Process of making yarn from two types of polyester

摘要：

A soft stretch yarn produced by spinning yarn of conjugate fibers including two types of polyester in which one component is PTT at a take-up velocity of at least 1200 m/min, drawing at a drawing temperature of 50 to 80° C. at a draw ratio such that the drawn yarn tensile elongation is 20 to 45%, and then heat setting.

摘要（中）：

通过将复合纤维纺丝而成的软拉伸丝，该复合纤维包括两种类型的聚酯，其中一种成分为PTT，卷取速度为至少1200m / min，拉伸温度为50〜80℃，拉伸倍率使拉伸丝拉伸伸长率为20〜45％，然后进行热定型。
