Description

Nylon covered yarn with radiation protection function

Technical Field

The utility model relates to the technical field of textile yarns, in particular to a polyamide covered yarn with a radiation-proof function.

Background

The covered yarn is also called wrapping yarn, and is a yarn with a novel structure, which takes filament or short fiber as a yarn core, is wrapped with another filament or short fiber yarn strip, and the wrapped yarn covers the core yarn in a spiral mode. The covering yarn is mainly used for knitted fabrics requiring high elasticity, is partially used for woven fabrics, is ideal yarn of high-grade thin wool, linen fabrics, jacquard double-layer weft knitted fabrics, warp knitted fabrics and the like, can be spun for thick and thin yarns, is mostly elastic yarn and is used for weaving tight sports clothes, such as swimwear, ski wear, underwear and the like.

The nylon covered yarn is a common covered yarn at present. At present, people have higher and higher requirements on clothes, and the clothes do not only seek a warm-keeping effect, but also have higher requirements on the functions of wear resistance, antibiosis, static resistance and the like. The functions of the existing nylon covered yarn are not improved well, so most garment manufacturers improve the post-treatment process of the fabric to add more functions to the fabric. However, the post-treatment process of the fabric is time-consuming, the overall appearance and hand feeling of the fabric are affected to a certain extent, and the health of a wearer may be affected by using excessive finishing aids for the fabric.

Detailed Description

In order that those skilled in the art will better understand the technical solution of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings and embodiments.

The polyamide covered yarn with the radiation protection function shown in fig. 1-2 comprises a main yarn 1 consisting of two polyether ester fiber yarns 11, and a cuprammonium fiber yarn 2 and a polyamide covered yarn 3 which are twisted and wound outside the main yarn 1. The cross section of the polyether ester fiber yarn 11 is triangular, and a metal fiber yarn 12 is arranged inside the polyether ester fiber yarn 11. The polyether ester fiber yarn 11 is generally used as a raw material of simulation silk and high-grade clothing fabric, has excellent mildew resistance, aging resistance, light resistance and wear resistance and good hand feeling, and the metal fiber yarn 12 is added in the production of the polyether ester fiber yarn, so that the polyether ester fiber yarn 11 has a good radiation protection function. The metal fiber wires 12 are stainless steel fiber wires, copper fiber wires or silver-plated fiber wires, and can be selected according to actual use requirements, so that the polyether ester fiber wires 11 have the radiation protection function.

The nylon covered yarn 3 comprises nylon yarn 31 and a nano silver paste layer 32 sprayed outside the nylon yarn 31. The nano silver paste layer 32 contains silver ions which have strong oxidizing property and can strongly attract sulfydryl on protease in the bacteria and rapidly combine with the sulfydryl to make the protease lose activity, so that the bacteria die. When the bacteria are killed by the silver ions, the silver ions are dissociated from the bacterial corpses and then contact with other bacterial colonies, and the process is carried out repeatedly, so that the fabric has the continuous sterilization and antibiosis effects. Meanwhile, the nano silver paste layer 32 also enables the nylon coated yarn 3 to have the radiation-proof effect. The cuprammonium rayon 2 is prepared by dissolving natural cellulose raw materials such as cotton linters and the like in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to prepare spinning solution, decomposing cuprammonium rayon molecular chemicals in a coagulating bath to regenerate cellulose, and post-processing the generated hydrated cellulose. The fabric made of the cuprammonium rayon 2 is fresh and cool, has good hygroscopicity, has extremely drape feeling and has the performance similar to silk. The copper ammonia fiber yarn 2 and the nylon covered yarn 3 are arranged outside the main yarn 1, so that the nylon covered yarn is comfortable in overall hand feeling and can keep good radiation resistance.

The cross section of the polyether ester fiber yarn 11 is preferably in an isosceles triangle shape, two polyether ester fiber yarns 11 can form the main yarn 1 with a diamond or square cross section, so that the overall appearance of the nylon covered yarn is unique, and the woven fabric can have unique texture. The breaking strength of the main yarn 1 is 2.9-5.5cN/dtex in dry and wet states, the elongation at break is 33-37% in dry and wet states, and the main yarn has better breaking resistance. The fineness of the copper ammonia fiber yarn 2 is 38.5-41.3dtex, the fineness of the nylon coated yarn 3 is 48.8-52.6dtex, and the fineness of the polyether ester fiber yarn 11 is 42.2-43.7 dtex. The fineness of the polyether ester fiber yarn 11, the copper ammonia fiber yarn 2 and the nylon covered yarn 3 is close to each other, the smooth handfeel of the handfeel copper ammonia fiber yarn 2 and the nylon covered yarn 3 is kept in the nylon covered yarn, the good radiation protection effect is guaranteed, after the nylon covered yarn is woven into the fabric, after-finishing treatment is not needed, and the nylon covered yarn is healthier and more environment-friendly.
