Description
Technical Field
The invention relates to the technical field of textile materials, in particular to an anti-mosquito fabric and a preparation method thereof.
Background
In summer, people's daily activities often can receive the serious influence of mosquito. Because the mosquito net has no mosquito repelling function, when sleeping at night, mosquitoes fly into the mosquito net to bite the human body, so that people cannot fall asleep; because the clothes have no mosquito repellent function, a human body can be bitten by mosquitoes continuously, and the work and the life of the human body are seriously influenced. Additionally, mosquitoes can transmit diseases, and different species of mosquitoes can transmit different diseases. Recently, epidemic diseases such as Japanese encephalitis (abbreviated as "Japanese encephalitis") and dengue fever in parts of China have prevailed, and the transmission routes of the diseases are mainly through mosquitoes. Mosquitoes are a very common harmful insect in summer and autumn, and are harmful to human bodies in that they bite sick animals or humans and then infect pathogens to healthy people.
The anti-mosquito fabric produced by the prior art mostly prevents mosquitoes by adding various mosquito killing substances or mosquito repelling substances, has good anti-mosquito effect, but has two serious defects, namely, the additive with good mosquito killing effect has certain damage to human bodies, the mosquito killing effect which is harmless to human bodies is poor, and the anti-mosquito substance is quickly lost and cannot be endured in the washing and using processes.
