Abstract

PURPOSE: Titled polyester fiber whose initial stretching resistance, dry-heat shrinkage, size of crystal and others are made to specified values, thus having high bulkiness performance originated from high three-dimensional crimping and high crimping fastness from mechanical and thermal points of view.
CONSTITUTION: A polyester containing ethylene terephthalate as the major recurring unit is made into fiber by a special direct spin-draw method, preferably at 4,000W6,000m/min taking-up speed, to produce three-dimensionally crimped fiber that has an intial stretching resistance of higher than 32g/d, crystl size of larger than 28Å at (100) face, a dry-heat shrinkage of less than 5%, a number of crimp A of more than 4/inch, a crimp percentage B of higher than 5% where B/A is higher than 1 and a reduction rate in crimp percentage on 1g/d loading of less than 75%, a filament denier of 4W20 and substantially no inflection point in the load-elongation curve on a filament tensile testing.
