Problems solved by technology

Among them, the fiber coating and dipping process is relatively simple to process, but the persistence of the mosquito repellent effect is poor; the persistence of the mosquito repellent effect of the fiber produced by the blend spinning process is better than that of the coating and dipping process, and the requirements for equipment are lower, but due to the higher spinning temperature, Mosquito repellants are easy to volatilize or decompose, which affects the mosquito repellent effect of the product, so the blend spinning process has higher requirements on the boiling point of the mosquito repellent; the compound spinning process has a long retention time of the mosquito repellent effect and a wide range of mosquito repellent choices. characteristics, but special composite spinning equipment is required, and the mosquito repellent effect is not ideal

Abstract

The invention discloses a preparation method of intelligent surface mosquito-repellent polyester fiber for a mosquito net. The preparation method comprises the following steps: performing etching reduction treatment on polyester fiber; preparing mosquito-repellent polyester fiber from a mosquito repellent by a block copolymer disperse coating method so that traditional polyester fiber becomes a high-performance spinning intelligent material and has different responsiveness to different chemical environments to finally realize a lasting mosquito killing effect of polyester filament. The mosquito-repellent polyester fiber for the mosquito net prepared by the method disclosed by the invention is scientific and technological polyester chemical fiber filament, and the mosquito repellent is uniformly distributed in the fiber surface; the mosquito-repellent polyester fiber offers different intelligent responses under the effect of specific auxiliaries and can be stored and used for long time; and moreover, the mosquito-repellent polyester fiber has the advantages of high mosquito-repellent efficiency, long duration and low toxicity and is relatively widely applicable to house materials.

Description

technical field [0001] The invention belongs to the field of novel functional intelligent fibers, and in particular relates to a preparation method of an intelligent surface mosquito-repelling polyester fiber for mosquito nets. Background technique [0002] Insecticide-treated bed nets are considered by the World Health Organization to be the most effective means of controlling insect-borne diseases, especially malaria, and insecticide-treated bed nets are becoming increasingly important in the control and prevention of diseases like malaria . [0003] In the prior art, there are many ways to drive and kill mosquitoes, including drug killing, odor fumigation, ultraviolet light trapping, etc. Many kinds of mosquito repellent products have been developed in the market, and mosquito repellent fiber is one of them. The processing method of mosquito fiber is the same as the traditional aromatic fiber processing technology, including fiber coating and dipping technology, blended ...
