PURPOSE:To obtain the subject textured yarn suitable for woven fabric of worsted type as spunlike woven and knit fabric for suits, having excellent feeling and appearance, by texturing with two filaments of different dyeabilities for ionic dye in core part and sheath part. CONSTITUTION:(A) A polyester of badly dyeable for ionic dye, such as polyethylene terephthalate is made to a large size filament having a size of 6.5-11 denier and a cross section of 5-12 leaves. On the other hand, (B) a polyester containing a group dyeable for ionic dye (e.g., sulfonate metal base) is made to a small size filament having a size of 0.8-2.2 denier and a cross section of 4-8 leaves. Then the component A is used to core part and the component B to sheath part to obtain the aimed textured yarn comprising a size ratio of B to A of 0.7-1.4 and 4-20% fiber length difference between filaments. |
