Abstract

The invention relates to the field of functional textiles, and particularly relates to an anti-mosquito sustained-release cloth finishing method suitable for textile fabrics. The anti-mosquito agent microcapsules are attached to the fabric by a fixing agent, then cross-linked by a crosslinking agent and dehydrated and dried to directly obtain anti-mosquito sustained-release cloth without roasting; the fixing agent is polyvinyl alcohol or a modified polyvinyl alcohol compound; and the crosslinking agent is boric acid. The finishing method is simple, short in flow, easy to operate and low in cost. The finished anti-mosquito sustained-release cloth has a quick and efficient killing effect on mosquitoes and realizes a good mosquito repelling effect. After anti-mosquito finishing, the fabric is safe and harmless to a human body, and the appearance and physical index are not influenced.

Description

technical field [0001] The invention relates to the field of functional textiles, and relates to a mosquito-proof finishing method suitable for textile fabrics. Background technique [0002] Humans have suffered from mosquito bites for a long time, which not only cause itching and pain, but also mosquitoes, as vectors, can infect many diseases such as dengue fever, malaria, flukes, lymphatic filariasis, etc., posing a serious threat to human life and health. The research report of the World Health Organization clearly pointed out that among all diseases transmitted by pests, mosquitoes bear the brunt, so mosquito repellent has always been a matter of great concern to people. [0003] In the typical method that has been invented, the patent "anti-mosquito finishing agent and its preparation method and its application in anti-mosquito fabrics" is to attach insecticides to cyclodextrin compounds, and then attach them to the cloth. The disadvantage of this method is that the ra...
