Abstract:
1. A method for preparing a non-dripping flame retarding fiber, the method comprising the steps of: admixing a flame retardant in an amount of about 1.0 wt % to about 15.0 wt %, a crosslinking agent in an amount of about 0.1 wt % to about 1.5 wt %, a nylon polymer in an amount of about 76.5 wt % to about 99.5 wt %, and a dispersing agent in an amount of about 0.1 wt % to about 5.0 wt % to form a admixture; adding a crosslinking initiator in an amount of about 0.01 wt % to about 2.0 wt % into the admixture to form a composition for compounding; compounding the composition for about 1-20 minutes at a compounding temperature of about 220-270° C. to obtain a compounded product; pelletizing the compounded product to obtain a non-dripping flame retarding masterbatch; and spinning the non-dripping flame retarding masterbatch to obtain the non-dripping flame retarding fiber having an elongation of at least 45%.
