品质指标与纺纱和织物质量之间的关系分析

Analysis of the Quality Index on the Spinning and the Fabric Quality

通过对纤维品质和试验数据可纺性能优劣性的分析,说明了纺纱过程中导致纺纱质量异常现象的关键不是试验数据本身,而是没有认真地对纤维的一些隐性指标做进一步分析,也说明了纤维评等评级、目光检测、手感目测、常规试验仪器检验对纤维检验和纺纱质量控制的重要性。棉纱的试验疵点数据与布面检测疵点数据存在偏离标准和无法捕捉的信息,是未来纺纱试验仪器设备必须改进提高的重要环节之一,纺纱过程中经常出现优质半制品却生产不出优质棉纱的现象再一次说明现代纺纱工艺技术新理念的存在与发展,强调了原料变化与织物组织结构的变化相适应,阐述了改进棉纱某些或某个质量指标是减少纺纱成本、质量控制少走弯路的关键。

Through the analysis of the fiber quality and the spinnability of the test data,it proves that the key factors resulting in abnornal spinning quality depends on the further analysis of the concealed index instead of the test data itself. It also highlights the importance of the faber apprasing system,hand feeling and visual inspection, and the regular testing instruments on the fiber inspection and yarn quality. The deviation of the defects both on the cotton yarn and on the fabric from the norm and some uncertainties leaves some room for the modification of the testers in the future. The common fact that the quality semi-prod- ucts does not always produce quality yarn double proves the exsistance and the development of the theory modern new spinning process. It reinforces that the varieties of the material must be in conformity with the fibric structure and that the key reducing the cost and avoiding the detour in quality control may lie in the modification of certain quality index.
