摘要： A process for forming and modifying a self-crimping polyester yarn comprising a plurality of polyester filaments having thick and thin regions along their lengths which are out of phase from filament to filament. The plurality of filaments are produced by first forming a plurality of combined streams of molten melt spun polyester by combining at least first and second extruded molten streams of fiber forming polyester travelling at different extrusion speeds to thereby from thick and thin regions in the combined streams out of phase from other combined streams. The combined streams are then quenched and thereby transformed into solid filaments in a solidification zone provided with a gaseous atmosphere at a temperature below the glass transition temperature of the polyester. The resulting filaments are then passed in the direction of their lengths through a conditioning zone, which zone is provided with a gaseous atmosphere at a temperature sufficient to decrease the percentage yarn shrinkage of the resulting filaments and to produce polyester filaments which exhibit a per cent yarn shrinkage in the range of from 10 to 45 per cent. The resulting filaments are withdrawn from the conditioning zone at a substantially constant wind-up speed in the range 2012 to 4023 m/min. The yarn thus obtained still exhibits a useful degree of crimp as well as properties similar to those observed in yarns spun at much higher wind-up speeds.

摘要翻译：一种用于形成和改性自卷曲聚酯纱线的方法，其包括多个聚酯长丝，其长度从长丝到长丝不同而具有厚而薄的区域。多个长丝通过首先通过将至少第一和第二挤出的熔融流动的纤维形成聚酯以不同的挤出速度组合而形成熔融熔融纺丝聚酯的多个组合流，从而从组合流中的厚而薄的区域从其他组合流的相位。然后将合并的物流淬灭，从而在低于聚酯的玻璃化转变温度的温度下在具有气体气氛的固化区中转变为固体长丝。然后将所得长丝沿其长度方向通过调节区，该区域在足以降低所得长丝的纱线收缩率的百分比的温度下提供气态气氛，并产生显示出百分比的纱线的聚酯长丝收缩率在10％至45％之间。所得的细丝以约为2023m / min的范围内的基本恒定的卷取速度从调节区域中取出。由此获得的纱线仍然表现出有用的卷曲程度以及类似于在高得多的卷取速度下旋转的纱线中观察到的那些。
