Description

Spandex fabric

Technical Field

The utility model relates to the technical field of textile fabrics, in particular to a spandex fabric.

Background

Spandex is an abbreviation for polyurethane fiber, which is an elastic fiber. At present, most of fabrics are made of natural fibers and artificial fibers. Cotton, for example, is a natural fiber, which has good air permeability and moisture absorption properties, but has poor elasticity and is easy to deform. The artificial fiber is one kind of fiber synthesized manually according to the requirement, and has solved some of the disadvantages of natural fiber. Spandex, one of the polyester-based fibers of artificial chemical synthetic fibers, is called elastic fiber because of its excellent elasticity. The spandex with different proportions is generally mixed into the clothing fabric to achieve the effect of increasing elasticity and comfort, and the clothing fabric has wide application range.

The spandex fabric has the advantages of high elasticity, large stretching property, good shape retention, no wrinkling and the like, but the single-performance spandex fabric has weak market competitiveness and needs to be continuously improved. And the spandex fabric has the problems of poor hygroscopicity, poor heat resistance and the like. Therefore, we invented a spandex fabric.

As shown in fig. 1-2, a spandex fabric comprises a spandex base layer 1; further comprises a moisture-absorbing and breathable layer 2 and a heat-resistant layer 3; the moisture absorption breathable layers 2 are arranged on two sides of the spandex base layer 1, and a heat-resistant layer 3 is arranged on the outer surface of the moisture absorption breathable layer 2 on one side; the outer surface of the heat-resistant layer 3 is coated with a layer of ultraviolet light resistant polyester film; the polyurethane base layer 1 is formed by weaving polyurethane core-spun yarns, the heat-resistant layer 3 is formed by weaving heat-resistant polyurethane fibers, and the heat-resistant polyurethane fibers comprise heat-resistant core yarns 31 and hot-melt skins 32.

Specifically, the spandex base layer 1 is formed by weaving spandex core-spun yarns, the spandex core-spun yarns are formed by taking spandex filaments as an axial core and wrapping a layer of uniform cotton fibers outside the axial core to twist, the spandex core-spun yarns have excellent elasticity, good hygroscopicity and air permeability, static electricity cannot occur on the surfaces of the fibers, dust collection is not easy to perform on clothes made of the core-spun yarns, and the dyeing property is good.

Further, the moisture-absorbing and breathable layer 2 is formed by weaving bamboo fiber yarns and profiled polyester fiber yarns. The bamboo fiber is known as breathing fiber, has no moisture absorption and sweat release capability inferior to that of pure cotton, has the functions of mildew resistance and health care, and meets the various demands of people on clothing fabrics. The moisture absorption breathable layer 2 woven by the bamboo fiber yarn and the profiled polyester fiber yarn has the advantages of natural bacteriostasis, moisture absorption breathable performance and good strength. Still further, the fiber section of the profiled polyester fiber yarn is cross-shaped, and has excellent moisture absorption effect.

Further, the heat-resistant layer 3 is woven from heat-resistant spandex fibers including a heat-resistant core yarn 31 and a hot-melt sheath 32. Preferably, the heat-resistant core yarn 31 is a heat-resistant spandex fiber, and the heat-resistant spandex fiber is specifically obtained by spinning a spandex fiber after adding a meta-aramid fiber-producing spinning dope into a spandex fiber-producing spinning dope. Therefore, the heat-resistant spandex fiber keeps the original high elasticity and has more excellent heat resistance under the action of meta-aramid stock solution than the traditional spandex fiber. Further, the hot melt sheath 32 is a hot melt adhesive, specifically, a molten hot melt adhesive is sprayed on the surface of the heat-resistant spandex fiber before the heat-resistant spandex fiber is spun and molded. Still further, the hot melt adhesive material is polyurethane-urea, and the hot melt adhesive is convenient for the combination of the heat-resistant layer 3 and the moisture-absorbing and breathable layer 2 while not affecting the performance of the heat-resistant core yarn 31, so that the overall structure of the fabric is stable.

Still further, the ultraviolet light resistant polyester film has a thickness of 0.05mm to 0.15mm. The ultraviolet light resistant polyester film is formed by extruding and pressing polyester and ultraviolet light absorber compound master batch, and both surfaces of the ultraviolet light resistant polyester film are the ultraviolet light absorber compound master batch. Specifically, the preparation raw materials of the ultraviolet light absorber compound master batch comprise polyester chips, ultraviolet light absorbers, light stabilizers and antioxidants.
