Copper ammonia fiber fabric and preparation method thereof

Abstract

The present invention provides a copper ammonia fiber fabric and a preparation method thereof. The method comprises the steps of firstly preparing cotton linter natural cellulose, a copper compound concentrated ammonia solution, gamma-aminopropyltriethoxy silane modified nano alumina as raw materials into modified copper ammonia fibers, then forming mixed filaments I by the modified copper ammoniafibers, methyl acryloxypropyl trimethoxy silane modified superfine polyamide fibers and a water-soluble vinylon fiber network, then forming mixed filaments II by the modified copper ammonia fibers and a superfine polyester fiber network, and finally weaving the mixed filaments I and the mixed filaments II into warps and wefts by using a loom to obtain a grey fabric, and performing vacuum heatingand finishing to remove water-soluble vinylon fibers so as to obtain the copper ammonia fiber fabric. The copper ammonia fiber fabric has excellent moisture-absorbing and quick-drying performance andgood mechanical performance.

Description

technical field [0001] The invention relates to the technical field of fabric textiles, in particular to a cupro ammonia fiber fabric and a preparation method thereof. Background technique [0002] With the development of production and the improvement of living standards, people have higher and higher requirements for the comfort of clothing, and sportswear is one of the most popular clothing. For sportswear, quick-drying performance is particularly important, and it is required that the clothing will not feel sticky to the skin even if it is sweating. [0003] There is a microclimate environment between the human skin and clothes. For sportswear, how to reduce the water vapor content of this microclimate environment as much as possible, so that the sweat on the surface of the human body can quickly diffuse through the clothing and evaporate into the air instead of Continue to stay on the skin, and keep the clothing dry and comfortable, has always been the goal of people's...

AI Technical Summary

Problems solved by technology

[0007] 1. The price is relatively expensive;

[0008] 2. The wet strength is lower than that of cotton fiber, with strong hygroscopicity and large shrinkage, and fiber breakage is easy to occur during the production process;

[0009] 3. Cupro ammonia fiber is easy to swell when it meets water, and the cloth surface becomes hard, which is easy to cause fiber scratches during the production process, thereby affecting the product strength;

[0010] 4. Cupro ammonia fiber has poor alkali resistance, and special attention should be paid to the influence of alkali on the fiber during the production process;

[0011] 5. Cupro ammonia fiber has poor resistance to chlorine bleach and hydrogen peroxide

However, the boiling and bleaching solution contains 1-1.6ml / L of sodium hydroxide and 27.5wt% hydrogen peroxide, which will cause great damage to the cupro ammonia fiber, and the mechanical properties of the obtained product are relatively poor.
