The effect of hooked fibers on yarn strength is found to have better potency when a fiber tip is presented to the drafting system than a hooked end. When majority hooks are fed as trailing then as leading to the ring frame, better yarn regularity and strength was obtained.
The treatment given to raw material during spinning process through various machines greatly influences not only the quality of spun yarn but also its quantum. Apart from hooks, the fiber parallelization may also have a effect on drafting irregularities.
Moisture content in the raw material especially in cotton is very important due to its direct effect on yarn strength as well as elongation and neps in the yarn, which affects the performance of yarn in warping.
