Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-2, a blended and textured yarn is formed by blending a plurality of fibers made of different materials, and comprises a core layer 1, a winding layer 2, a middle layer 3 and an outer layer 4 which are sequentially arranged from inside to outside, wherein the core layer 1 is arranged at the center of the blended and textured yarn, and the other three layers are arranged on the outer side of the core layer 1 in a concentric circle manner.

The core layer 1 comprises a core yarn 11, the core yarn 11 is a 20D spandex yarn, and a single spandex yarn or a plurality of spandex yarns can be selected as the core yarn 11 according to the actual situation of manufacturing the fabric. The 20D spandex yarn is fine, high in breaking elongation and good in elasticity, but the initial modulus of the spandex is low, so that the spandex yarn is soft and low in bending rigidity, but the spandex yarn needs to have high bending rigidity as a yarn for producing a body skeleton, a stiff textile fabric and the like, and therefore the winding layer 2 is arranged on the outer side of the core layer 1.

The winding layer 2 is the conductive fiber 21, the conductive fiber 21 is a fiber formed by an organic polymer in which metal micro powder is discontinuously dispersed, and the metal micro powder in the conductive fiber 21 can leak and disperse static electricity generated by the yarn, thereby being beneficial to effectively preventing local accumulation of static electricity and further eliminating the static electricity phenomenon of the yarn.

The conductive fiber 21 is spirally wrapped on the periphery of the core layer 1, and the wrapping interval of the conductive fiber 21 is 0.1-0.2cm. The conductive fiber 21 has no elasticity, so a certain distance is arranged during wrapping, and the outer side of the spandex filament can be wrapped under the condition that the elasticity of the spandex filament in the using process is not influenced; and the wrapping interval is controlled to be within 0.2cm so that the core wire 11 is wrapped with at least five turns of the conductive fiber 21 per cm, contributing to increase in bending rigidity of the core wire 11.

If only the core layer 1 and the winding layer 2 are provided, spandex exposure occurs in the yarn, and the yarn density is too low to facilitate knitting, so that the intermediate layer 3 is provided at the periphery of the winding layer 2, and the intermediate layer 33 includes a plurality of elastic yarns 31 uniformly distributed at the periphery of the winding layer 2.

The elastic yarns 31 are arranged in parallel in the longitudinal direction of the fiber, the arrangement direction of the core yarn 11 is the same as that of the elastic yarns 31, and the elastic yarns 31 are 70D/36FDTY drawn textured yarns. The linear density of the elastic yarns 31 of 70D/36F is 70D, 36 fibers are arranged in each group of elastic yarns 31, the fineness of the DTY yarn of 70D is moderate, the number of the fibers is large, and the core layer 1 and the winding layer 2 can be completely covered inside the DTY yarn. The elastic yarn 31 has good elasticity, the arrangement direction of the elastic yarn is consistent with that of the core yarn 11, the breaking specific stress of the yarn is increased on the basis of increasing the yarn elasticity, and the tensile resistance of the yarn is increased.

The DTY draw textured yarn has higher strength and higher initial modulus, thus increasing the bending stiffness of the yarn. Meanwhile, the DTY stretch textured yarn has the fluffiness and good elasticity of the textured yarn, so that the yarn feels plump and comfortable.

The elastic yarn 31 is not twisted during bundling, so an outer layer 4 is required to be disposed on the middle layer 33 for fixing the elastic yarn 31 to prevent the elastic yarn 31 from being loosened and hooked. The outer layer 4 is composed of a wrapping yarn 41, and the intermediate layer 3 is wrapped and fixed by the wrapping yarn 41. The wrapping interval of the wrapped yarn 41 is 0-0.1cm, is smaller than that of the winding layer 2, and is relatively tight in wrapping, so that the bending rigidity of the yarn can be increased, and the risk that the elastic yarn 31 fiber bundle is easy to hook can be reduced.

The fasciated yarn 41 is a cotton/polylactic acid fiber blended yarn, wherein the blending ratio of the cotton fiber to the polylactic acid fiber is 1. The polylactic acid fiber is made from agricultural products containing starch. After lactic acid is formed by fermentation, the fiber is prepared by polycondensation and melt spinning, is a semi-synthetic fiber, has good natural degradation performance, and has high initial modulus and stable size, so that the bending rigidity of the yarn can be increased. The cotton fiber has high strength and good air permeability, so that the cotton fiber and the polylactic acid fiber are blended and wound on the outermost layer of the yarn, the hand feeling of the yarn is improved, and the moisture absorption of the yarn is increased.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
