Abstract

These studies were conducted in the Department of Fibre Technology, University of Agriculture, Faisalabad during 2001-2002. Various ratios of jute cutting (0, 10, 20 and 30 percent) were added in batch and its effect on jute yarn quality ratio and end breakage was recorded. Different flyer speeds (3400, 3600, 3800 and 4000 rpm) and yam grists {9, 12 and 16 pounds) were also studied. The results showed that effect of cutting percentage and yam grist on quality ratio was highly significant. However, effect of flyer speed and all interactions were non-significant. The highest and lowest values for cutting percentage were 82.83 and 71.19 at zero and 30 percent cutting, respectively. For flyer speed the highest and lowest values of quality ratio were 77.31 and 73 80 for 3600 and 4000 pm, respectively. Similarly, yarn grist of 9 gave better quality ratio (87.93). The results for end breakage showed highly significant effect of flyer speed.
