Knitting process characteristics
According to different process characteristics, knitting production is divided into two categories: weft knitting and warp knitting. In weft knitting production, after the raw material is wound, the yarn can be produced directly on the machine. Each yarn shuttles along the weft direction on each knitting needle of the weft knitting machine in turn to form a weft knitted fabric. In the production of warp knitting, the raw materials are wound and warped, and the yarns are arranged in parallel and wound into warp beams, and then produced on the machine. The yarns are withdrawn from the shaft, and each yarn is draped longitudinally on one or at most two needles of the warp knitting machine to form a warp knitted structure. There are also methods of combining weft and warp knitting on some knitting machines. At this time, two groups of yarns are arranged on the knitting machine, one group is laid by the warp knitting method, and the other group is laid by the weft knitting method, and the knitting needles form loops together to form a knitted fabric. The loops formed by the same yarn are arranged along the weft direction in weft-knitted fabrics and along the warp direction in warp-knitted fabrics.
