Mosquito-proof finishing agent and preparation method and its uses in mosquito-preventing fabric

Abstract

The invention provides a mosquito proof finish agent, process for preparation, and a mosquito proof fabric processed by adopting the process for preparation, wherein the mosquito proof finish agent is mainly composed of cyclodextrin compound, anophelifuge, surface activator, buffering agent, accelerant and cross linking agent, through including the anophelifuge into the cyclodextrin compound hollow chamber and then using the glyoxaline resin as the cross linking agent and then charging certain other addictive to obtain the finish agent. The solution of the mosquito proof finish agent goes through the slop padding, pre-baking and baking procedures and is dressed onto the cloth material through chemical cross linking method to obtain a mosquito proof fabric. In order to improve the mosquito proof effect, the obtained mosquito proof fabric is further dipped by the diethyltoluamide alcohol solution and is dried to complete the process. The mosquito proof fabric has the advantages of safety, long duration of mosquito proof effect and wearing comfort and can be widely applied in the process of each kind of mosquito proof fabric with good social and economy benefits.

Description

Technical field

[0001] The invention relates to the field of functional textiles, in particular to an anti-mosquito finishing agent used in fabrics and a preparation process, and a method for preparing anti-mosquito fabrics by using the above-mentioned anti-mosquito finishing agent.

Background technique

[0002] In addition to directly biting and sucking blood and harassing the peaceful working and living atmosphere, mosquitoes can also transmit a variety of serious diseases, such as malaria, dengue fever (or dengue hemorrhagic fever), Japanese encephalitis, lymphatic filariasis, yellow fever disease, equine encephalitis, etc., seriously endangering human health. According to statistics, more than 1 million people die from mosquito-borne diseases every year. Prevention and control of the spread of mosquito-borne diseases (malaria, dengue fever, Japanese encephalitis, etc.) is an important public health issue of global concern. Reducing the incidence of mosquito-borne di...
