In order to measure accurately the weft tensile force and set the reasonable parameters for rapier loom, it established a new test system with the help of microcomputer and sensors, and achieved the measure for weft dynamic tensile force, and used the sys-tem to measure the weft tensile force of different yarns for TT96 rapier loom.
为了准确地测量剑杆织机引纬时纬纱的动态张力,合理地配置织机的工艺参数,提出了一种新型的纬纱动态张力测试方法,利用单片机和传感器技术等组成纬纱张力检测系统,实现对纬纱张力的动态检测,并运用该系统对TT96型剑杆织机不同纬纱的张力进行了测试和分析。
To help maintain uniform tension in the filling yarns
有助于纬纱张力的均匀。
In weaving, the warp and filling tensions are very important factors and have to be controlled.
在织造过程中,经、纬纱张力是非常重要的参数,必须加以控制。
As the reed moves away from the fell, the cloth at the fell will contract width way under the influence of the tension in the weft produced by the effort of the warp to crimp it.
当钢筘从织口处后退时,由于经纱使纬纱屈曲而产生的纬纱张力会使织物在织口处沿宽度方向收缩。
Neither objective will be achieved if the warp tension is allowed to vary.
如果经纱张力有波动,则均匀的纬纱间距和均匀的纬纱密度两者都不能得到保证。
When this happens, the warp tension will increase, and the pick - spacing will be closer than normal until the roller frees itself.
在这种情况下,经纱张力会增加,纬纱间距会小于正常值。
The shedding and beating- up cause cycle tension variations in the warp yarns.
