ABSTRACT:
A false twisting yarn composed of monofilaments containing a polyester component of which main component is polytrimethylene terephthalate, wherein the false twisting yarn is a false twisting yarn which satisfies all of the requirements of (1) a shrinkage ratio by wet heat treatment at 98° C. for 20 minutes is 5% or less, (2) a ratio (TS/WS) of elastic stretch ratio after wet heat treatment at 90° C. for 20 minutes (WS) and elastic stretch ratio after dry heat treatment at 90° C. for 15 minutes (TS) is, 0<TS/WS≦1, and (3) a tensile strength is 2.0 cN/dtex or more. By using the false twisting yarn, it is possible to produce a pile cloth having a soft touch and a low shrinkage.
