Abstract

The paper presents the results of the research of influence of heat flow on the properties of flame-retardant fabrics of working clothes. It has been established that the developed modified Aflammite KWB fabric art. 3137OZT, is not inferior to domestic (cloth item 11475OP) and foreign (cloth BANOX 440) analogues in resistance to heat flow. The fabrics withstands thermal flux density up to 40 kW/cm2 during 1800 sec without significant loss of properties. Increasing the heat flux density above 40 kW/cm2 leads to a significant decrease in the breaking load and breaking elongation, loss of elasticity of the fabrics and increased bending stiffness.
