Title:

ANTISTATIC CORE-SHEATH TYPE ULTRAFINE-DENIER FALSE-TWISTED POLYESTER YARN, PROCESS FOR PRODUCTION THEREOF, AND ANTISTATIC WATER-REPELLENT FABRICS COMPRISING THE YARN

Document Type and Number:

WIPO Patent Application WO/2008/053977

Kind Code:

A1

Abstract:

Since the false-twisted polyester yarn of the invention contains an antistatic component in a state enveloped in a sheath, the antistatic component is little deformed by false twisting. Therefore, the yarn little fluffs in false twisting and can give a polyester fabric which is improved in antistatic properties while retaining the soft hand, hot insulation, and water- and moisture-absorbing properties inherent in conventional ultrafine-denier false-twisted polyester yarn. The antistatic component of the yarn of the invention is excellent in heat resistance as compared with conventional polyether amide antistatic agents, so that the fabric is excellent in washing durability in a state dyed by the high-pressure method and thus useful as antistatic fabric for student's wear, uniform, dust protective wear, and so on.
