PCT No. PCT/JP88/01125 Sec. 371 Date Jun. 15, 1989 Sec. 102(e) Date Jun. 15, 1989 PCT Filed Nov. 7, 1988 PCT Pub. No. WO89/04388 PCT Pub. Date May 18, 1989.A flat multifilament yarn having a very soft unique touch is obtained by arranging two or more types of multifilament yarns having different drawings properties in parallel, and applying a false twisting procedure which includes a twist applying and twist releasing operations to the paralleled multifilament yarn at a temperature of 120 DEG C. or less, and subjecting the resultant false twisted composite yarn to a heat treatment at a temperature of 130 DEG C. or more in a subsequent procedure, the resultant high elongation multifilaments derived from the high drawability multifilaments in the multifilament yarn having a crystallinity (density method) of 10% to 30%, a non-crystalline portion orientation of 0.035 to 0.10, a non-crystalline portion density of 1.31 to 1.36 g/cm3, and a Young's modulus of 200 to 700 kg/mm2.
