What are the basic principles of fire retardant cloth?

The meaning of flame-retardant fabrics is that when the fabric encounters an open flame, it will automatically extinguish within a short period of 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.
