How Are Nonwoven Fabrics Flame Retardant?

Non Woven Fabric is made by needle process, it can be used in different industries, such as sound insulation, heat insulation, electric heater, mask, clothing, medical and filling materials, etc. How does Nonwoven Fabric achieve flame retardancy?

There are two main ways to realize the flame retardant function of non woven fabrics:
1. Through polymer polymerization, blending, copolymerization, composite spinning and graft modification, etc., the flame retardant with flame retardant function is added to the fiber to prepare the fiber flame retardant.
2. Apply the flame retardant on the surface of the Filter Fabric or penetrate into the fabric through the post - finishing method.

The flame retardant effect of Non Woven Fabric Roll is achieved by adding flame retardants. For flame retardants used on nonwovens, they must meet the following conditions:
1. Low toxicity and long - lasting, which can make the product meet the requirements of flame retardant standards;
2. Good thermal stability, less smoke, which can meet the requirements of non woven fabric;
3. Do not significantly reduce the original performance of non woven fabric;
4. The price is very cheap, which helps to reduce the cost.
The use of non woven fabrics provides more choices for people ' s lives. It can use small pores to purify the air and block bacteria and viruses.
