织厂经纱断头成因分析

本文所采用的研究方法主要是在上海某几个纺织厂中循着织厂工艺流程,采集了近2000根实际经纱断裂端,藉助于扫描电镜观察其中纤维的断裂形态,以探究其断裂机理;并获得减少断头的参考。从扫描电镜照片的观察中见到,纤维断裂端显示出通常的螺旋线分裂状断裂形态。此外纱线在络筒,整经、织造等不同工序中的断裂模式是有所区别的。根据布机上断裂纱线中的纤维断裂端的形态分析,可以帮助判断造成纱线断头的原因,并推断前道工序工艺配置是否合理。由此可以从提高织物产质量出发,为最佳工艺的选择提供依据。

ANALYSIS OF WARP FRACTURE IN WEAVING MILL

Nearly 2 000 broken ends of the warps were collected from the different pro- cessing stages in the weaving mills in Shanghai,and the fracture morphologies were examined by the scanning electron microscopy,The fracture mechanism was discussed. The broken ends showed that the normal helical splitting fracture morphology could be seen,and besides,different broken models were found at coning,beaming and weaving processing stages.The analysis of the fracture morphology of,the warp yarn on weaving machine can help to check the reason of fracture and to condider whether it is reasonable for the previous processing,consequently it can be used to choose the best technical parameters to produce fabrics of good quality.
