Flame retardant finishing composite fabric information for wool fabrics

Wool has a high moisture regain rate and ammonia content, and is naturally flame retardant. However, when the requirements are higher, flame retardant finishing is required. The earliest flame-retardant finishing agent for wool was the borax and boric acid solution impregnation method. The product was used for decorative cloth on aircraft, but it was not resistant to washing. Finally, THPC is used to fix the flame retardant on the fiber. The washability is good, but the process is complicated, the hand feels rough, and the style of wool fabric is lost. At present, flame retardant finishing of wool fabrics generally uses metal complex flame retardant finishing, which has good flame retardant effect and does not affect the fabric feel. 1. Flame retardant: Composite WFR-866 series flame retardant developed by Tianjin Institute of Synthetic Materials. One is WFR-866F (with fluorine complex as the main component), and the other is WFR-866B (with bromine-containing hydroxyl group as the main component). 2. Purpose: The pure wool flame-retardant fabrics thus processed are mainly used for carpets, curtains, wall coverings in aircraft cabins, high-end hotels, and military uniforms for school officers and above. 3． Finishing method: Flame-retardant finishing of wool fabrics is performed directly in the machine after the wool fabric is dyed and cooled down, without leaving the machine, to simplify the operation and achieve better results.
