Abstract

This article presents the results of studies on the flammability and fire resistance of some natural fibers and textiles. The study of the flammability and fire resistance of some natural fibers and textiles is important to protect them from fire. Natural fibers are two categories: cellulose (cotton, linen, jute, kenaf, etc.) and protein (silk, wool, leather, etc.). The chemical composition of cellulose and protein fibers is different. Therefore, the study of the flammability and fire resistance of natural fibers and textiles is important not only from the point of view of fire danger, but also for economic reasons. The mechanism of combustion of cellulose fibers was studied. In cellulose fibers, the main flammable element is carbon. The chemical composition of wool and silk is nitrogen. Nitrogen is not flammable and does not support combustion. Fire retardants prevent the release of gases by forming a barrier. This barrier also prevents oxygen from entering the combustion zone. Thus, heat is absorbed by chemicals and reduces the combustion surface. Treated materials with flame retardants emit less combustible gases. Processed wool is used in the manufacture of protective clothing, carpets and other goods in the national economy.
