异经异纬化纤系列产品的开发

Development of Different Warps Different Wefts Chemical Fiber Series Products

探讨生产细特涤纶、Modal涤纶混纺纱异经异纬产品的关键工艺技术。通过生产实践,认为浆纱工序是关键,尤其是浆料配方要优选,选择K2000复合变性淀粉代替PVA-205MB效果较好,且对防静电剂和平滑剂等助剂要调整;为便于穿筘穿综,在Modal涤纶混纺纱的浆槽中加着色剂;浆纱落轴时要在两种经纱间压绞线,减少并头和综穿错;织造时将两种经纱的开口角错开,减少静电现象。采取以上措施后,织机效率能达到88%。

Key processing technology of fine count polyester Modal polyester blended product of different warps and different wefts were discussed. Sizing process is considered as the key, especially optimizing size formula. Choosing K2000 compound modified starch instead of PVA-205MB has better effect, and electrostatic resistant agent, smooth agent and other aids should be adjusted. Colorant was adding in sizing box of Modal polyester blended yarn to easy to reed-in and drafting. Pressure line should be added in two kinds of warps in beam doffing to reduce wrong drafting, Shed angle of two kinds of warps should have a interleaving to reduce static effect. Through these measures, loom efficiency can reach above 88%.
