随着社会的发展和进步,人们对于安全防护的要求越来越高,产品不断更新换代,使用永久阻燃新材料的劳动防护用品必然会逐渐替代以阻燃剂整理的、以棉为主的劳动防护用品。目前,国际上先进的永久阻燃环保材料芳纶阻燃纤维越来越受人们欢迎。阻燃纤维阻燃纤维一般可分为两类。一类是将具有阻燃功能的阻燃剂通过聚合物共聚、共混、复合纺丝、接枝法等方式加入到纤维的内部或表面,使纤维具有阻燃性能。例如阻
With the development and progress of the society, people demand more and more for the protection of the security and the products are constantly updated. The labor protective articles that use the permanent fire-retardant new materials will inevitably gradually substitute the fire-retardant finishing materials and the cotton-based ones Labor protection products. At present, internationally advanced flame retardant aramid flame retardant fiber is more and more popular. Flame retardant fiber flame retardant fiber can be divided into two categories. One is to add the flame retardant with flame retardancy to the interior or the surface of the fiber through polymer copolymerization, blending, composite spinning, grafting, etc., so that the fiber has flame retardant properties. For example, resistance
