American experts have created clothing from textile materials. It is insecticide-free and will protect you from mosquito bites, including those that carry diseases such as Zika virus, yellow fever or dengue.
The work was published in the journal Insects. Researchers at the University of North Carolina (USA) have created and tested clothing that protects against the bite of the Aedes aegypti mosquito. To do this, they used a computational model of their own design, which prevented 100 percent of bites. This was achieved thanks to accurate data on the size of the head and proboscis of Aedes aegypti.
Based on this information, the scientists calculated the size of the pores between the fibers and the thickness of the threads, and then created the appropriate tissue. To test the accuracy of their model, they ran an experiment by filling a reservoir with blood and covering it with the material described by the model. Then the mosquitoes were released, and then they counted how many of them were able to drink blood.
By the way, there are several types of fabric. One of them, for example, was very thin, less than one millimeter. Nevertheless, it consisted of very dense fibers through which insects simply could not push their proboscis. The second material had pores of medium size, so that the mosquito could not stick its head through them. And the third was with large pores, but dense enough, so the insects still could not get to the skin.
Volunteers also took part in the experiment: they wore clothes made of different types of fabric, through which mosquitoes really could not get to the body. In addition, the scientists compared the effect of their development with clothing treated with insecticides, and found that their fabric copes with bites better - by 100 percent.
Because of the similarity of Aedes aegypti to other mosquito species, the researchers believe the tissue will be effective against them as well. Therefore, the authors of the study have already created underwear, long-sleeved shirts and other clothing based on this fabric and are planning to patent the development. In their opinion, it will be useful for both the military and ordinary people.
