Problems solved by technology

[0004] However, fibers with antibacterial and anti-mite functions are rare so far
Chinese patent application CN103882543A discloses a polyester fiber with antibacterial and anti-mite properties, in which the anti-bacterial and anti-mite agent is a powder of 300 nanometers, but its active ingredients are not disclosed
However, like other organic antibacterial agents and anti-mite agents, eugenol or isoeugenol has poor heat resistance and begins to volatilize in large quantities at 100°C, so it is impossible to prepare antibacterial agents containing eugenol or isoeugenol by melt spinning. Anti-mite fiber

Abstract

The invention relates to an anti bacterial anti mite fiber and preparation method thereof, the anti bacterial anti mite fiber is prepared by adding through a polymer an organic anti mite agent eugenol and / or ISO eugenol formulated with an inorganic anti bacterial agent zinc oxide and preparing into an anti bacterial anti mite agent, after melting, and spinning and being prepared. The method works by firstly mixing the organic anti mite agent eugenol and / or ISO eugenol with the inorganic anti bacterial agent zinc oxide, after refining with a ball crusher, and sieving to obtain a formulated anti bacterial anti mite powder material, then using a surface treatment agent to surface coat the formulated anti bacterial anti mite powder material; then adopting a direct append method, the surface coated and formulated anti bacterial anti mite powder material being evenly mixed with a polymer, after melting, and spinning to prepare into the anti bacterial anti mite fiber; or adopting a masterbatch method, the surface coated and formulated anti bacterial anti mite powder material being melted with a polymer and mixed together to prepare into an anti bacterial anti mite master batch, then the anti bacterial anti mite master batch being evenly mixed with a polymer, after melting, and spinning to prepare into a fiber with a long period anti bacterial anti mite effect.

Description

technical field [0001] The invention belongs to the technical field of fiber and fabric manufacture, and in particular relates to an antibacterial and anti-mite fiber and its preparation. Background technique [0002] With the improvement of living standards, people pay more and more attention to health. Clothes, quilts, carpets, cushions and other household textile products are ideal places for the proliferation of pathogenic microorganisms such as Staphylococcus aureus, Escherichia coli, Candida albicans and mites. Among them, Staphylococcus aureus, Escherichia coli, and Candida albicans can cause diseases such as pneumonia, gastroenteritis, and dermatitis; mites not only transmit bacteria and viruses themselves, but also their secretions, metabolites, and dead worms are highly toxic. It can cause allergic rhinitis, infant eczema and chronic urticaria, and even bronchial asthma and other diseases. Therefore, endowing fibers with antibacterial and anti-mite properties for...
