Patent ID: 8372902

Claim:
A non-dripping flame retarding fiber, comprising: a crosslinked nylon polymer, comprising about 76.5 wt % to about 99.5 wt % of a nylon polymer based on the total weight of the non-dripping flame retarding fiber, and about 0.1 wt % to about 1.5 wt % of a crosslinking agent based on the total weight of the non-dripping flame retarding fiber, wherein the crosslinking agent is a diallyl compound or a triallyl compound; and a fire retardant dispersed within the crosslinked nylon polymer, wherein the fire retardant is present in the non-dripping flame retarding fiber in an amount of about 0.1 wt % to about 15 wt %, wherein the crosslinked nylon polymer having the fire retardant dispersed therein is formed by compounding, and the non-dripping flame retarding fiber is drawn from the crosslinked nylon polymer having the fire retardant dispersed therein and has an elongation of at least 45%.
