Title:
POLYESTER CONJUGATE FILAMENT THICK-FINE YARN FABRIC AND METHOD FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2003/093547
Kind Code:
A1
Abstract:
A method for producing a polyester conjugate filament thick-fine yarn fabric, which comprises melting two types of polyester having different intrinsic viscosities and spinning the resulting melts into a conjugate multifilament yarn, winding the multifilament yarn up at a rate of 1000 to 4500 m/min, stretching, while unwinding, the yarn non-uniformly at a stretch ratio lower than the natural stretch ratio of the yarn, so as to form a thick-fine yarn having a thickness ratio of 1.05 or more, preparing a fabric using the resultant yarns, subjecting the fabric to an alkali weight reduction treatment at a weight reduction ratio of 3 to 30 mass %, to thereby form, on the surface of a single filament, a number of cracks extending to the direction crossing with the fiber axis. The polyester conjugate filament thick-fine yarn fabric exhibits a feeling and also an appearance like a worsted fabric in combination with good stretching property.
