(57) [Summary] [Object] To provide a highly flame-retardant polyamide fiber containing no halogen, antimony, or phosphorus, a method for producing the same, and a highly flame-retardant carpet using the same. (A) A polyamide is mixed with an additive having a vulcanizable mixture of silicone and a catalyst in a thermoplastic resin matrix in an amount of about 0.05 to about 50% by weight based on the total amount of the fiber composition, b) A process for producing polyamide carpet fibers with improved flame retardancy, which comprises melt mixing the above polyamide and the above additives at a temperature of about 250 to 300 ° C. and (c) fiber melt spinning. |
