Contribution of ring spinning process to the fibre-shedding behaviour of cotton yarn during knitting

摘要

Ring spinning process adds up short fibres in yarn structure. But the nature of short fibres and their length distribution completely differ from fibre fly that are deposited in cone unwinding zone and knitting zone. Fly from cotton carded yarn is basically shorter, very fine in nature and highly immature. The characteristics of fibre fly and its length distribution are almost similar in these zones. Fibre-shedding behaviour of carded yarn is studied before and after cone winding operations by changing some of the winding parameters based on three factors—three-level Box Behnken Design of Experiment. It is observed that there is an increase in average fibre-shedding (g) of individual cone samples over ring cop in most of the cases.
