<p>The present invention concerns a method of preparing a hybrid fiber including polyamide and polyester. Particularly, the method of preparing a hybrid fiber comprises, forming a blend by melting a) 4.99 to 95% by weight of a thermoplastic polyamide resin, b) 4.99 to 95% by weight of a thermoplastic polyester resin, and c) 0.01 to 10% by weight of an epoxy resin at 250 to 300° C., and blend spinning and elongating 10 to 90% by weight of the blend with 90 to 10% by weight of a polyester resin. The hybrid fiber shows highly improved compatibility of the polyamide resin and the thermoplastic polyester resin, and shows excellent strength and elongation.</p> |
