For flame-retardant non-woven fabrics to be flame-retardant, we all need to cut it off. It is mainly a combustion cycle system composed of heat sources, combustibles and oxygen. What are the main methods for flame retardant textiles to achieve flame retardancy?

1. Increase the temperature at which the fabric thermally cracks.

2. Remove the heat source.

3. Promote char formation and reduce the generation of volatile gases.

4. Isolate oxygen or dilute the oxygen concentration.

5. Increase the temperature required for combustible gas combustion.
