清梳工序中棉结的研究分析

Study and Analyses of Neps in Picking and Carding Process

重点研究清梳工序中棉结的变化情况及减少棉结的措施。测试了各工序棉结的分布情况,介绍了棉结的概念和半制品中棉结的检测方法,分析了轧工方法、清梳各工序、纤维的成熟度和细度以及原棉中的短绒对棉结的影响。指出:降低清梳工序棉结就要合理制定混配棉指标、改进清梳工艺流程、重视梳棉和精梳。梳棉工序通过控制落棉、减少搓擦、控制生条短绒率、提高纤维平行伸直度、采用新工艺和严格控制温湿度等措施可以有效控制棉结的产生。

Measures of reducing neps and its change situation in picking and carding process were studied as key points. Neps distribution situation in each process were tested. Concept of neps and test method in semi-product were introduced. Effect of cotton ginning,picking and carding process, fibre maturity ＆ fineness ＆ short fibre in raw material were analysed. It is pointed out that in reducing neps in picking and carding process blending and assorting indexes should be made rationally,technological process should be modified, carding and combing should be paid attention to. Through controlling noil, reducing rub, controlling carded sliver short fibre content and increasing fibre parallel and straightness, adopting new processing, controlling temperature ＆ humidity strictly et al, neps could be controlled effectivelv.
