A kind of production method of copper ion antibacterial yarn

Abstract

The invention relates to a production method of copper ion antibacterial yarn. The tooling used includes a main cylinder capable of heating and an auxiliary cylinder, and circulation pipelines (3, 4) communicating with the main cylinder and the auxiliary cylinder. The antibacterial yarn Prepared from cellulose fibers (0), the cellulose fibers (0) in rolls or strands are placed in the main tank, characterized in that it includes the following steps: S1) alkali activation of the cellulose fibers; S2) Copper ion grafting treatment; S3) cleaning, acid adjustment, dehydration and drying; S4) mixing and weaving the cellulose fiber (0) obtained in the step 3) with ordinary fibers to prepare the copper ion antibacterial yarn Wire. The production method of the copper ion antibacterial yarn of the present invention allows copper ions to be grafted onto cellulose fibers through a grafting reaction, and the produced copper ion fibers have high washability and durable service life under specific water temperature and tooling.

Description

technical field [0001] The invention belongs to the technical field of fiber post-treatment, and in particular relates to a production method of copper ion antibacterial yarn. Background technique [0002] With the frequent occurrence of public health incidents, especially the SARS incident in 2003 and the new type of pneumonia in 2020, people are pursuing a safe and comfortable living environment. At the same time, they pay more attention to the safety and environmental protection of the use of antimicrobial products. Cellulose fiber is a natural fiber made of cotton, viscose, tencel, hemp and other materials. It has the characteristics of environmental protection, renewable, good water absorption and good comfort. It is widely used in the textile industry to make clothing, household items, Cleaning supplies, non-woven fabrics and other fields. With the improvement of consumers' demand for health, comfort and cleaning, the demand for textiles with antibacterial properties ...

AI Technical Summary

Problems solved by technology

The above antibacterial technologies all have environmental protection or safety problems: 1) Silver antibacterial agent, which is finished on textiles with carrier silver or polymer silver compound, but silver, as a heavy metal element, cannot be metabolized in the human body, and there are potential safety hazards to the human body and the environment ; 2) Copper ion antibacterial agent, finished on textiles with copper ion oxide or organic copper ion compound, both copper ion oxide and organic copper ion compound have high toxicity, and there is a safety hazard to the environment; 3) Zinc antibacterial agent, Finishing on textiles with nano-zinc oxide or organozinc compounds has poor antibacterial effect, and nano-materials or organozinc have potential safety hazards to human body and environment; Poor washing resistance on textiles, easy to dissolve, great hidden danger to health

However, the existing copper ion fibers only have chemical fibers, or the copper ions are sorted into cotton fabrics through the post-finishing process, which has the problem of poor washability

Plant fiber has the characteristics of human safety, but due to the surface polarity and internal porous structure of plant fiber, it is easy to absorb environmental moisture, resulting in strong water and hygroscopicity of plant fiber composite materials, which is conducive to the growth and reproduction of bacteria and mold, reducing the Durability and service life of plant fiber fabrics

In addition, the preparation of copper ion fibers in the prior art is a simple water boiling process, and it is generally believed that the use of boiling treatment liquid can better make copper ions adhere to the fibers
