Abstract
PURPOSE: In high-speed spinning of extremely fine polyamide yarns, the distance between the spinneret and the yarn collecting point is regulated in a specific range to produce title yarns having a crystal structure in which and γ-type α-type are adequately distributed, good flexibility, level dyeing properties and dyeing fastness.
CONSTITUTION: In the high-speed spinning of polycapramide at a taking-up speed exceeding 3,000 m/min to produce filaments of less than 1 denier, the distance, L in m, between the spinneret and the yarn collecting point is regulated in the range satisfying the equation [S is take-up speed in m/min, De is filament denier after take up in denier]. The resulting filaments have a specific crystal structure in which α-crystal form giving dyeing fastness and γ-crystal form giving soft feel because of its flexibility and good level-dyeing properties are adequately distributed with an optical birefringence (Δn) of over 0.045.
