Description

Technical Field

[0001] The utility model relates to the technical field of composite fabrics, in particular to a weather-resistant polyurethane composite fabric. Background Art

[0002] Polyurethane, also known as spandex, is a highly elastic fiber. Polyurethane fabric is a very commonly used chemical fiber clothing fabric in daily life. It has high strength and elastic recovery ability, and has good wrinkle resistance and shape retention.

[0022] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] Example

[0024] like Figures 1 to 3 As shown, a weather-resistant polyurethane composite fabric includes: a substrate layer 1, an antistatic flame retardant layer 2, a waterproof and breathable layer 3 and a moisture-permeable inner layer 4, the antistatic and flame retardant layer 2 is fixedly connected to the upper surface of the substrate layer 1, the waterproof and breathable layer 3 is fixedly connected to the upper surface of the antistatic and flame retardant layer 2, and the moisture-permeable inner layer 4 is fixedly connected to the lower surface of the substrate layer 1.

[0025] The base material layer 1 comprises a plurality of groups of warp yarns 101 and weft yarns 102 which are prepared by cross-weaving. The warp yarns 101 are formed by mixing nylon fibers and polyurethane fibers, and the weft yarns 102 are formed by mixing cotton fibers and polyurethane fibers. The warp yarns 101 are blended with high-strength and tough nylon fibers and polyurethane fibers, and the weft yarns 102 are blended with moisture-absorbing and breathable cotton fibers and polyurethane fibers. Thus, the fabric has excellent properties such as high strength and toughness, good moisture-absorbing and breathable effects, and good weather resistance, thereby improving the service life of the fabric.

[0026] The antistatic flame retardant layer 2 is composed of conductive fiber filaments 201, glass fibers 202 and polyester fibers 203. The glass fibers 202 and polyester fibers 203 are wrapped around the outside of the conductive fiber filaments 201 in a cross-spiral shape. The conductive fiber filaments 201 increase the antistatic property of the fabric, eliminate the harm of static electricity to the human body and the discomfort caused by static electricity when putting on and taking off, and eliminate the situation of clothes sticking to the body and entanglement caused by static electricity. The glass fibers 202 and polyester fibers 203 make the fabric have the characteristics of high temperature resistance and good flame retardant effect. The glass fibers 202 and polyester fibers 203 are wrapped around the outside of the conductive fiber filaments 201 in a cross-spiral manner to form a double-coated yarn structure with stable structure, and can reduce the thickness of the fabric and improve wearing comfort.

[0027] The waterproof and breathable layer 3 is made of PTFE membrane material. The PTFE membrane is a microporous film made of polytetrafluoroethylene dispersed resin through special processes such as premixing, extrusion, calendering, and biaxial stretching. It allows water vapor to pass through, but water droplets cannot pass through. This microporous structure can achieve excellent waterproof and moisture-permeable functions, preventing wind from passing through, thereby having good windproof and warmth retention properties. Multiple micropores are arranged inside the base material layer 1 and the anti-static and flame-retardant layer 2 to enhance the breathability of the fabric and provide good breathable and moisture-wicking properties.

[0028] A short pile layer is provided on the lower surface of the moisture-permeable inner layer 4. The moisture-permeable inner layer 4 is woven from yarns with good moisture-conducting properties, such as cotton, linen, kapok, etc., to ensure that the composite fabric has a good skin-friendly feel. At the same time, a short pile layer is provided on the lower surface of the moisture-permeable inner layer 4, and the pile layer is formed by sanding the surface of the moisture-permeable inner layer 4, which can make the fabric soft, comfortable, and rich in texture, thereby improving the wearing comfort of the moisture-permeable inner layer 4 and at the same time improving the thermal insulation effect of the composite fabric.

[0029] Implementation scheme: When in use, the base material layer 1 is prepared by spinning and cross-weaving the warp yarn 101 and the weft yarn 102. The warp yarn 101 adopts a blend of high-strength and tough nylon fiber and polyurethane fiber, and the weft yarn 102 adopts a blend of moisture-absorbing and breathable cotton fiber and polyurethane fiber, so that the fabric has excellent properties such as high strength and toughness, good moisture absorption and breathability, and good weather resistance, thereby improving the service life of the fabric. The anti-static flame-retardant layer 2 composed of conductive fiber filaments 201, glass fiber 202 and polyester fiber 203 increases the anti-static property of the fabric through the conductive fiber filaments 201, which can eliminate the harm of static electricity to the human body and The uncomfortable feeling caused by static electricity when putting on and taking off can be eliminated, and the situation of clothes sticking to the body and being tangled caused by static electricity can be eliminated. The glass fiber 202 and the polyester fiber 203 make the fabric have the characteristics of high temperature resistance and good flame retardant effect. The waterproof and breathable layer 3 made of PTFE membrane material has excellent waterproof and moisture permeability functions, and wind cannot penetrate, so it has good windproof and warmth retention. The moisture-permeable inner layer 4 is woven with yarn with good moisture-conducting performance. At the same time, a short pile layer is arranged on the lower surface of the moisture-permeable inner layer 4, which can make the fabric soft, comfortable and rich in texture, improve the wearing comfort of the fabric, and have good thermal insulation effect and moisture-conducting performance.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0031] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
