摘要： A polyamide (preferably nylon 66) partially oriented feed yarn contains a small amount of branching agent and has an elongation between 45 and 150%. The feed yarn can be textured by the friction twist process to yield a textured yarn having crimp development similar to yarn textured by the much more expensive pin twist method.
摘要翻译：聚酰胺（优选尼龙66）部分取向的进料纱含有少量的支化剂，并且具有45-150％的伸长率。进给纱线可以通过摩擦扭转过程进行纹理化，以产生具有卷曲显影的变形纱线，其类似于通过更昂贵的针捻法进行织纹的纱线。

摘要： A particular elastomeric polyurethane polymer is heated to about 225.degree.C. to ensure complete melting prior to extrusion side-by-side with a molten hard polymer. The polyurethane polymer is made from an aromatic diisocyanate, a high molecular weight (800-3000) diol and a low molecular weight (500 or less) diol, combined in specific ratio ranges.

摘要： Provided is 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 form 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 produce polyester filaments which exhibit a percent yarn shrinkage in the range of from about 10 to about 45 percent. The resulting filaments are withdrawn from the conditioning zone at a substantially constant wind-up speed.The yarn thus obtained still exhibits a useful degree of crimp as well as properties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：提供了一种形成和改性自卷曲聚酯纱线的方法，该自动卷曲聚酯纱线包括多个聚酯长丝，其具有沿着它们的长度的厚而薄的区域，其长度与长丝不同。通过首先通过组合以不同挤出速度行进的至少第一和第二挤出的成形聚酯的熔融流，形成熔融熔融纺丝聚酯的多个组合流，从而在组合的料流中形成厚而薄的区域来生产多根长丝的相位来自其他组合流。然后将合并的流淬灭，从而在低于聚酯的玻璃化转变温度的温度下在具有气态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，该区域在足以产生聚酯长丝的温度下提供气态气氛，该聚酯长丝在约10至约45％的范围内显示出百分比的纱线收缩率。所得细丝以大致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，以及与以更高的卷取速度旋转的纱线中观察到的相似的性能。
