<p>A false twisting yam composed of monofilaments containing a polyester component of which main component is polytrimethylene terephthalate, wherein said false twisting yarn is a false twisting yam 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 yam of the present invention, it is possible to produce a pile cloth having a soft touch and a low shrinkage.</p> |
