PROBLEM TO BE SOLVED: To provide a bulky mixed textured yarn of a polyamide, providing a fabric having sufficient bulkiness and stretchability by being subjected to heat treatment. SOLUTION: The bulky mixed textured yarn of the polyamide has a core-sheath structure composed of a core yarn comprising a fiber A obtained by sticking two kinds of polyamides having difference in viscosity so as to form a side-by-side shape, and a sheath yarn comprising a polyamide fiber B. The difference of shrinkages of the fibers A and B in hot water is≥5%, and the textured yarn has 10-45% percentage crimp,≥70% modulus and≥10% recovery. COPYRIGHT: (C)2004,JPO&NCIPI
