Changes in warp wire tension during the opening process

    The inner connection between the changes in warp wire tension due to tensile deformation during opening is extremely complex. In the process of opening, the tension of the warp wire is constantly changing. During the opening period, the tension of the warp wires changes from small to large; during the stationary period, the tension of the warp wires is larger and more stable; during the closing period, the tension of the warp wires changes from large to small. In the weaving process, in order to facilitate the movement of the sword belt and reduce the resistance of the card weft, are generally used on the upper layer of the warp wire tension is small, the lower layer of the warp wire tension is larger unequal tensions stranded mouth.
