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 mosquitoes’ heads, antennae and mouths, and analyzed how they bite people. Next, they used a computer model to find out what characteristics the fabric should have that would prevent the insect’s proboscis from reaching human skin.
First, they experimented with the thickness of the pores and the thickness of the material. The blood tank was covered from mosquitoes with plastic sheets of varying density and porosity. Next, they selected a fabric that matched the characteristics of the most successful sample and tested them, too. Finally, they made a set of underwear and outerwear from the optimal fabric and tested them on volunteers.
According to the researchers, the test on the volunteers showed that such clothes can prevent 100% of bites. The test subjects wearing the new T-shirts and vests were kept in a cell with 200 hungry mosquitoes. After the first test, the mosquitoes were able to bite the fabric in the shoulders, where it stretched noticeably, reducing the density. The second version of the T-shirt eliminated this drawback by increasing the density in the areas where the fabric would stretch, thus achieving complete protection.
The American company Vector Textiles has already obtained the necessary patents and plans to commercially produce similar garments. The plan is to create a wide range of clothing made of such fabric so that a complete outfit protecting against mosquitoes can be assembled.
