摘要
介绍了用纽马格公司双组分复合生产线生产的涤纶并列型三维卷曲中空纤维的生产技术。讨论了两种切片的特性粘数、纺丝温度、侧吹风、后拉伸倍数、松弛定型等工艺对纤维性能的影响。结果表明：两种切片的特性粘数差对中空度的影响较大，应保证在０．１０～０．１２ｄＬ／ｇ较好，后拉伸倍数影响纤维的卷曲数，一般控制在５左右，松弛定型温度可根据产品的用途在１３０～１６０℃调整。
The technology for side by side 3 dimensional crimped hollow PET fiber produced by Neumag bi component production line was introduced. The influences of viscosity, spinning temperature, quenching air, after drawing ratio, crimp, shrink setting of two components on fiber properties were discussed in detail. The result shows that the viscosity of two different chips,better in the range of 0.10￣0.12 dL/g, has more influence on hollowness, and after drawing ratio which affects fiber crimp number should be generally controlled at about 5. The shrink setting temperature would be adapted in the range of 130￣160℃ to the fiber end use.
