The automatic knitting machine uses knitting needles to form loops of various raw materials and types of yarns and then connects them into knitted fabrics through strings. The knitted material is soft, has excellent wrinkle resistance and breathability, and has greater extensibility and elasticity, so it is comfortable to wear. In addition to being used for consumption and decoration, knitted products can also be used in fields such as industry, agriculture, medical care, and national defense. Knitting is divided into two categories: manual knitting and machine knitting. Hand knitting uses stick needles, which have a long history, exquisite skills, and flexible flower shapes, so it has been widely spread and developed among the people.
According to different process characteristics, knitting production can generally be divided into weft knitting and warp knitting. In weft knitting production, after the raw material has been wound, the package yarn can be directly put on the machine for production.
Each yarn is sequentially laid on the needles of the weft knitting machine in the weft direction, forming a weft-knitted fabric. In warp knitting production, the raw materials are wound and warped, and the yarns are arranged in parallel and wound into warp beams, which are then produced on the machine.
The yarns are unwound from the warp beam, and each yarn is placed on one or at most two knitting needles of the warp knitting machine in the longitudinal direction, forming a warp knitted fabric. There is also a method of combining weft knitting and warp knitting on some knitting machines. At this time, two sets of yarns are arranged on the knitting machine, one set is covered by the warp knitting method, and the other is covered by the weft knitting method. Loops formed from the same yarn are arranged in the weft direction in weft-knitted knitted fabrics, and in the warp direction is warp-knitted knitted fabrics.
