Problems solved by technology

Although there are many kinds of anti-mite agents or anti-mite drugs, many anti-mite agents commonly used in daily life have the characteristics of low melting point, low boiling point, volatile and easy to decompose at high temperature, so blending and melt spinning can be selected. There are not many types of anti-mite agents
[0004] Sinopec Yizheng Chemical Fiber Co., Ltd. applied for the patent "Production Method of Anti-mite Polyester Hollow Fiber" (Xu Yinbao et al., Patent No. CN1552962, published in December 2004), combining anti-mite agent with hollow fiber finishing agent, penetrating agent, etc. Parts are mixed according to a certain ratio, and formulated into a stable working solution containing 5-50% anti-mite agent, and the working solution is attached to the hollow fiber by immersion, spraying, coating, spraying and other methods, combined with the oiling process , and then heat-setting and other treatments, the prepared anti-mite hollow fiber, but because the anti-mite agent is attached to the hollow fiber, its washing resistance is not very good

Abstract

The invention relates to an anti-acarid polyester fiber which is characterized by comprising 1-5% by weight of anti-acarid powder, wherein the anti-acarid powder is prepared from a fenbutatin oxide solution and polyaspartic acid under the catalysis of acetic acid. The invention further relates to a preparation method of the anti-acarid polyester fiber. The anti-acarid polyester fiber has the advantages of good anti-acarid effect and good water washing resistance.

Description

technical field [0001] The invention relates to an anti-mite polyester fiber, in particular to an anti-mite polyester fiber and a preparation method thereof. Background technique [0002] There are more than 50,000 species of mites found in the world, second only to insects. Many species are related to medicine. In recent years, it has been found that mites are very closely related to human health, such as leather mites, chiggers, scabies, demodex, acaroid mites, house dust mites, and pupa mites, which can bite people and suck blood, damage the skin, and cause "rosacea" or demodex acariasis, allergies, urinary tract acariasis, pulmonary acariasis, intestinal acariasis and scabies, seriously endangering human health. In the prior art, people generally use some anti-mite agents to post-treat the fibers or fabrics so that the surface of the fibers or fabrics has anti-mite function. In this method, the anti-mite agents or anti-mite drugs are only attached to the fiber surface ...
