Title:
EXPANSION FLAME RETARDANT SYSTEM FOR MATTRESS OR PILLOW INNER-SLEEVE FILLER FLAME RETARDATION AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/091976
Kind Code:
A1
Abstract:
Disclosed is an expansion flame retardant system for mattress or pillow inner-sleeve filler flame retardation and a method therefor. Yarns or cloth with cellulosic fibres or cellulosic fibres blended with chemical fibres as a raw material are processed and treated using an inorganic flame retardant containing nitrogen and phosphorus, so that the yarns or the cloth and the inorganic flame retardant containing nitrogen and the phosphorus constitute the expansion flame retardant system; by using a covering expansion function achieved when the inorganic flame retardant containing nitrogen and phosphorus is heated, the yarns or the cloth have a flame retardance; the yarns or the cloth are made into an inner sleeve of a mattress or a pillow, and the inner sleeve wraps a filler, so that in case of open fire on the mattress or the pillow, flames cannot pass through the inner sleeve to ignite the filler, and the flame retardation of the mattress or the pillow is realized, which passes the America 16CFR1633 mattress flame retarding standard test. The price of the flame retardant mattress inner sleeve treated by the method of the present invention is lowered by half in comparison with a mattress inner sleeve formed by weaving glass fibre flame retardant core-spun yarns. In addition, the former is degradable in the natural environment after being discarded, while the glass fibre contained in the latter cannot be naturally degraded, which may pollute the environment; besides, smoke resulting from the former is obviously less than that generated resulting from the latter in outbreak of fire.
