Problems solved by technology

[0004] At present, all kinds of antibacterial textiles seen in the market are basically processed by three methods: one is to add antibacterial agents (often called antibacterial finishing agents) during the finishing process of fabric printing and dyeing, and then make various antibacterial textiles, This method can not only produce pure natural fiber or pure chemical synthetic fiber products, but also produce blended fiber products. It has wide adaptability, so most antibacterial textiles are produced using this method, but this method is fast to wash. The second is to add antibacterial agents to the spinning material to make antibacterial fibers, and then make various antibacterial textiles. This method is relatively complicated in technology, but the washing fastness is relatively good; Grafting to the reactive group on the surface of the fiber, for substances that do not have a reactive group, the reactive group must be introduced to make the fiber chemically modified, and then made into home textiles. This method has narrow adaptability

Abstract

The invention discloses an environment-friendly antibacterial and anti-mite fiber fabric for home textiles, and relates to the technical field of textile fabric processing. A non-release polymer antibacterial and anti-mite agent (antibacterial and anti-mite master batch) which can act on cell membranes of bacteria is adopted, the bacteria cannot breathe, and death of the bacteria is caused; and meanwhile, mites can be repelled and killed, the mites cannot survive and breed on the textiles, and the effects of excellent washability and reliable and perdurable antibacterial and anti-mite effects are achieved. The detection shows that the antibacterial rate of staphylococcus aureus, escherichia coli and candida albicans can reach 99% or above, and the repelling rate of the mites can reach 97% or above.

Description

Technical field: [0001] The invention relates to the technical field of textile fabric processing, in particular to an antibacterial and anti-mite fiber fabric for green and environment-friendly home textiles. Background technique: [0002] One-third of a person's life is spent in bed, and home textiles such as bed sheets and quilt covers are washed less often, most of which are made of natural fibers, and cotton fibers can retain a lot of water and nutrients , These provide a good environment for the growth of bacteria and mites, so the most needed function of home textile products is antibacterial and anti-mite performance. [0003] According to the mechanism and way of action, the antibacterial treatment of fibers or textiles can be divided into chemical and physical methods. Physical methods are mainly completed by blending and adding in the spinning process and immersion or adsorption in the finishing process; chemical methods are mainly completed. It is accomplished b...
