Abstract
The invention provides a copper ammonia fiber fabric and a preparation method thereof, which comprises the steps of firstly preparing modified copper ammonia fibers by using cotton linter natural cellulose, a concentrated ammonia solution of a copper compound and gamma-aminopropyltriethoxysilane modified nano-alumina as raw materials, then forming mixed filaments I by using the modified copper ammonia fibers, methacryloxypropyltrimethoxysilane modified superfine polyamide fibers and a water-soluble vinylon fiber network, then forming mixed filaments II by using the modified copper ammonia fibers and the superfine polyester fiber network, finally weaving the mixed filaments I and the mixed filaments II into warps and wefts by using a loom to obtain a fabric blank, and removing the water-soluble vinylon fibers by vacuum heating and finishing to obtain the copper ammonia fiber fabric which has excellent moisture absorption and quick drying performance and good mechanical property.
Description
Technical Field
The invention relates to the technical field of fabric spinning, in particular to a copper ammonia fiber fabric and a preparation method thereof.
Background
Along with the improvement of production development and living standard, the requirement of people on the comfort of clothes is higher and higher, and the sports clothes are one of clothes which are rather popular with people. For sports clothes, the quick drying performance is particularly important, and the clothes are required to have no skin sticking feeling even if sweat streams down.
A microclimate environment is formed between the skin of a human body and clothes, and for sports clothes, the aim of people is to reduce the moisture content of the microclimate environment as much as possible, so that sweat on the surface of the human body can be rapidly diffused through the clothes and evaporated into the air instead of continuously staying on the skin, and the clothes are kept dry and comfortable, so that people feel comfortable. The sports brands on the market at present mostly adopt water repellent chemical fibers, particularly polyester, polypropylene and the like, and the chemical fiber fabric can absorb moisture and perspire, and mainly has the advantages that after the chemical fiber fabric absorbs sweat, the diffusion speed of the sweat is high, and the sweat can be rapidly evaporated on the other side of the fabric. However, chemical fibers generally have problems such as poor air permeability and easy generation of static electricity, or poor light and heat resistance and poor wearing experience.
In natural fibers, cotton and wool feel comfortable, the moisture absorption performance is good, the wearing comfort is good, but when a human body sweats in a large amount, due to the fact that the hydrogen bond acting force between water molecules in the sweat and hydrophilic groups of the natural fibers is strong, the water molecules are not easy to separate from the fibers, the fibers expand after moisture absorption to block air holes, and the quick drying performance of the fabric is poor. Although the moisture absorption performance of the cotton fiber is very good, the moisture release speed of the cotton fiber is very slow, and the diffusion speed of sweat is also slow, so that the sweat is easy to concentrate. Once a person sweats a lot, the cotton fiber has a serious wet feeling after absorbing sweat, and is difficult to stick on the body. The scale layer structure on the surface of the wool fiber enables the wool fabric to be naturally hydrophobic, the water absorption capacity of the wool fabric is hindered, the moisture absorption and sweat releasing rate is low, and people can feel sultry and uncomfortable after a large amount of movement of a human body. And although the synthetic fiber fabrics such as terylene and chinlon have good quick-drying property, the water absorption is poor, so that the wearing comfort is greatly reduced.
The copper ammonia fiber is a regenerated cellulose fiber, which 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 copper ammonia cellulose molecular chemicals in a coagulating bath to regenerate cellulose and post-processing the generated hydrated cellulose. The section of the cuprammonium rayon is round, the cuprammonium rayon has no skin-core structure, the fiber can bear high stretching, and the prepared monofilament is thin, so that the fabric is soft in hand feeling, soft in luster and real in silk feeling. The cuprammonium fiber has the advantages of moisture absorption, air permeability, good moisture absorption and release, comfortable wearing and no sultry, and is an ideal raw material for quick-drying textiles.
However, copper ammonia fibers also have a number of disadvantages:
1. the price is expensive;
2. the wet strength is lower than that of cotton fiber, the moisture absorption is strong, the shrinkage rate is large, and fiber breakage is easy to occur in the production process;
3. the cuprammonium fibers are easy to swell when meeting water, the cloth cover becomes hard, and the fibers are easy to scratch in the production process, so that the strength of the product is influenced;
4. copper ammonia fiber has poor alkali resistance, and the influence of alkali on the fiber should be particularly noticed in the production process;
5. copper ammonia fibers have poor resistance to chlorine-containing bleaching agents, hydrogen peroxide.
Patent CN102021710B discloses a method for producing a copper ammonia silk textile product, which comprises the steps of respectively winding 120 denier copper ammonia silk filament and 14.6tex copper ammonia silk fiber blended yarn into cone yarn, and then carrying out bleaching, pickling, deoxidizing, yarn dyeing and soaping treatment; then, the copper ammonia fiber blended yarns are used as warp yarns, and the copper ammonia filaments are used as weft yarns, and are woven into grey cloth; and then, after singeing, desizing and softening the grey cloth, carrying out post-treatment on the grey cloth to obtain the copper ammonia wire textile product. However, sodium hydroxide 1-1.6 ml/L and 27.5 wt% hydrogen peroxide in the scouring and bleaching solution cause great damage to copper ammonia fibers, and the mechanical property of the obtained product is poor.
Disclosure of Invention
The invention aims to provide a copper ammonia fiber fabric and a preparation method thereof, and the copper ammonia fiber fabric has excellent moisture absorption and quick drying performance and good mechanical properties.
In order to achieve the purpose, the invention is realized by the following scheme:
a preparation method of a copper ammonia fiber fabric comprises the following specific steps:
(1) firstly, preparing modified cuprammonium fibers by using cotton linter natural cellulose, a concentrated ammonia solution of a copper compound and gamma-aminopropyltriethoxysilane modified nano-alumina as raw materials;
(2) and then mixing the components in a mass ratio of 1: 0.2-0.3: 0.03-0.04 of modified cuprammonium fibers, methacryloxypropyltrimethoxysilane modified superfine polyamide fibers and a water-soluble vinylon fiber network to form a mixed filament I;
(3) then, mixing the components in a mass ratio of 1: 0.1-0.2 of modified cuprammonium fibers and a superfine polyester fiber network form a mixed filament II;
(4) finally, weaving the mixed filament I and the mixed filament II into warp yarns and weft yarns respectively, obtaining a fabric blank by using a loom, and performing vacuum heating finishing to remove the water-soluble vinylon fibers to obtain the copper ammonia fiber fabric;
