Influence of non-woven fabric flame retardant

Polyester cotton has the reasons are as follows: (flame retardant effect of method A) Conventional polyester cotton limit oxygen index of 20 - 22 ( Content of 21% oxygen concentration in the air) , is a kind of combustible fibers, burn easily lit but slower. ( 2) If the modification polyester slice degeneration with flame retardant effect. Most long-acting type flame retardant fibers using modified polyester slice of the flame retardant polyester cotton production, the main modification agent for phosphorus series compounds, use of phosphorus in high heat and oxygen in the air, reduce the oxygen content of the characteristics of good flame retardant effect. ( 3) Another make with flame retardant polyester cotton to methods for the surface treatment method, this product is that treatment will reduce the effectiveness of flame retardant after many processing. ( 4) Polyester cotton have the characteristics of high heat shrink when fiber meet flame from not easily ignited flame due to shrinkage, appropriate flame retardant effect. ( 5) Polyester cotton have met high molten drops down, light polyester cotton produce after molten drops dripping phenomenon can also take part. Heat and flame, appropriate flame retardant effect. ( 6) But if on fiber with easy fuel oil or use can make polyester cotton stereotypes of silicone oil, will reduce the effectiveness of flame retardant polyester cotton. Especially polyester cotton containing SILICONE oil meet flame, fiber not contracting and burning. ( 7) Way to increase the flame retardant polyester cotton, in addition to using flame retardant modified polyester cotton, polyester slice production of fiber surface using phosphate higher oil reprocessing also can increase the effect of flame retardant fiber. Because encounter heat release of phosphate phosphorus molecules and oxygen molecules in the air at the same time reduce the oxygen content in the air, and increase the flame retardant properties.
