旋流纺闭合式纤维集聚机构的改进及成纱性能

 为了探究旋流纺新的引纱方法，本文在旋流纺闭合式集聚装置上作了改进，将其设计成附有引纱通道和引纱罗拉的集聚装置。成纱利用引纱方法将汇聚好的纤维束引出来，再利用旋流喷嘴加捻成纱。首先分析改进前后集聚装置的区别和成纱原理，然后通过改变旋流喷嘴的气压配置，对所纺纱线的断裂强力及毛羽两项纱线质量的主要性能指标进行了测试，分析喷嘴气压配置与成纱质量之间关系，并通过扫描电镜来分析纱线结构的变化。发现：这种成纱方法可以纺制出普通纯棉纱线，加捻气压仍然对纱线质量影响较大，纱线的外观和改进前的纱线不同。本结果为研究旋流纺新型汇聚装置提供参考。

Modification on closed fiber-converging device of swirl spinning and yarn performance

In order to explore a new method to lead yarn in the swirl spinning,the closed fiber-converging device of swirl spinning is improved in this paper.The converging device is designed with a leading yarn channel and pulling rollers.The yarn is formed by fetching the converged fiber bundles and then twisting the bundles through the swirl nozzle.This paper compares the fiber-converging device before and after modification and the principles of yarn forming,analyzes the differences in properties and structures of...
