织机动态经纱张力对比测试分析

Comparative Analysis of the Dynamic Warp Tension on the Loom

为了真实反映织物织造时经纱张力的波动情况,正确评价织机性能,为织机设计制造提供定量化数据,采用虚拟仪器技术研发了经纱张力动态测试系统;探讨了织造过程中经纱张力波动曲线的测试方法和影响因素。对通过该系统两种织机、两种织物的经纱动态张力曲线进行对比测试分析,指出:不同织物、不同织机,其经纱张力的波动规律并不一致,在建立电子送经等控制系统时,采样点的选取位置和系统参数设置等应区别对待,这样才能使织机运行达到最佳状态。

In order to have a real display of the tension variance of the warp in weaving process, to have a correct evaluation of the loom performance,and to have a ration data for future loom design,a new dynamic warp tension test system is introduced by mean of virtual technology. Approach is done into the the testing method of the warp tension variance and the related impacting factors. Comparative analysis is done to the two dynamic tension curves regarding the two looms and the two fabrics. Conclusion is made that warp tension variance is dependent upon the fabric and loom varieties. When electric warp let-off is established, it is necessary to have different sampling location and different specification configuration. Only by doing so, can loom performance be optimized.
