Embodiment Construction

[0011] 1. Selection of raw materials

[0012] The core yarn is selected from PTT shape memory filament (2), which has a linear density of 22.5 dtex, a breaking strength of 3.0 cN / dtex, and a breaking elongation of 67.5%.

[0013] Outsourcing fibers are mainly cotton fibers and nylon fibers. Cotton fibers are mainly long-staple cotton, with a linear density of 1.3dtex, a breaking strength of 2.5cN / dtex, and a breaking elongation of 7.0%; nylon fibers have a linear density of 5.5dtex, a breaking strength of 5.2cN / dtex, and a breaking elongation of 35.5 %.

[0014] 2. Spinning of core-spun yarn

[0015] Cotton fibers are spun into quantitative rovings through the processes of opening and cleaning, carding, combing, drawing, and roving. On the ring spinning frame modified by the device, the roving (1) is fed from the rear roller, and the PTT shape memory is long. The silk (2) is fed from the front roller, and the cotton roving (1) and the PTT shape memory filament (2) are outpu...

Abstract

A pair of shape memory covering yarn silk stockings is formed by weaving two covering yarns which adopt PTT shape memory filament yarns (2) as core yarns and is wrapped by nylon fiber (3) and cotton fiber (1) respectively, wherein stocking toes (8), stocking soles (7) and stocking heels (6) are formed by weaving cotton fiber-PTT shape memory filament yarns formed in a manner that the cotton fiber (1) wraps the shape memory filament yarns (2), stocking surfaces (9) and stocking legs are formed by weaving nylon fiber-PTT shape memory filament yarns formed in a manner that the nylon fiber (1) wraps the shape memory filament yarns (2). The shape memory covering yarn silk stockings overcome the defects of several kinds of materials, the roughness caused by quartz fiber is avoided, the elasticity of the memory covering yarn silk stockings is higher than that of spandex covering yarns, the transparency is greatly improved, and the cost performance is high. The shape memory covering yarn silk stockings are good in elasticity, comfortable in wearing and good in air permeability, and have a shape memory function, leg lines can be more beautiful, the cost performance is high compared with silk stockings made of other materials, and the requirements of consumers can be better met.

Description

technical field [0001] The invention relates to a silk stocking, in particular to a core-spun silk stocking with good elasticity, comfortable wearing, good air permeability and shape memory function. Background technique [0002] Stockings are a woman's second skin and a must-have item for every woman. The function of stockings is not only to dress up the legs, a pair of high-quality stockings should also consider health and have excellent performance. First of all, stockings have a breathable function, which can discharge sultry moisture even in summer, allowing the skin to freely contact with the air; secondly, stockings should have high elasticity, tighten the fat on the legs, make the legs more beautiful, and effectively prevent veins Varicose; and silk stockings should have strong adhesion, closely fit with the skin; silk stockings should also be durable and not easy to snag. [0003] Existing stockings are made of nylon silk, crystal silk, core-spun silk, velvet, Lyc...
