摘要
本文介绍了PBT/PET共混纤维的性能。在DSC测试中发现,该共混纤维的两组分在晶区是不相容的,而在无定形区两组有是相容的;共混纤维克服了PBT纤维的自伸长现象,改善了卷装成型及两组分性能的加和性,使共混纤维的最大拉伸比及初始模量提高了,并改善了染色性和手感。接着介绍了PBT/PET复合纤维无需变形加工,可制得具有自卷曲的高伸缩性及两组分纤维性能的加和性,手感柔软、染色性能优良的纤维。最后介绍嵌段共聚PBT纤维性能,及其生产公用工程消耗低、经济性好以及弹性可调性等优点。另外,还介绍了共混、复合及嵌段PBT纤维国内外发展情况及其在仿真丝、弹性织物及弹力缝纫线等应用情况。
The PBT derived synthetic fibers including PBT/PET blend fiber. PBT/PET composite fiber and PBT block copolymer fiber are introduced in regards to their properties and advantages, their applications in silk-like and elastic fabrics as well as sewing threads are described with their developments in home and abroad.
