Detailed Description

The following description of the preferred embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1, the waterproof breathable composite fabric comprises a fabric layer 1, a hot melt adhesive film layer 2 and a bottom fabric layer 3 which are sequentially attached, wherein the fabric layer 1 is a waterproof treated double-layer plain woven fabric, the double-layer plain woven fabric comprises a surface layer 11 and a bottom layer 12, the surface layer 11 is a 1/1 plain weave, the bottom layer 12 is a 10/1 satin weave, the bottom layer 11 and the surface layer 12 share warps 111-122, the bottom fabric layer 3 is a fabric formed by a warp plain weave of an open loop, and the bottom layer 12 and the bottom fabric layer 3 of the fabric layer 1 are respectively bonded and attached to the hot melt adhesive film layer 2 in a surface heating melting state to form an integral fabric.

The double-layer plain woven fabric structure of the utility model is as shown in fig. 2 and fig. 3, the surface layer 11 of the double-layer plain woven fabric is 1/1 plain weave, the warp and the weft (first weft 112) are both 70D nylon-coated 40D spandex structures, wherein, the warp 111 of the surface layer is 1 yarn, the first weft 112 adopts 6 wefts to be circularly woven, the first 5 wefts are 1 yarn, and the sixth weft is 3 yarns; the bottom layer 12 of the double-layer plain woven fabric is a 10/1 satin weave, the bottom layer and the surface layer share warp yarns, the 1 st, 11 th and 21 st.. 10n +1 (n is more than or equal to 0) is warp yarns 111-122 interwoven with the second weft, and the weft yarn (the second weft 121) of the bottom layer adopts 300D low stretch yarn, so that the woven bottom layer is flat and solid in structure, easy to combine with a membrane, large in combination surface and good in stability; the base fabric adopts a warp knitting structure as shown in figure 4, and the yarns adopt 300D terylene, so that the base fabric has better elasticity and can more effectively maintain the structural stability with the membrane when being bonded with the membrane; the hot melt adhesive film is purchased from Jiangsu and New materials GmbH (hot melt adhesive model: L349B); the bonding of precoat, hot melt adhesive film layer and base cloth layer uses the compounding machine to adopt the hot pressing technology to carry out the complex: the temperature of the oven is 155 +/-5 ℃, the pressure of the roller is 0.2MPa +/-5 KPa, the composite fabric is subjected to heat preservation for 1.5min by a heat preservation oven (the length of the heat preservation oven is 30 m, three layers of cloth are arranged in the heat preservation oven, and the cloth speed is 60 m/min), and then the composite fabric is naturally cooled to the room temperature.
