PURPOSE:To impart an excellent feather-like feeling without damage to a span-like feeling by drawing and arranging plural unstretched multi-filament yarns having mutually different elongation and dyeability, carrying out simultaneous stretching and false twisting in specified conditions and then carrying out fluid confounding treatment. CONSTITUTION:An unstretched multi-filament yarn (A) dyeable with ionic dyes and another unstretched multi-filament yarn (B) difficult to be dyed with the ionic dyes are subjected to simultaneous stretching and false twisting at >=60% elongation, 80-250%, preferably 100-230% difference of elongations and >=1.2 times, preferably 1.3-2.0 times draw ratio and formed into a yarn having a two-layer structure and 13-25%, preferably 15-20% difference of yarn lengths between the sheath and core parts. To the resultant yarn having the two-layer structure, conforming of >=50/m conforming ratio is imparted using a fluid conforming nozzle 9 having an impellent force in the direction of yarn traveling, thus obtaining the objective textured yarn alternately having confounding.focusing parts [part of fiber yarn (A) and (B) are mixed and mingled with each other at the boundary part] containing twist yarn-like interwinding parts and opened parts in the longitudinal direction. |
