壳聚糖/竹纤维/精梳棉赛络集聚纺14.8 tex纱生产实践

Production Practice of Chitosan/Bamboo Fiber/Combed Cotton Siro-compact Spinning 14.8 tex Yarn

为提高壳聚糖/竹纤维/精梳棉12/50/38赛络集聚纺14.8 tex混纺纱的成纱质量,介绍壳聚糖纤维、竹纤维、精梳棉的性能及其混纺工艺流程;详述成条、并条、粗纱、细纱、络筒工序的生产工艺和质量控制指标,分析壳聚糖含量的控制及检测方法;探讨梳理原则、牵伸配置、捻接工艺参数、温湿度控制等工艺难点及采取措施。指出:壳聚糖/竹纤维/精梳棉12/50/38赛络集聚纺14.8 tex混纺纱结合纤维功能与赛络集聚纺工艺,根据3组分纤维的不同特点采用3道并条混合方法,并条工序熟条检测壳聚糖含量,保证纤维配比准确;通过优化各工序工艺参数,使成纱质量满足了客户需求。

In order to improve the quality of chitosan/bamboo fiber/combed cotton 12/50/38 siro-compact spinning 14.8 tex blended yarn,the properties and blending process of chitosan fiber,bamboo fiber and combed cotton are introduced.The production process and quality control indexes of slivering,drawing,roving,spinning and winding processes are described in detail,and the control and detection methods of chitosan content are analyzed.Process difficulties such as the carding principles,drafting configuration,process parameters of splicing,temperature and humidity control and corresponding measures are discussed.It is pointed out that the chitosan/bamboo fiber/combed cotton 12/50/38 siro-compact spinning 14.8 tex blended yarn is combined with the fiber function and the siro-compact spinning process,the 3-strand blending method is adopted according to the different characteristics of the three components of fiber,and the content of chitosan is detected with the processed strips to ensure the accuracy of the fiber ratio.By optimizing the technological parameters of each process,the yarn quality meets the customer’s demands.
