Dab tsi yog nplaim retardant uas tsis yog - woven npuag?
Cov khoom tseem ceeb ntawm cov nplaim hluav taws kub nyhiab tsis yog -cov ntaub yog polyester, thiab viscose fiber yog cov tshuaj fiber ntau, uas yog cov khoom siv polymerization ntawm terephthalic acid lossis diethyl terephthalate thiab ethylene glycol. Cov yam ntxwv yog raws li nram no: siab zog, zoo elasticity, zoo tshav kub kuj, du nto, zoo hnav tsis kam, zoo lub teeb kuj, corrosion kuj, thiab tsis zoo dyeability. Nws cov nplaim retardant mechanism yog tsuas yog ntxiv nplaim retardant, nplaim retardant, uas yog ib yam ntawm cov khoom additive, feem ntau yog siv nyob rau hauv polyester plastics, textiles, thiab lwm yam., ntxiv rau polyester kom tiav nplaim retardant los ntawm nce lub ignition point ntawm cov khoom los yog hindering. combustion ntawm cov khoom. Lub hom phiaj yog txhawm rau txhim kho kev nyab xeeb hluav taws ntawm cov khoom siv.
There are many kinds of flame retardants, including halogen-based flame retardants, organic phosphorus-based and phosphorus-halogen-based flame retardants, intumescent flame retardants and inorganic flame retardants. At present, brominated flame retardants are the most used halogen flame retardants.
Polypropylene fiber is a synthetic fiber made of propylene as raw material. It features: high strength, good wet and dry strength, abrasion resistance and corrosion resistance. Viscose fiber belongs to regenerated cellulose fiber, which has the characteristics of good hygroscopicity, lower breaking strength than cotton, environmental protection, non-toxic, and higher price than other fibers.
Flame retardant non-woven fabrics can be divided into flame retardant needle cotton and flame retardant hot air cotton according to the process. The flame retardant needle cotton is formed by entanglement of fibers after being punctured by a needle punching machine; the 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, and the commonality is flame retardant, light, warm, durable and environmentally friendly.
Cov qauv xeem suav nrog American CFR1633, British BS5852 thiab American TB117 cov qauv.

Cov khoom siv hluav taws xob hluav taws xob hluav taws xob muaj cov nplaim hluav taws kub thiab tiv thaiv- cov dej ntws tawm, thiab tuaj yeem tsim cov nplaim hluav taws kub hnyiab tau zoo.
① US CFR1633 test content: During the 30-minute test period, the maximum caloric heat release peak of the mattress or mattress set must not exceed 200 kilowatts (KW), and the total heat release must be less than 15 megawatts (KW) during the first 10 minutes of release Joules (MJ), 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, as well as the damage length, basically use a lighter to burn vertically on the textile surface for 20 seconds, and within 12 seconds after leaving the flame, the flame will automatically go out.
③American 117 test content: cigarette test, the overheated part does not exceed 80 percent , the average burning length does not exceed 3 inches, the maximum burning length does not exceed 4 inches, the average burning time does not exceed 4 seconds, the longest burning time does not exceed 8 seconds, open flame The loss of combustion quality does not exceed 4 percent .
