Anti-mite antibacterial polyester staple fiber and preparation method thereof

Abstract

The invention relates to insoluble inorganic anti-mite antibacterial polyester staple fiber which is prepared from micron-scale heat accumulation anti-mite ceramic powder and silver-loaded nano titanium dioxide composite antibacterial powder through an esterification polymerization spinning mode or prepared by making the powder into masterbatch and mixing with polyether slices and spinning, wherein the micron-scale heat accumulation anti-mite ceramic powder is prepared from 2-6 parts of Tai Chi stone, 5-12 parts of boric acid, 8-30 parts of clayed soil and 3-8 parts of silicic acid by mass by grinding, tabletting, calcining and high-temperature compounding; the silver-loaded nano titanium dioxide composite antibacterial powder is prepared from 1-1.5 parts of silver nitrate and sodium chloride and 3-5 parts of metatitanic acid by mass by precipitation, suction filtration, washing, drying and calcining; the anti-mite antibacterial polyester staple fiber obtained by spinning has a relatively strong antibacterial effect on staphylococcus aureus and escherichia coli, wherein the antibacterial rate is greater than or equal to 95%, and the mite proliferation inhibition rate is greater than 92%.

Description

technical field [0001] The invention relates to an anti-mite and antibacterial polyester staple fiber and a preparation method thereof, in particular to a non-dissolving, inorganic anti-mite and antibacterial polyester staple fiber and a preparation method thereof. Background technique [0002] Mites are a kind of "miniature animals" that are not easy to see with the naked eye. There are many kinds of mites. At present, there are more than 40 kinds of mites living in the living room. The suitable living conditions for mites are the temperature of 17~30℃ and the relative humidity of 75%~80%. Mites are found in every corner of our lives. They breed on carpets, sofas, plush toys, bedding, cushions, mattresses and pillow cores, and feed on mold, human sweat, secretions, and shed skin flakes. Extremely fast, the mite can live for about four months, during which time it can produce feces 200 times its body weight and lay as many as 300 eggs. Mites themselves are not allergens, b...

Problems solved by technology

[0005] Anti-mite and antibacterial fiber products are mostly used in products that are in direct contact with the skin surface, so the safety and effectiveness of the finishing agent used and the compatibility with the fiber characteristics should be fully considered. Scientific research shows that acids, esters, alcohols, and phenols are used as The organic anti-mite and antibacterial agent as the main raw material has obvious short-term bactericidal and bacteriostatic effects, but its temperature resistance is poor, generally within 200°C, and it will melt out and precipitate after long-term use, which may irritate the skin and endanger health, such as organochlorines It will produce dioxin, a persistent pollutant poison, which will damage the liver and immune system. Pyrethroid anti-mite agents will also produce dioxin, and their anti-mite effect is not satisfactory. Organophosphorus anti-mite agents are an environmental hormone. It can cause many problems such as endocrine disorders and hormone regulation disorders.
