The weaving principle of weft knitted fabric is:

Knitted fabric is made up of countless loops interwoven vertically and horizontally, and each loop can be completed by the process of knitting needles. Knitting needles are generally divided into three types: hairpin needles, latch needles and compound needles.

A Hand-woven looping process: The loop-forming principle is exactly the same for both machine and hand-woven knitted fabrics. One of the needles is used to wear a row of old loops, and the other needle just goes through the old loops and pulls the freshly wound yarn out to form new loops.

B Mechanical loop forming process: The knitting needles of circular knitting machines are generally latch needles. The loop forming process is as follows: 1. At the beginning, the loop is in the hook, the knitting needle starts to rise, the loop opens the latch, and the loop is closed. Slide into the needle bar. 2 The needle continues to rise until the loop is completely free of the latch. 3 When the needle rises to a certain level and starts to descend, the yarn is fed into the hook. 4 When the needle continues to descend, the old loop rises relatively and closes the latch, the fed yarn is drawn into an arc, and finally, because the latch is closed, the hook slides out from the old loop and pulls the introduced The yarn is passed through the old loop to form a new loop.
