喷气织机经位置线对织造效率与织物质量影响研究

Influence of Warp Position Line on Weaving Efficiency and Fabric Quality of Air Jet Loom

针对喷气织机在织造生产中经位置线配置的重要性,本文以实验室JAT-810丰田喷气织机为例,主要研究喷气织机经位置线对织造效率与织物质量的影响。首先对其经位置线进行量化,并通过调节经位置线各参数,分析梭口的变化形态,计算上下层经纱的张力和织物紧度的变化,并分析了经位置线参数的改变对织造效率和织物质量的影响。研究结果表明,随着后梁高度的上升、梭口高度的下降及梭口长度的增加,织物的纬密增加,纬向紧度E w和织物的总紧度随之增加,说明后梁越高,织物的紧度越好。该研究对喷气织机织造经位置线的配置具有一定的参考意义。

In view of the importance of warp position line configuration in air-jet loom weaving production,this paper takes the laboratory JAT810 Toyota air-jet loom as an example to study the influence of warp position line on weaving efficiency and fabric quality.First of all,the warp position line is quantified.By adjusting the parameters of warp position line,the change of shed shape is analyzed,and the change of upper and lower warp tension and fabric tightness is calculated,and the influence of warp position line parameter change on weaving efficiency and fabric quality is analyzed.The results show that the weft density of the fabric increases,and the weft tightness E w and the total tightness of the fabric increase with the increase of the back beam height,the decrease of the shed height and the increase of the shed length.It indicates that the higher the back beam is,the better the fabric tightness is.The research has a certain reference significance for the configuration of warp position line in air-jet loom weaving.
