纯毛纱断裂伸长率预测技术的研究

Research on Prediction Techniques of Breaking Elongation of Pure Wool Yarns

在毛纺加工流程中,纺纱是关键工序。因为纺纱工序的耗资是整个毛条制造的3-4倍,而且织物的质量在很大程度上取决于纱线质量。因此,预测技术的应用对毛纺厂改善纺纱性能和提高纱线质量具有非常重要的经济价值。运用统计软件SPSS对66个批次的纯毛单纱建立了断裂伸长率的预测模型,并且分析了影响纱线断裂伸长率的主要因素。预测技术作为一种质量控制手段具有以下作用:预测纱线品质和纺纱性能,优化毛条选择,调整生产加工工艺。

In the processing of the worsted wool yarn,spinning is a key process,because its cost is 3-4 times than the cost of whole top＇s manufacture process,and the quality of fabric mainly depends on the yarn＇s quality.Thereby,for the worsted wool mills,the application of prediction techniques to improve the quality of the yarn and spinning performance has very important economic value.The prediction model of the breaking elongation of pure wool yarn was set up from 66 batches yarn by using statistic software SPSS 10.0,and the main influencing factors of the breaking elongation were analysed.Prediction technique has the following function as a kind of quality control means：predict yarn quality and spinning performance,optimize top,and adjust processing technology.
