Development of a method for fire-resistant finishing of non-woven material using a phosphorus-containing composition

Abstract

The aim of the study is to obtain a non-woven material with flame retardant properties. The conditions of the process of fire-retardant finishing were as follows: an aqueous solution of preparations of various concentrations was applied by spraying onto the surface of the material, then drying was carried out and heat treatment on a thermal press. According to GOST R 50810-95, non-woven material made from flax and wool fibers, treated with a composition based on an aqueous solution of sodium phosphate and guanidine hydrochloride, is classified as a flame-retardant material. Also, tests for toxic and skin-irritating effects of non-woven material treated with the proposed composition showed its safety for human health.
