自伸长涤纶纤维及其制备方法和由该自伸长涤纶纤维得到的混纤纱或织物
摘要：
本发明提供一种自伸长涤纶纤维及其制备方法，和由该自伸长涤纶纤维制得的混纤纱或织物。所述的自伸长涤纶在180℃、30分钟下测定的自伸长率为大于0、小于或等于15％，在放置1个月以上的时间后，仍可保持其自伸长率，并且具有较高的上染率。含有该自伸长涤纶的机织物或针织物，具有很好的蓬松丰满感，而且在机织物或针织物的表面给人以柔软细腻舒适的感觉，光泽性很好，大大提高了机织物或针织物的附加价值，增加了经济效益。
摘要（英）：

The present invention provides a self-extending polyester fibre and its preparation method, and the blended filament yarn or fabric made up by using said self-extending polyester fibre. The automaticextension rate of the self-extending polyester fibre which is measured at 180 deg.C within 30 min, is greater than zero and less than or equal to 15%, after it is stored for above 1 month its automatic extension rate also is retained, and it has high rate of dyeing. The woven fabrir or knitted foods containing said self-extending polyester have good loftiness and glossiness.
