The meaning of flame retardant fabric is that when the fabric encounters an open flame, it will automatically extinguish in a short time, rather than not burning. It can reduce the flammability of fabrics in flames, slow down the spread, and prevent large-area burning.
The basic principle of flame retardant fiber is to reduce the generation of flammable gases during thermal decomposition and to hinder the basic reactions during gas phase combustion. Secondly, absorbing heat in the combustion area, diluting and isolating the air also plays a certain role in preventing combustion.
Principle 1 of flame-retardant fabrics: heat absorption and flame retardancy. Through endothermic dehydration, phase change, decomposition or other endothermic reactions of the flame retardant solvent, the temperature of the polymer surface and combustion zone is reduced, thereby slowing down the thermal decomposition rate of the polymer. Water vapor can dilute and cool flammable gases to achieve flame retardant purposes.
Principle 2: Condensed phase flame retardant. Condensed phase flame retardant mainly uses flame retardants to affect the decomposition process of polymers and reduce the generation of flammable gases. This method is particularly effective for cellulosic materials.
Principle 3: Some substances (such as boron yarn, boric acid, etc.) melt when heated and form a glass-like film on the surface of the fiber, which can hinder the supply of oxygen; or like phosphide, it mainly The solid phase acts to promote carbonization and prevent the release of flammable gases.
