摘要
(CN106283260) 本​发明​涉及​种​多孔​超​柔软​聚酯纤维​FDY​丝​及其​制备​方法,将​改性​聚酯​采用​多孔​喷​丝板​纺丝​制得​多孔​超​柔软​聚酯纤维​FDY​丝;多孔​喷​丝板​上​喷​丝​孔​的​排列​方式​为​椭圆形​排列,即​喷​丝​孔​的​孔​中心​位于​同心​椭圆​上,同心​椭圆​为​系列​椭圆,所有​椭圆​的​长​轴​共​线,且​短​轴​共​线。多孔​超​柔软​聚酯纤维​FDY​丝​由​改性​聚酯​切片​经​计量、挤出、冷却、上油、拉伸、热定型​和​卷绕​制得,改性​聚酯​的​制备​方法​为:对苯二甲酸​与​乙二醇​反应​制得​对苯二甲酸​乙二醇​酯,加入​对苯二甲酸​与​含​支链​的​己​二醇​反应​制得​的​对苯二甲酸​二元醇​酯,继续​反应​得到。本​发明​制得​的​纤维​性能​优良,线​密度​偏差​率≤0.5%,断裂强度​CV​值≤4.0%,断裂​伸长​CV​值≤8.0%,条​干​不​匀​率​CV≤2.0%。
