Was ist flammhemmender Vliesstoff?-
Der Hauptbestandteil von flammhemmendem Polyester-Vliesstoff ist Polyester, und Viskosefaser ist eine chemische Faser, die ein Polymerisationsprodukt von Terephthalsäure oder Diethylterephthalat und Ethylenglykol ist. Die Eigenschaften sind wie folgt: hohe Festigkeit, gute Elastizität, gute Wärmebeständigkeit, glatte Oberfläche, gute Verschleißfestigkeit, gute Lichtbeständigkeit, Korrosionsbeständigkeit und schlechte Färbbarkeit. Sein Flammschutzmechanismus besteht hauptsächlich darin, Flammschutzmittel, Flammschutzmittel, eine Art Materialzusatzstoff, der im Allgemeinen in Polyesterkunststoffen, Textilien usw. verwendet wird, zu Polyester hinzuzufügen, um Flammschutzmittel zu erreichen, indem der Zündpunkt des Materials erhöht oder behindert wird die Verbrennung des Materials. Ziel ist es, die Brandsicherheit des Materials zu verbessern.
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.
Zu den Teststandards gehören die amerikanischen CFR1633-, britischen BS5852- und amerikanischen TB117-Standards.
Produktbeschreibung

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 .
