generally by the reference numeral 120. The stretchable textile article 120 of FIG. 5 is similar in construction to the stretchable textile article 20 of FIG. 1, and like features share the same reference numerals.

[0065] The stretchable textile article 120 of FIG. 5 differs from the stretchable textile article 20 of FIG. 1 in that, in the stretchable textile article 120 of FIG. 5, the textile zone of the first textile member 22 has a discontinuously increasing stretch property along the length of the textile strip away from the first end 26 towards the second end 28, and the textile zone of the second textile member 24 has a discontinuously increasing stretch property along the length of the textile strip away from the second end 28 towards the first end 26.

[0066] More specifically, as shown in FIG. 6, the textile zone of each textile member 22,24 includes first and second textile sub-zones 40,42,44,46 arranged successively along the length of the textile member 22,24 between the first and second ends 26,28. The first and second textile sub-zones 40,42,44,46 of each textile member 22,24 are positioned towards the first and second ends 26,28 respectively.

[0067] The textile sub-zone 40 of each first textile member 22 adjacent the first end 26 has a respective constant or substantially constant stretch property, and the textile sub-zone 42 of each first textile member 22 adjacent the second end 28 has a continuously increasing stretch property along the length of the textile sub-zone 42 away from the first end 26 towards the second end 28. The textile sub-zone 44 of each second textile member 24 adjacent the first end 28 has a respective constant or substantially constant stretch property, and the textile sub-zone 46 of each second textile member 24 adjacent the second end 28 has a continuously increasing stretch property along the length of the textile sub-zone 46 away from the second end 28 towards the first end 26.

[0068] The stretch properties of the first and second textile sub-zones 40,42 of each first textile member 22 are selected so that the first and second textile sub-zones 40,42 of each first textile member 22 respectively exhibit non-stretchability and stretchability. The stretch properties of the first and second textile sub-zones 44,46 of each second textile member 24 are selected so that the first and second textile sub-zones 44,46 of each second textile member 24 respectively exhibit stretchability and non-stretchability.

[0069] In the embodiment shown, the textile sub-zones 40,42,44,46 of the first and second textile members 22,24 are arranged so that, when the stretchable textile article 120 is in an unstretched state, the non-stretchable first textile sub-zone 40 of each first textile member 22 overlaps with the non-stretchable second textile sub-zone 46 of each second textile member 24.

[0070] In a similar fashion to the embodiment of FIG. 1, applying a tensile load 34 to the joined first ends 26 and the joined second ends 28 results in relative stretch 36,38 between the first and second textile members 22,24 in opposite directions, as shown in FIG. 7. This results in a reduction in overlap between the non-stretchable textile sub-zones 40,46 and therefore a reduction in distance between the stretchable textile sub-zones 42,44 as a result of the non-deformation, or minimal deformation, of the non-stretchable textile sub-zones 40,46, as shown in FIG. 7. In the event of the application of a sufficiently large tensile load 34, an overlap between the stretchable textile sub-zones 42,44 can be obtained.

[0071] FIG. 8 shows a side-by-side comparison of the unstretched and stretched states of the stretchable textile article 120.

[0072] A stretchable textile article according to a third embodiment of the invention is shown in FIGS. 9a, 9b and 9c and is designated generally by the reference numeral 220. The stretchable textile article 220 of FIGS. 9a, 9b and 9c is similar in construction to the stretchable textile article 20 of FIG. 1, and like features share the same reference numerals.

[0073] The stretchable textile article 220 of FIGS. 9a, 9b and 9c differs from the stretchable textile article 20 of FIG. 1 in that, in the stretchable textile article 220 of FIGS. 9a, 9b and 9c:

[0074] the plurality of textile members 22,24 includes a single first textile member 22 and a single second textile member 24;

[0075] the textile members 22,24 are arranged to extend parallelly, or substantially parallelly, between the joined first ends 26 and the joined second ends 28, and overlie each other between the joined first ends 26 and the joined second ends 28; and

[0076] the first ends 26 of the first and second textile members 22,24 are stitched together, and the second ends 28 of the first and second textile members 22,24 are stitched together.

[0077] FIG. 9a is a top view of the stretchable textile article 220, which shows the first textile member 22. FIG. 9b is a side view of the stretchable textile article 220, which shows both the first and second textile members 22,24. FIG. 9c is a bottom view of the stretchable textile article 220, which shows the second textile member 24.

[0078] The textile zone of the first textile member 22 has a discontinuously increasing stretch property along the length of the textile strip away from the first end 26 towards the second end 28, and the textile zone of the second textile member 24 has a discontinuously increasing stretch property along the length of the textile strip away from the second end 28 towards the first end 26.

[0079] More specifically, as shown in FIG. 10, the textile zone of each textile member 22,24 includes first and second textile sub-zones 40,42,44,46 arranged successively along the length of the textile member 22,24 between the first and second ends 26,28. The first and second textile sub-zones 40,42,44,46 of each textile member 22,24 are positioned towards the first and second ends 26,28 respectively. Each textile sub-zone 40,42.44,46 has a respective constant or substantially constant stretch property. The stretch properties of the first and second textile sub-zones 40,42 of the first textile member 22 are selected so that the first and second textile sub-zones 40,42 of the first textile member 22 respectively exhibit non-stretchability and stretchability. The stretch properties of the first and second textile sub-zones 44,46 of the second textile member 24 are selected so that the first and second textile sub-zones 44,46 of the second textile member 24 respectively exhibit stretchability and non-stretchability.

[0080] In the embodiment shown, the textile sub-zones 40,42,44,46 of the first and second textile members 22,24 are arranged so that, when the stretchable textile article 220 is in an unstretched state, the non-stretchable first textile sub-zone 40 of the first textile member 22 overlaps with the non-stretchable second textile sub-zone 46 of the second textile member 24.

[0081] In a similar fashion to the embodiment of FIG. 1, applying a tensile load 48 to the joined first ends 26 and the joined second ends 28 results in relative stretch 50 between the first and second textile members 22,24 in opposite directions. This results in a reduction in overlap between the non-stretchable textile sub-zones 40,46 and therefore a reduction in distance between the stretchable textile sub-zones 42,44 as a result of the non-deformation, or minimal deformation, of the non-stretchable textile sub-zones 40,46, as shown in FIG. 11, In the event of the application of a sufficiently large tensile load 48, an overlap between the stretchable textile sub-zones 42,44 can be obtained.

[0082] FIG. 12 shows a side-by-side comparison of the unstretched and stretched states of the stretchable textile article 220.

[0083] After stretching the stretchable textile article 220 so that the overlap between the non-stretchable textile sub-zones 40,46 is reduced and so that the distance between the stretchable textile sub-zones 42,44 is reduced, a fastener 52 may be used to clip the non-stretchable textile sub-zones 40,46 together at the region of overlap, as shown in FIG. 13. Clipping the non-stretchable textile sub-zones 40,46 to each other prevents further stretch of the stretchable textile sub-zones 42,44 and therefore prevents further stretch of the stretchable textile article 220.

[0084] Optionally the fastener 52 may be also used to clip the non-stretchable textile sub-zones 40,46 together at the region of overlap when the stretchable textile article 220 is in an unstretched state, so as to prevent stretching of the stretchable textile article 220. as shown in FIG. 14.

[0085] It is envisaged that, in other embodiments of the invention, the stretchable textile article 220 of FIGS. 9a, 9b and 9c may include a plurality of first textile members instead of a single first textile member 22, and/or a plurality of second textile members instead of a single second textile member 24.

[0086] It is also envisaged that, in still other embodiments of the invention, the textile sub-zones 40,42,44,46 of the first and second textile members 22,24 are arranged so that, when the stretchable textile article 220 is in an unstretched state;

[0087] the stretchable first textile sub-zone 44 of the second textile member 24 overlaps with the stretchable second textile sub-zone 42 of the first textile member 22; or

[0088] the non-stretchable first textile sub-zone 40 of the first textile member 22 overlaps with the stretchable first textile sub-zone 44 of the second textile member 24 but does not overlap with the non-stretchable second textile sub-zone 46 of the second textile member 24, while the stretchable second textile sub-zone 42 of the first textile member 22 overlaps with the non-stretchable second textile sub-zone 46 of the second textile member 24 but does not overlap with the stretchable first textile sub-zone 44 of the second textile member 24.

[0089] Each of the embodiments 20,120,220 of FIG. 1, FIG. 5 and FIGS. 9a, 9b and 9c may be used as a structural support component for a garment.

[0090] In one example, the embodiment 20,120,220 of FIG. 1, FIG. 5 or FIGS. 9a, 9b and 9c is configured as a strap for a brassiere. After the brassiere is worn resulting in a stretched strap, the first and second textile members 22,24 can be fastened together to prevent further stretch of the strap, thus securing the brassiere in place. In another example, the embodiment 20,120,220 of FIG. 1, FIG. 5 or FIGS. 4a, 4b and 4c is configured as a waistband for a pair of trousers. After the pair of trousers is worn resulting in a stretched waistband, the first and second textile members 22,24 can be fastened together to prevent further stretch of the waistband, thus securing the pair of trousers in place. This obviates the need for a drawstring around the waistband.

[0091] Each of the embodiments 20,120,220 of FIG. 1, FIG. 5 and FIGS. 4a, 4b and 4c may be configured as a different type of structural support component, other than a strap or a band. Each of the embodiments 20,120,220 of FIGS. 1, FIG. 5 and FIGS. 4a, 4b and 4c may be used in another type of garment, a bag, a seat belt, footwear, or a technical textile,

[0092] It will be appreciated that, in embodiments of the invention, the textile zone of each textile member may be divided into any number of a plurality of textile sub-zones having different stretch properties.

[0093] It will also be appreciated that shading and/or hatching is used in the figures for clarity of illustration of the different features of the embodiments.
