Abstract

PURPOSE: The titled fiber with specific values of initial tensile resistance, crystal size in (100) surface, dry heat shrinkage, crimp number, precentage crimp, the ratio of percentage crimp to crimp number, the lowering rate of percentage crimp by loading weight, filament denier and cross section modification ratio, thus showing three-dimensional crimps.
CONSTITUTION: Polyethylene terephthalate is melt-spun through a spinneret with nozzle of modified cross section with l slit width, the extruded yarns are asymmetrically cooled right under the spinneret by blowing the cooling air only from one side, and heat treated under relax to produce fiber of modified cross section that has high than 32g/d initial tensile resistance, larger than 28Å crystal size ACR in (100) surface, less than 5% dry heat shrinkage SHD at 160°C, 4 or more per inch crimp number CN, more than 5% percentage crimp Ci, 1 or more Ci/CN ratio, less than 75% the lowering rate of ci when the weight of 1g/d is loaded CiR, 4W20 filament denier D, more than 10% hollow percentage at the fiber cross section and more than 4,600/C1/2 modification ratio at cross section.
