Abstract

PURPOSE:To obtain a specialty bulky polyester yarn having silky feeling and bulkiness, etc., and giving a cloth having tightness and body, by using polymers having different melting points and imparting the yarn groups of the different polymers with single filament denier difference and shrinkability difference by non-uniform heat-treatment. CONSTITUTION:The low-melting polymer used in the present yarn is a polyester copolymerized with >=5mol.% of a 3rd component and the high-melting polymer is composed mainly of polyethylene terephthalate. The melting point difference between both polymers is 10-50 deg.C. The low-melting polymer is extruded and spun through nozzles 7 at the center of a spinneret and the high-melting polymer is extruded and spun through the circumferential nozzles 8 of the spinneret and the filaments are blended. The drawn yarn is subjected to non-uniform heat-treatment on a heater heated at a temperature Talpha [lower than the melting point ( deg.C) of low-melting filament minus 20 deg.C and higher than the secondary transition point ( deg.C) of the low-melting filament plus 90 deg.C] and then to heat- treatment with another heat-treating member at a temperature Tbeta (lower than Talpha and higher than Talpha-30 deg.C) under a condition essentially free from elongation.
