LATENT DEEP-DYEABLE MIXED FIBER ENTANGLED YARN, CORE-SHEATH TYPE DEEP-DYEABLE MIXED FIBER ENTANGLED YARN, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a deep-dyeable mixed fiber entangled yarn excellent in any characteristics of worsted drape, slimy feeling, and deep-dyeability when turned into a woven or knitted fabric, and a method of manufacturing the same, and a latent deep-dyeable mixed fiber entangled yarn for obtaining the entangled yarn, and a method of manufacturing the same.;SOLUTION: The core-sheath type deep-dyeable mixed fiber entangled yarn comprises: a deep-dyeable polyester filament yarn a as a sheath yarn; and a heat-shrinkable yarn b as a core yarn where a mass ratio (yarn a)/(yarn b) of the deep-dyeable polyester filament yarn a to the heat-shrinkable yarn b is 60/40-85/15, the deep-dyeable polyester filament yarn has a fine pore on a single fiber surface having a size in a fiber direction of not greater than 0.9 μm, the number of the fine pores is not less than 10 in a 5 μm×5 μm size region on the single fiber surface, the area ratio of the fine pore is 10-50% in a 5 μm×5 μm size region on the single fiber surface, and the depth of the fine pore is 100-400 nm.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
