METHOD FOR MAKING ULTRAFINE MIXING YARN WITH EXCELLENT TACTILE SENSATION

摘要

The mixed yarn is prepared by spinning normal poylester and polyester as core part at 2,000-4,000m/min and 285-295deg.C, and reformed copolymer as initial part comprising 3-5wt% of sodium sulfodiphenyl isophthalate as extraction compn. and 0.5-2wt% of organic polymer added by ethylene oxide or propylene oxide to isophthalic acid and bisphenol A at 2,000-4,000m/min and 250-270deg.C to have the ratio of core and initial part of 80:20 and 16 surface distribution type; mixing spun partially drawn yarn and partially drawn yarn of normal polyester under 2-15g tension, and twisting to have a interlacing no. of 70-100/m.
