Abstract

Combing is the key processes for the quality improvement of spinning cotton fiber by extracting short fibres less than half an inch in length. The type of feeding system with varying machine setting has effect on the quality and the production rate of comber. This paper deals with the study of transfer of good fibres into the noil and transfers of short fibres into the sliver. For these studies, medium staple cotton variety of Shankar 6 has been taken and processed with both feeding systems of comber by varying the settings of fed length, top comb and detaching roller. The quality distribution of feed lap, noil and combed sliver has been evaluated under Advanced Fibre Information System (AFIS). Better fibre control was observed with backward feeding as compared to forward feeding. The transfer of longest fibre into the noil is observed less by 12.5% and the length of shortest fibre into the comber sliver is also less observed by 4.7% by keeping constant top comb index with varying feed length and detaching distance of both feeding system when compare to other variables.

Keywords: Comber, backward feed, forward feed sliver, noil, AFIS.
