The possibility of chemically combining carboxyide repellent to cotton threads by treatment with polyacrylic acid using a radiation-chemical method was studied. After entomological and toxicological studies of 3 kinds of material, a cloth containing 20-30% carboxide and retaining repellent properties after 5 washes was selected. The control cloth impregnated with 20% water emulsion of carboxide lost its repellency by 40% after the 1st wash and completely after the 2nd wash. An experimental batch of 1000 shirts made of the cloth containing 20% chemically bound carboxide was tested in various parts of the USSR. The shirts gave 100% protection against gnats after 5 washes, 80% protection against crawling ixodid ticks after 2 washes, and 70% protection after 3 washes. Toxicological studies carried out on 110 individuals showed the safety of wearing these shirts. The shirts should be worn locally in areas with a high population density of blood-sucking arthropods when long-term protection is necessary.
