Knitted fabric is made of countless loops, each loop can be completed through the loop forming process of knitting needles. Knitting needles are generally divided into three types: knitting needles, tongue needles and compound needles.
A Hand-knitting process: Regardless of the mechanical and hand-knitted fabrics, the loop-forming principle is exactly the same. One of the needles is used to wear a row of old coils, and the other has just passed through the old coils and pulled the newly-wound yarn to form a new coil.
B. Mechanical loop forming process: The knitting needles of cylinder knitting machines are mainly tongue needles. The loop forming process is as follows: 1 At the beginning, the loop is in the hook, the knitting needle starts to rise, and the loop opens the tongue. Slide into the needle bar. 2 The knitting needle continues to rise until the loop is completely disengaged from the needle tongue. 3 When the knitting needle rises to a certain level and starts to descend, the yarn is fed into the hook. 4 When the knitting needle continues to descend, the old stitches are relatively raised, and the needle tongue is closed, and the fed yarn is drawn into an arc shape. Finally, because the needle tongue is closed, the needle hook slides out of the old stitch and introduces the The yarn passes through the old loop to form a new loop.
