There are about 3000 different species of mosquitoes around the world, and the distribution range is very wide. Mosquitoes cause epidemic disease transmission in tropical and subtropical areas. Nowadays, people often attach a 'chemical shield' to resist the bite of mosquitoes while physically shielding (such as special protective clothing or mosquito nets). Chemical shielding generally takes two forms: natural or synthetic protective agents, for use on the skin or textiles; or insecticides, such as synthetic pyrethrin active ingredients, can be used for finishing textiles, tents, mosquito nets, sleeping bags, tent floors, and the like. At present, various methods in the market realize poor durability mosquito prevention effect, and basically have no mosquito prevention effect after being washed for a plurality of times.
