conjugated spinning a filament comprising 75 wt.% polyester and 25 wt.% polyester to obtain a dissolution type ultrafine yarn, false twisting it and air bridging a false untwisting filament high shrinkage yarn having a 30-40 % nonaqueous shrinkage ratio, which is manufactured by polymerization of 10 wt.% a neopentyl glycol component and said composite yarn, and then using the composite finished yarn as a filling yarn. The produced fabric is treated by liquid melting-out method, thereby having a loss ratio of quality of 20-25 %, the degree of yarn division of 100 % and the tearing strength of dying buffing paper of 1,200-1,400 kg/cm2.
