Background

In the operation process of the air jet loom, warps and wefts are interwoven with each other according to a certain rule to form fabrics such as plain weave, twill and yarn-dyed plaid. The interweaving of the warp and the weft firstly needs to enable the warp to form a shed through an opening device, then enables the weft to be introduced into the shed through a weft insertion device, and finally enables the weft to be inserted into a weaving opening through a beating-up device to form a fabric; in the process of shedding by the shedding device, the warp yarns are continuously subjected to transverse stretching, so that the tension of the warp yarns is continuously changed, and therefore, the shedding has a large influence on the warp yarn deformation and the warp yarn tension, and particularly the production of high-density and heavy fabrics. The warp deformation can increase the end breakage rate and reduce the weaving efficiency; the large warp tension fluctuation is unfavorable for the strength and fatigue strength of parts of the weaving machine, accelerates the failure of parts and increases the weaving difficulty.
