PURPOSE:To obtain conjugate textured yarn suitable for spun-like woven and knit fabric comprising at least three species of polyester filament groups of different filament sizes each other, having specific filament size, size difference and fiber length difference between each group. CONSTITUTION:The subject yarn is constructed that filament size of filament group respectively constructing core part, inner part of sheath part and outer part of sheath part is respectively set as 6.5-11 de, 2.5-4.5 de and 0.7-2.0 de. Ratio of size of filament group composing sheath part to size of filament group (group A) composing core part is 0.75-2.0 and ratio of size of filament group composing outer part in sheath part to size of filament group (group B) composing inner part in sheath part is 0.5-2.0. Further, 3-13% fiber length difference L is between the group A and the group B, 4-15% fiber length difference M is between the group A and the group B and (length difference M)-(length difference L)>=1.0% and confounding is imparted on whole strand. |
