Problems solved by technology

[0004] However, the existing methods for preparing mosquito repellent textiles have problems such as that the mosquito repellent is easy to volatilize in large quantities during the processing, the loss is large, the mosquito repellent coating is easy to fall off, the process is complicated, the slow release effect of the mosquito repellent is poor during use, and the mosquito repellent effect is not good. ideal
And the mosquito repellants used are mostly insect repellents, pyrethroids, etc., which are highly toxic, and long-term inhalation will affect human health.

Abstract

The invention provides a mosquito-dispelling polyamide 6 fiber and a preparation method thereof. The preparation method comprises the following steps of: after adsorbing mosquito-dispelling ester to attapulgite, adding an additive and polyamide 6 resin; extruding in a double-screw extruder and granulating to prepare mosquito-dispelling polyamide 6 master batch, wherein the mosquito-dispelling polyamide master batch comprises the following materials in percentage by weight: 60-70 percent of fiber-scale polyamide 6 resin, 15-30 percent of attapulgite, 0.1-1 percent of antioxidant, 0.1-1 percent of light stabilizer 78300 and 5-15 percent of mosquito-dispelling ester, wherein the antioxidant is a composition of MD 697 and one of a hindered phenolic antioxidant, a phosphite ester antioxidant and thiodipropionate antioxidant; and performing blended spinning on polyamide 6 slices and the mosquito-dispelling polyamide 6 master batch according to the weight ratio of80-90:10-20 to prepare the mosquito-dispelling polyamide 6 fiber. The mosquito-dispelling polyamide 6 fiber has the advantages of lasting mosquito-dispelling effect, simple process, low cost, wide application and the like.

Description

technical field [0001] The invention relates to the technical field of modified fibers, in particular to a mosquito-repelling nylon 6 fiber and a preparation method thereof. Background technique [0002] Nylon 6 fiber has the characteristics of high breaking strength, excellent wear resistance, small specific gravity, good elasticity and hygroscopicity, excellent chemical stability, and anti-mold and moth resistance. Therefore, it is widely used in socks, underwear, clothing fabrics, non-woven fabrics, especially Especially in the fields of clothing, hosiery and nonwoven fabrics. With the rapid increase of domestic nylon production, the market competition for conventional products has intensified. The development of high-tech and high value-added products has become an urgent problem to be solved in the nylon industry. [0003] Preparation of textiles with mosquito repellent effect has been reported in patents, such as patents CN1468983A and CN1468984 using DEET and PP melt ...
