PURPOSE:To obtain the subject textured yarn suitable for high grade woven fabric of worsted type used for a field of men's overcoat in autumn and winter, having excellent soft touch, resilience and repulsive properties, showing no littering luster by texturing with filament groups having different size, etc., in core part and sheath part. CONSTITUTION:A polyester containing preferably >=80mol% ethylene terephthalate is made to (A) large size filament group having size of 6.5-11 denier and cross sections of 5-12 leaves. On the other hand, (B) a small size filament group having a size of 0.7-2 denier and cross sections of 4-8 leaves is spun. Then the component A as core part and the component B as sheath part are altogether textured in false twisting to afford the aimed textured yarn having a size ratio of the component B to the component A of 0.65-1.5 and 3-15% fiber length difference between filament groups. |
