A kind of copper ammonia fiber fabric and preparation method thereof

Abstract

The invention provides a cupro-ammonia fiber fabric and a preparation method thereof. Firstly, the raw material is made of cotton linter natural cellulose, copper compound concentrated ammonia solution, and γ-aminopropyltriethoxysilane modified nano-alumina. Then the modified cupro ammonia fiber, methacryloxypropyltrimethoxysilane modified ultrafine nylon fiber and water-soluble vinylon fiber network to form a mixed filament I, and then the modified cupro ammonia fiber The mixed filament II is formed with the superfine polyester fiber network, and finally the mixed filament I and the mixed filament II are woven into warp yarns and weft yarns respectively by a loom to obtain a fabric blank, and the water-soluble vinylon fiber is removed by vacuum heating to obtain a The cupro ammonia fiber fabric has excellent moisture absorption and quick-drying performance, and good mechanical properties.

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