Therefore, the invention adopts a fixed sequence twisting device, and not only adopts a mode of combining the yarn guide bar grid with the V-shaped control groove, but also plays a role of effectively controlling the ordered arrangement of single yarns with various colors in multi-color and multi-strand yarns. Meanwhile, through the mechanical analysis and the plying and twisting experiments of the plied yarn effect by the geometric configuration of the single yarns of various colors, the plied yarn structure and twisting in the plied yarn, the hollow plied yarn can be formed only if the number of the single yarns subjected to one-time plying and twisting in the plied yarn production does not exceed five, so that the solid plied yarn is prevented from being formed, and the single yarns of various colors are effectively controlled to be arranged in sequence. If the product needs more than five folded yarns, a multiple twisting process of first twisting and then second twisting can be adopted to achieve the effect of sequential arrangement.
Compared with the prior art, the invention can weave a plurality of strands of yarns which are regularly arranged in color, solves the technical problem of disordered color sequencing of the multi-color multi-strand yarns, eliminates color grade defects in the fabric and can effectively ensure the product quality of the multi-color multi-strand yarns.
