(32) The weft yarns are inserted into the warp according to traditional techniques using the looms usually used for the weaving of this type of articles.

(33) The weaving preferably used is a simple canvas, as illustrated in the warp profile in FIG. 5.

(34) Preferably the yarns count constituting the weft and the warp is 100-700 dtex, more preferably 350-650 dtex, preferably 550-600 dtex for the yarn A and 420-480 dtex for the yarn B; the warp yarns may be parallel but preferably are twisted and elasticized, while those of the weft may be indifferently twisted or parallel and elasticized.

(38) Lamination

(39) In the laminated fabric according to the invention, the two fabrics, upper and lower, are laminated by means traditional bonding techniques known by the application between the two fabrics of an adhesive means or by quilting, seam between them, of the 2 layers. Among the known bonding techniques, polyurethane (PU) or reactive polyurethane (PUR) lamination, powder coupling, PU film or PL lamination, web lamination, latex lamination are preferred.

(40) The aforesaid adhesive means (also called glue) can be applied by blade, by points or by hot transfer, preferably according to the present invention the selected lamination is reactive polyurethane (PUR) by points, as it allows to maintain exceptional properties of breathability, elasticity, softness without minimally altering the gluing power between the layers, with tightness and resistance to all environmental aging (high temperatures, low temperatures, acid sweat, alkaline sweat, water, etc.) to which the material is subjected.

(41) Preferably, both the upper fabric and the lower fabric, before proceeding to the final phase of PUR by point lamination, preferably in quantities of 30-50 g/m.sup.2, take advantage of a good preparation to eliminate all the stiffening agents present on the fibers applied in spinning, warping and weaving steps and possible impurities present in the fibers or collected during the previous workings.

(42) Preferably then, to eliminate all impurities present in the fabric and favor the re-entry and closing of the fibers, which may also be about 25% in both directions if there is the preferred presence of an elastomer both in the weft and in the warp, both the upper and lower fabrics are purged in width, procedure carried out with water and addition of possible detergent soaps, at a temperature of about 90 C. After washing, the fabric must be dried and thermofixed, preferably with a passage carrying out drying in ramosa at a temperature of 165 C., speed of 25 m/min, then always in ramosa thermofixing at a temperature of 180 C., speed of 25 m/min. The thermofixing serves to give permanent stability for all subsequent procedure (laminaton, dyeing, printing, finishing, industrial washing or domestic washing, etc.). After the thermofixing we proceed with the equalization, a rolling operation with application of steam, to homogenize the surface and to recover softness to the fabric, hardened and strain hardened by the thermofixing.

(43) If the upper fabric and/or the lower fabric contain UHMWPE yarns (for example Dyneema), the drying and thermofixing phase must be carried out in tumbler, the industrial equivalent of the domestic dryer, which works at temperatures below 100 C., but which performs an important mechanical action given by the centrifugation basket, which determines the maximum re-entry of the fibers, to obtain the same results in terms of dimensional stability of the ramosa. For fabrics in which dyneema fiber (UHMWPE) is present tumbler drying is required because above 110 C. said fiber starts to soften and then melts, completely losing the characteristics that make it one of the most resistant fibers to abrasion, cut and tear on the market. This operation in tumbler is more expensive and time-consuming compared to the thermofixing in ramosa, reason why, if not forced by technical reasons, it is preferably avoided.

(44) Once the 2 fabrics have been prepared as described above, we can proceed with the reactive polyurethane (PUR) lamination by points.

(45) This procedure is preferably carried out on cold, on a machine where the thermoplastic PUR is dissolved from the pressure plate heated to about 115 C. (accessory external to the machine) and pushed through a pump to the micro-perforated cylinder for application on the fabrics. Immediately after the application of the glue, the 2 laminated fabrics are crushed by a calender which applies a pressure of about 2.5 tons and immediately rolled up to form a large roll, which remains stationary to cross-link in a heated environment where the temperature must never fall below 15 C. (limit temperature which crystallizes the PUR rendering it ineffective). The cross-linking time depends on the external temperature, at 20 C. 24 h of cross-linking are enough (the minimum time below which it can not be lowered), below 20 C. the cross-linking time proportionally extends it with the decrease the temperature itself.

(46) The advantage of this type of lamination is that once the cross-linking is completed, the PUR does not go back any more, neither with high nor with low temperatures, and gives a permanent seal to all the expected environmental aging and to all the domestic and industrial washings.

(47) The present invention can be better understood in the light of the following embodiment examples.

(101) The upper fabric is purged in width, operation carried out with water and addition of possible detergent soaps, at a temperature of 90 C., to eliminate all impurities present in the fabric and favor the re-entry and closure of the fibers, that in this case can be very high thanks to the preferred presence of the elastomer both in the weft and in the warp, about 25% in both directions, after washing it is dried with a passageway in ramosa at a temperature of 165 C., speed of 25 m/min, then always in ramosa it is thermofixed at a temperature of 180 C., a speed of 25 m/min, to give permanent stability for all subsequent procedures (lamination, dyeing, printing, finishing, industrial washing or domestic washing, etc.); after thermofixing, proceed with the equalization, a roll-up operation with application of steam, to homogenize the surface and allow the fabric to recover softness, hardened and strain hardened by the thermofixing.

(102) The lower fabric is purged in width exactly as described above for the upper fabric, but the drying and thermofixing phase is carried out in tumbler, the industrial equivalent of the domestic dryer, which works at temperatures below 100 C., but with a important mechanical action given by the centrifuge basket, which determines the maximum re-entry of the fibers, to obtain the same results in terms of dimensional stability of the ramosa. This fabric requires tumbler drying when the dyneema fiber (UHMWPE) is present inside the fabric, because above 110 C. it starts to soften and then melts, completely losing the characteristics that make it one of the most resistant fibers to abrasion, cut and tear on the market. This operation is more expensive and time-consuming compared to the thermofixing in ramosa, reason why, if not required for technical reasons, it is preferably avoided. Once the 2 fabrics have been prepared as described above, we can proceed with reactive polyurethane (PUR) lamination by points using an amount of PUR equal to 30-50 g/m.sup.2.

(103) This operation is carried out on cold, on a machine where the thermoplastic PUR is melted from the pressing plate heated to about 115 C. (accessory external to the machine) and pushed by a pump to the micro-perforated cylinder for application on the fabrics, immediately after the application of the glue, the 2 laminated fabrics are crushed by a calender that applies a pressure of about 2.5 tons and immediately rolled up to form a large roll, which remains stationary to cross-link in a heated environment where the temperature must never fall below 15 C. (limit temperature that crystallizes the PUR making it ineffective), the cross-linking time depends on the external temperature, at 20 C. 24 h of cross-linking is enough (the minimum time below which it cannot be lowered), below the 20 C. the cross-linking time proportionally extends with the decrease of the temperature itself.

(104) The resulting laminated fabric has, in the case of lamination with upper fabric as ex. 4, a weight of less than 1000 g/m.sup.2 and a thickness of less than 1.5 mm and has demonstrated an abrasion resistance according to EN 13595 Standard >16 seconds.
