The two categories of fiber flame retardant properties

Although the specific fiber blending ratio according to the the flame retardant indicators, price positioning to determine, but the principle is: the good essence of the first class to use flame-retardant properties with the firefighter boot effect of fiber to provide basic flame retardant properties and complete performance of the film after combustion, the fiber from the domestic inter-aramid, the domestic Polyarylsulphonamide, the varieties of domestic polyarylene oxadiazole the fiber (PowerLeader Lun), selection, Pao-lun better dyeing performance, the higher the decomposition temperature, and the price is relatively cheap.
The second type fibers should be used to reduce the cost and improve the comfort of the fabric, the most typical is made flame-retardant viscose fibers, relatively cheap. But the retardant viscose strength is not high, if users need high strength fabric can add some of the strength of the flame-retardant polyvinyl alcohol, strength up 7.5cN/dtex, can alleviate the problem of low intensity of flame retardant viscose.
For wool, can be used a ratio of 20% to 30% of the fibers can still maintain a good flame retardant properties. The experiments show that 25% of the time without fire fighting equipment finishing of ordinary wool fabrics continued burning and smoldering time can also keep similar system are 0 seconds. The joint use of these fibers were different flame retardant mechanism can generate synergies in the different flame retardant mechanism to achieve good flame-retardant effect. And due to the second type of fiber than the first fiber is much cheaper, the cost performance of the final product will be very good.
