Abstract: An attempt has been made to find out the influence of the variables affecting loop length as well as to gain an insight into the mechanics of loop formation on a dial and cylinder machine with 1×1 rib gating. For the purpose, the movement of yarn across the knitting elements during loop formation has been studied with the help of a travelling microscope and the loop length has been measured in fabrics produced under different conditions of knitting. The forward movement of yarn inside knitting zone generally continues up to the cylinder knitting point. The backward movement of yarn occurs in atleast two phases-the first phase occurs just after cylinder knitting point and the second phase occurs around the dial knitting point. It has also been observed that the loop length in general increases with the increase in cylinder cam setting, dial cam setting and dial height and decreases with the increase in input tension. A wide range of loop length can be produced on a dial and cylinder machine only by changing the timing of knitting. Generally, the lower loop length results at higher delayed timing.
