a process performed by knitting machines in the production of knitted fabrics or garments. Looping involves bending the yarn into loops and passing new loops through those already formed. The process is essentially the conversion of yarn into knitted goods.
There are two methods of looping. The first involves bending the yarn on the needles of the machine and then pulling it through the loops formed. The size of the loops is fixed prior to their formation, during the bending step. In the second method, the yarn is taken up by the needle and pulled through an old loop. Thus, the new loop is formed without preliminary preparation, that is, without bending. The size of the loop depends on the length of the pull-through, the yarn tension, and the tightness of the loops formed.
