PROBLEM TO BE SOLVED: To obtain a special false-twist textured yarn with excellent harshness feel by subjecting specific twistless thermoplastic synthetic multifilament yarn to false-twist texturing process under specified conditions so as to enable the knit fabrics made therefrom to be provided with surface unevennesses of natural irregularity feeling and stretch characteristics. ;SOLUTION: This false-twist textured yarn is obtained by performing a false-twist texturing process for twistless thermoplastic synthetic multifilament yarn ≤20 T/m in the number of twists as feed yarn under such conditions as to meet the relationships I to III [LT is the number of false twists in forming twistless low-crimped portions 1 (T/m); HT is the number of twists in forming twistless high-crimped portions 2; D is the fineness of the final textured yarn (dTex); α is the rate of increasing/decreasing the number of false twists (T/s); V is the rate of false-twist texturing (m/min)]. This false-twist textured yarn thus obtained has the number of twists in the respective real twisted portions in the 1st and 2nd mixed structural parts 3, 4 of 100-2,000 (T/m) and meets the following condition: 0.03≤(the sum of the lengths of the respective real twisted portions in 1st and 2nd mixed structural parts 3, 4/the sum of the respective lengths of the twistless low-crimped portion 1 and twistless high-crimped portion 2)≤0.3.;COPYRIGHT: (C)2000,JPO
