1. Flame-retardant non-woven fabrics can be divided into three categories according to their materials:


Polyester flame-retardant non-woven fabric, polypropylene flame-retardant non-woven fabric and viscose flame-retardant non-woven fabric. This is mainly divided according to their main components.

The main component of polyester flame-retardant non-woven fabrics is polyester, which 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, corrosion resistance, and poor dyeability.


Polypropylene fiber is a synthetic fiber made from propylene.


Viscose fiber belongs to regenerated cellulose fiber.


It has good moisture absorption, lower breaking strength than cotton, environmental protection and non-toxic.

 

Flame-retardant non-woven fabrics can be divided into flame-retardant needle cotton and flame-retardant hot-air cotton according tothe process.


Flame-retardant needle cotton is made of tangled fibers after being punctured by a needle punch.


Flame-retardant hot-air cotton is mainly formed by hot air passing through the furnace after laying the net.


Both products have their own characteristics. The common features are flame retardant, light, warm, durable, and environmentally friendly.


The testing standards include American 16CFR1633, British BS5852 and American TB117, CA133 standards.


2. Introduction of flame-retardant cotton products


Flame-retardant cotton products have flame-retardant and anti-melt dripping effects, and can effectively form a flame-retardant firewall.


The test content of 16CFR1633 in the United States: During the 30-minute test time, the peak heat release of the mattress or mattress set must not exceed 200 kilowatts (KW), and the total heat release must be less than the first 10 minutes of release 15 megajoules (MJ),


Material:Anfang flame retardant fiber (viscose fiber), 4080 fiber (low melting point fiber)


Uses:Mainly used in mattresses, cushions, sofas, seats and home textile products.


②British BS5852 main test standard: mainly test cigarette butts and use acetylene flame to simulate matches for testing, as well as the length of damage. Basically, use a lighter to burn vertically on the textile surface for 20 seconds. The flame will automatically go out within 12 seconds after leaving the flame.


③American 117 test content: cigarette test, the overfire part does not exceed 80%, the average burn length does not exceed 3 inches, the larger burn length does not exceed 4 inches, the average burn time does not exceed 4 seconds, and the longer burn time does not exceed 8 seconds. The quality loss of open flame combustion does not exceed 4%.


Role:fire prevention


Uses: soft furniture, mattresses, toys, home textile products


Material:polyester fiber
