Fire-Resistant Viscose Rayon Fiber Materials

Abstract

The possibility of directly controlling the structure and properties of viscose rayon fiber materials is considered here in the modification with flame retardants and fire retardant systems. The dependence is shown of the degree of crystallinity, the physicomechanical properties, and thermolysis and combustion indicators of the materials on their textile structure, the composition of the modifying bath, and modification conditions. Initiating effect of flame retardants on dehydration processes and structure formation of fibrous materials is proven, evidenced by an increase in the yield of water, carbonized structures, and the oxygen index.
