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

摘要

The polyester false-twist textured yarn of the present invention has a sheath part encapsulating an antistatic component, and is not susceptive to deformation of the false-twist, therefore a little fluff in false-twist texturing occurs. Thus, a polyester textile that is excellent also in antistatic performance, while maintaining such performances as soft feeling, warmth-retaining property, water-absorbing property, hygroscopic property that belong to an ultrafine polyester false-twist textured yarn. Further, since it is excellent in heat-resisting properties as compared with conventional polyetheramide-based antistatic agent, the yarn is excellent in wash durability when it is high-pressure dyed and can be suitably used for a textile for use in such applications as school uniform, uniform and dustproof wear for which static charge should be prevented.
