In addition to woven into a variety of grey fabrics, cut and sewn into a variety of knitwear, the formed products can be directly woven on the machine to make fully formed or partially formed products. The forming process saves raw materials, simplifies or eliminates cutting and sewing processes, and improves product performance. Knitting production is rapidly developed due to short process, strong adaptability of raw materials, rapid change of varieties, wide range of products, low noise and low energy consumption. Since the 1970s, the productivity of knitting machines has been greatly improved. For example, a circular weft knitting machine (tongue needle) can weave about 3,000 stitches per minute. The warp knitting machine has a width of 427 cm, which is the highest per minute. Weaving 2000 coils, the speed of a single-cylinder sock machine can be up to 1000 rpm. The use of electronic technology to control the work of the knitting machine increases machine efficiency. Various positive yarn feeders can be installed on the machine to improve product quality. Attaching some mechanism to the machine can weave knitted fabrics of various organizational structures and different uses: such as applying needle selection mechanism to make the knitting needles work according to a pre-arranged procedure to weave jacquard knitted fabrics; applying the combing mechanism to feed the loose fibers into the weaving Needle to weave a plush knit; apply a weft insertion device to weave the weft knitted fabric. There are more than 350 kinds of knitting machines. With the development of new chemical fiber varieties and finishing processes, the characteristics of the knitted fabrics such as scratching, ironing and abrasion resistance are improved. The application of finishing techniques such as brushing, sanding, shearing, ginning and pleating makes the variety of knitwear more extensive.
Knitting technology has been extended to other textile production areas, such as applying the knitting loop method to the weaving machine for segment weft insertion, and connecting the weft yarns with the stitches to the string knitting sleeves instead of the traditional picking movement. The weaving speed is increased, which is a weaving and knitting machine.
