VARIATION IN LINEAR DENSITY OF COMBED YARN DUE TO DYEING WITH REACTIVE DYE IN DIFFERENT SHADE PERCENTAGES

Though yarn dyeing is a significant part of wet processing, it still has some major obstacles. It loses its weight as well as strength due to wet treatment. A study on the changes of linear density in combed yarn due to different shade percentages of reactive dye has been conducted and the results are statistically analyzed. Remazol Red RR, Remazol Yellow RR and Remazol Blue RR were used for this experiment. The study reveals that dye shade percentage effects on the linear density negatively. Before 2.5 % shade the yarn loss is greater and after 3.5 % shade linear density also decreases. 2.5 % to 3.5 % shade percentage can be taken as the range where loss of linear density is much less than the other percentages. The lowest loss percentage was found for 3 % shade for every dyestuff among which Remazol Red RR was the least
