Qu'est-ce qu'un tissu non-ignifuge ?
Le composant principal du tissu non tissé ignifuge en polyester-est le polyester, et la fibre de viscose est une fibre chimique, qui est un produit de polymérisation de l'acide téréphtalique ou du téréphtalate de diéthyle et de l'éthylène glycol. Les caractéristiques sont les suivantes : haute résistance, bonne élasticité, bonne résistance à la chaleur, surface lisse, bonne résistance à l'usure, bonne résistance à la lumière, résistance à la corrosion et mauvaise aptitude à la teinture. Son mécanisme ignifuge consiste principalement à ajouter un retardateur de flamme, un retardateur de flamme, qui est une sorte d'additif de matériau, généralement utilisé dans les plastiques polyester, les textiles, etc., ajouté au polyester pour obtenir un retardateur de flamme en augmentant le point d'allumage du matériau ou en entravant la combustion du matériau. L'objectif est d'améliorer la sécurité incendie du matériau.
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.
Les normes de test incluent les normes américaines CFR1633, britanniques BS5852 et américaines TB117.
Description du produit
Les produits en coton ignifuge ont des effets ignifuges et anti-gouttelettes, et peuvent former efficacement un pare-feu ignifuge.
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 .
