Study of Effect of Spinning Process Variables on Fibre Length Parameters Using Taguchi Method
نویسندگان
چکیده
The effect of drafts at different stages of spinning process on fibre length distribution of slivers has been studied by using Taguchi Method and ANOVA technique. The L8 mixed orthogonal array was used to work out eight different slivers. Two different lap hanks, four different card drafts and two different draft/doublings at breaker and finisher were selected for the study. The fibrograph length measurements in terms of 2.5 %, 50 % and 66.7 % span lengths and mean lengths (mean length and upper half mean length) were studied. The 50% span length (SL) and 66.7% SL give an indication of fibre hooks in the sliver. These span lengths in card sliver first decrease and then increase with drafting at breaker and finisher sliver due to removal of hooks.
