实验方法研究纱线可织性

主要讨论影响经纱可织性的因素以及研究经纱可织性的实验方法。原纱质量、经纱准备、织造条件是影响经纱可织性的重要因素。经纱的可织性可通过改变纺纱参数、纺纱技术来提高，但对经纱可织性有决定性的是织前准备。通过织前准备，特别是浆纱工序可充分地提高可织性。分析表明给定浆纱的可织性可通过浆纱强伸性、浆纱耐磨性、织造模拟后浆纱毛羽变化、织造模拟后浆纱缠结分离力等指标来预测。

Studies of the Yarn Weavability by Experimental Methods

This paper mainly deals with factors affecting warp weavability and tester methods researching warp weavability. The weavability of the warp yarns is largely influenced by the quality of grey yarn, the quality of preparation and the weaving condition. The weavability of the warp yarns can be improved by changing spinning parameters, spinning technology. However, the yarn must have a certain minimum quality. Besides this, the weavability can be substantially improved by making a choice of suitable size materials and sizing process. We can use empirical approach, statistical approach and instrumental approach to predict the weavability of the warp yarn. The weavability of the warp yarns can be predicted by sized yarn tensile breaking strength, breaking elongation, abrasion resistance, hairiness and separating force.
