Are flame retardant fabrics effective in fire protection? - Clothing Manufacturer

The flame retardancy of fabrics is often achieved through the principles of gas phase flame retardancy, condensed phase flame retardancy and interrupted heat exchange flame retardancy. It is a gas phase flame retardant that can freely exert the function of flame retardant fabrics by inhibiting the growth of the combustion reaction chain; it is a condensed phase flame retardant that plays a flame retardant role by delaying or preventing the thermal decomposition of polymers in the solid phase; it can absorb part of the heat generated by burning polymers. The flame retardancy caused by taking away the heat exchanger belongs to the type of flame retardancy that interrupts the heat exchange mechanism.

Polyester flame-retardant fabric has high fiber strength, excellent heat resistance and chemical stability. It is widely used in home textiles and various interior fabrics. However, it melts easily and has relatively Big fire hazard. Therefore, it is very important to study the flame retardant technology of polyester textiles and develop flame retardant polyester textiles.

The traditional intumescent flame retardant system is composed of acid source, carbon source and gas source. The acid source first releases inorganic acids with dehydrating effects such as phosphoric acid and pyrophosphoric acid, which react with polyols for esterification. The entire system melts during this process; the gas source produces non-combustible gas and water vapor, causing the melted system to foam and expand. ; The carbon source is further dehydrated and carbonized under the action of the dehydrating agent to generate organic matter and coke residues, causing the entire system to melt and expand to form a foamed carbon layer.
