PURPOSE:To obtain the subject textured yarn which is a bulking textured yarn, having loops with soft feeling and consisting of a polyamide-based multifilament yarn having a specific initial tensile strength value, residual elongation and shrinkage factor in boiling water and excellent in elastic recoverability. CONSTITUTION:The objective textured yarn, consisting of preferably a polyamide-based multifilament yarn prepared by spinning at a high speed of preferably >=3500m/min, obtained by subjecting the resultant multifilament yarn to fluid turbulent treatment and forming a bulking textured yarn with loops and having <=20g/d initial tensile strength value, >=35% residual elongation and <=8% shrinkage factor in boiling water and improved process passableness. Furthermore, the above-mentioned multifilament yarn is preferably a modified cross section yarn. |
