PURPOSE:To obtain the title combined filament yarn having an excellent swelling, dry touch, drape characteristics by feeding combined filament yarn comprising >=a fixed amount of polyesterbased fiber containing specific fine particles in the fiber to a device so as to form specific surface. CONSTITUTION:The objective specific combined filament yarn, combined filament yarn comprising (A) >=30wt.% polyester filament containing >=4wt.% fine particles having <=1mum average particle diameter, <=2.0 refractive index and >=2.5 true specific gravity and (B) PET filament, wherein part of sheath yarn has three or more loops/25mm having 0.5-2.5 coefficient of protrusion (height of protrusion/width of protrusion) and the height of the protrusion >=1/3 diameter of the yarn, one or more slack parts/25mm based on difference in yarn length having height of >= diameter of yarn and <= three times diameter and width of >= twice the height and >=40/m interlaced parts. |
