Abstract

Combing is a process by which the quantity of short fibers and remnants of impurities in a carded or drawn sliver are minimized, resulting in a cleaner sliver with a more rectangular staple diagram. This process aligns the vast majority of constituent fibers in a straightened and parallel state. Combing enables the spinning of yarns with fine counts, reducing irregularities and creating a clear appearance. Additionally, combing results in stronger, smoother, and more lustrous yarns.

In the spinning process, combing improves raw material quality by removing noil. The extraction of noil significantly impacts cost, and there's a limit to how much noil can be increased. Thus, from both an economic and quality perspective, selecting the optimum level of noil extraction is necessary. To achieve this, attempts were made to reduce the neplevel in the combing process by adjusting the noil percentage. Trials were conducted using three different noil percentages—18%, 20%, and 22%—to produce yarns of counts 35sCW (Tex 16.85) and 40s CH (Tex 14.76) respectively, maintaining the same process parameters from the blow room to the ring frame, as well as in mixing.
