What are the classifications and principles of flame-retardant non-woven fabrics?

Flame-retardant non-woven fabrics are divided into three types according to their main components: polyester flame-retardant non-woven fabrics, polypropylene flame-retardant non-woven fabrics and viscose flame-retardant non-woven fabrics. What are the classifications of flame-retardant non-woven fabrics?

1. The main component of polyester flame-retardant non-woven fabric is polyester. Polyester fiber is a chemical fiber and is a polymerization product of terephthalic acid or diethyl terephthalate and ethylene glycol.
Features: high strength, good elasticity, good heat resistance, smooth surface, good wear resistance, good light resistance and corrosion resistance.

2. Polypropylene fiber is a synthetic fiber made from propylene.
Features: high strength, good wet and dry strength, wear resistance and corrosion resistance.

3. Viscose fiber belongs to regenerated cellulose fiber.
Features: It has good moisture absorption, lower breaking strength than cotton, environmental protection and non-toxic.

The flame-retardant principle of flame-retardant non-woven fabrics is mainly to add flame-retardant in the production to achieve the purpose of flame-retarding and improve the fire safety of the material. In actual production, there are many kinds of products, and each has its own advantages.
