Detailed Description
The utility model will now be further described with reference to the drawings and detailed description.
The embodiment of the utility model comprises the following steps:
referring to fig. 1 to 8, a novel elastic waistline comprises an upper elastic non-woven fabric 1, a lower elastic non-woven fabric 2 and an elastic rubber layer 3 clamped between the upper elastic non-woven fabric 1 and the lower elastic non-woven fabric 2, wherein the upper elastic non-woven fabric 1 and the lower elastic non-woven fabric 2 are fixedly connected through hot melt adhesive or ultrasonic welding, the upper elastic non-woven fabric 1 sequentially comprises a first non-woven fabric layer 4, a first elastic layer 5, a first breathable layer 6 and a second non-woven fabric layer 7 from top to bottom, and the lower elastic non-woven fabric 2 sequentially comprises a third non-woven fabric layer 8, a second elastic layer 9, a second breathable layer 10 and a skin-friendly layer 11 from top to bottom.
The first elastic layer 5 is formed by alternately knitting a first warp yarn 51 and a first weft yarn 52, the first warp yarn 51 and the first weft yarn 52 both comprise a first yarn core and a first cladding yarn 12 cladding the outside of the first yarn core, the first yarn core is formed by twisting spandex fibers 13 and cotton fibers 14, the first cladding yarn 12 is formed by twisting antibacterial fibers, the antibacterial fibers are any one of chitosan fibers, bamboo fibers and silver fibers, and the first cladding yarn of the embodiment is bamboo fibers. The spandex fiber has soft and smooth hand feeling, good elasticity and good shape retention; the cotton fiber is breathable and soft; the bamboo fiber not only has the characteristics of good air permeability, stronger wear resistance, good dyeing property and the like, but also has the functions of natural antibiosis, bacteriostasis, mite removal, deodorization and the like, combines the characteristics of the various fibers, and endows the first elastic layer with good elasticity, antibiosis, bacteriostasis and softness and air permeability.
The second elastic layer 9 is formed by alternately weaving second warp yarns 91 and second weft yarns 92, each of the second warp yarns and the second weft yarns comprises a second yarn core and second cladding yarns 15 cladding the second yarn core, the second yarn core is formed by twisting polyester fibers 16 and activated carbon fibers 17, and the second cladding yarns 15 are formed by twisting silver fibers.
