短纤维单纱捻度测试方法的研究

Study on Testing Method of Twist of Short Fiber Single Yarn

测试短纤维单纱捻度的方法目前主要有直接退捻法、1次退捻加捻法和2次退捻加捻法,但这3种方法检测结果有一定的差异。在同一标准大气环境下使用同一台仪器、同一种纱线分别用直接退捻法、1次退捻加捻法和2次退捻加捻法测试短纤维单纱的捻度,通过试验过程及数据结果的分析来比较这3种方法的差异。

There were three methods to test the twist of short fiber single yarn:direct unt wisting method,one-time untwisting and twisting method and two-time untwisting and twisting method.Under the same standard atmospheric environment,using the same instrument and the same yarn,the twist of short fiber yarn was tested by direct untwisting method,onetime untwisting and twisting method and twotime untwisting and twisting method.The differences among the three methods were compared through the analysis of the test process and data results.
