Scientists from the University of North Carolina were able to create clothing that protects against mosquito bites but does not contain insecticides and is completely safe for the owner and pets.
To do this, they measured the size of the head, antenna, and mouth of mosquitoes and analyzed how they bite people. Next, they used a computer model to determine the characteristics of the tissue, which would not allow the proboscis of the insect to the human skin.
At first, they experimented with the thickness of the pores and the thickness of the material. The tank with blood was closed from mosquitoes with plastic sheets of different densities and porosity. Next, they picked up a fabric that corresponded to the characteristics of the most successful sample and tested them too. Finally, a set of underwear and outerwear was made from the optimal fabric and tested on volunteers.
As reported by the researchers, the test on volunteers showed that such clothing could prevent 100% of bites. Subjects in new T-shirts and vests were in a cell with 200 hungry mosquitoes. After the first test, the mosquitoes managed to bite through the tissue in the shoulders, where it was noticeably stretched, reducing the density. In the second version of the T-shirt, this drawback was eliminated by increasing the density in places where the fabric will stretch, making it possible to achieve complete protection.
The American company Vector Textiles has already received the necessary patents and plans a commercial release of such clothes. The plans are to create a wide range of clothes from such fabric so that you can assemble a full outfit that protects against mosquitoes.
