Description

A kind of nylon covered yarn with anti-radiation function

technical field

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

Background technique

Covered yarn, also known as wrapped yarn, is a new type of yarn. It uses filament or short fiber as the core, and wraps another filament or short fiber yarn. The wrapped yarn is spirally aligned to the core. The yarn is covered, which is characterized by uniform evenness, fullness and fullness, smooth yarn with less hairiness, high strength and less broken ends. Covered yarns are mostly used for knitted fabrics that require high elasticity, and some are used for woven fabrics. They are ideal yarns for high-grade and thin wool, hemp fabrics, jacquard double-layer weft knitted fabrics and warp knitted fabrics. All yarns can be spun, and most of them are elastic yarns, which are used to weave sports tights, such as swimming suits, ski suits, underwear, etc.

Nylon covered yarn is a common covered yarn now. At present, people's requirements for clothing are getting higher and higher, and they are no longer only pursuing thermal insulation effects, but also put forward higher requirements in terms of wear resistance, antibacterial, antistatic and other functions. The existing nylon covered yarns are not well improved in function, so most clothing manufacturers will improve the post-processing process of the fabrics to add more functions to the fabrics. However, the post-processing process of the fabric is time-consuming, which will have a certain impact on the overall appearance and feel of the fabric, and the use of too much finishing auxiliaries on the fabric may also affect the wearer's health.

SUMMARY OF THE INVENTION

The purpose of this utility model is to solve the problems in the prior art, and provide a kind of nylon covered yarn with anti-radiation function. It has a good radiation protection effect, and has a unique appearance and a good feel.

In order to achieve the above object, the technical scheme of the present utility model is:

A nylon covered yarn with anti-radiation function, comprising a main yarn composed of two polyetherester fiber filaments, cupro fiber yarns and nylon covered yarns twisted and wound outside the main yarn, the polyetherester fiber The cross section of the wire is triangular, and the polyetherester fiber wire is provided with metal fiber wire.

Preferably, two of the two polyetherester fiber filaments form a main yarn with a rhombus or square cross-section.

Preferably, the metal fibers are stainless steel fibers, copper fibers or silver-plated fibers.

Preferably, the breaking strength of the main yarn is 2.9-5.5 cN/dtex in both dry and wet states, and the elongation at break is 33-37% in both dry and wet states.

Preferably, the fineness of the cupro fiber yarn is 38.5-41.3 dtex, the fineness of the nylon covered yarn is 48.8-52.6 dtex, and the fineness of the polyetherester fiber yarn is 42.2-43.7 dtex.

The beneficial effects of the utility model are as follows: the nylon covered yarn with anti-radiation function of the present utility model comprises a main yarn composed of two polyetherester filaments and a cupro filament twisted and wound outside the main yarn and nylon covered silk; the cross-section of polyetherester fiber is triangular, and the inside of polyetherester fiber is provided with metal fiber, which can make polyetherester fiber have better radiation protection function; nylon covered The silk includes nylon silk and a nano-silver paste layer sprayed on the nylon silk. The nano-silver paste layer has silver ions, which have good antibacterial and bacteriostatic effects, and also have anti-radiation functions; the fabric made of cupro filaments is refreshing, has good hygroscopicity, has a very drapey feeling, and its performance is similar to that of silk; The cupro fiber yarn and the nylon covered yarn are arranged outside the main yarn, so that the nylon covered yarn feels comfortable as a whole, and at the same time, it can maintain good radiation protection performance.

Detailed ways

In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

As shown in Fig. 1-Fig. 2, a nylon covered yarn with anti-radiation function includes a main yarn 1 composed of two polyetherester fiber filaments 11 and a cupro fiber filament twisted and wound outside the main yarn 1 2 and nylon covered wire 3. The cross section of the polyetherester fiber filaments 11 is triangular, and metal fiber filaments 12 are arranged inside the polyetherester fiber filaments 11 . Polyetherester fiber silk 11 is generally used as a raw material for imitation silk and high-grade clothing fabrics. With the metal fiber filaments 12, the polyetherester fiber filaments 11 can have a better radiation protection function. Wherein, the metal fiber filaments 12 are stainless steel fiber filaments, copper fiber filaments or silver-plated fiber filaments, which can be selected according to actual use requirements, all of which can enable the polyetherester fiber filaments 11 to have a radiation protection function.

The nylon-coated filaments 3 include nylon filaments 31 and a nano-silver paste layer 32 sprayed outside the nylon filaments 31 . The nano-silver paste layer 32 has silver ions, and the silver ions have strong oxidizing properties, which can strongly attract the sulfhydryl groups on the protease in the bacterial body, and quickly combine with it, so that the protease loses its activity and leads to the death of the bacteria. When the bacteria are killed by silver ions, the silver ions are freed from the corpse of bacteria, and then contact with other colonies. At the same time, the nano-silver paste layer 32 also makes the nylon-coated yarn 3 have the effect of preventing radiation. Cupro fiber yarn 2 is made by dissolving natural cellulose raw materials such as cotton linters in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to prepare a spinning solution. The cellulose is produced, and the hydrated cellulose is obtained by post-processing. The fabric made of cupro filament 2 is refreshing, has good hygroscopicity, has a great drape, and its performance is similar to that of silk. The cupro fiber yarn 2 and the nylon covered yarn 3 are arranged outside the main yarn 1, so that the nylon covered yarn feels comfortable as a whole, and at the same time, it can maintain good radiation protection performance.

The cross section of the polyetherester fiber filament 11 is preferably an isosceles triangle shape, and two of the two polyetherester fiber filaments 11 can form a main yarn 1 with a diamond or square cross section, so that the overall shape of the nylon covered yarn is Unique, woven fabrics can also have unique textures. The breaking strength of the main yarn 1 is 2.9-5.5 cN/dtex in both dry and wet states, and the elongation at break is 33-37% in both dry and wet states, and has good breaking resistance. The fineness of the cupro fiber yarn 2 is 38.5-41.3 dtex, the fineness of the nylon-coated yarn 3 is 48.8-52.6 dtex, and the fineness of the polyetherester fiber yarn 11 is 42.2-43.7 dtex. The fineness of polyetherester fiber yarn 11, cupro fiber yarn 2 and nylon-coated yarn 3 are similar, and the final nylon-coated yarn retains the smooth hand feeling of cupro fiber yarn 2 and nylon-coated yarn 3, and at the same time It also ensures better radiation protection effect, and no post-finishing treatment is required after weaving into fabrics, which is more healthy and environmentally friendly.

The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
