ANALYSIS OF DIFFERENT BLEND FABRIC DYEING WITH REACTIVE AND DISPERSE DYES AND EVALUATE COLOR PARAMETERS AND FASTNESS PROPERTIES

摘要

The main object of this researh work is to analyze different blend fabric dyeing with reactive anddisperse dyes and evaluate color parameters. In this research work Remazol reactive dye, Tricon diperse dyeand four types of blended fabrics were used like as 50/50 polyester viscose blended fabric (Blend A), 65/35Polyester Cotton s/j blended fabric (Blend B), 60/40 CVC s/j blended fabric (Blend C), and 80/20 chief valuecotton (CVC) s/j blended fabric (Blend D) for dyeing with light, medium & dark shade. The different blendfabrics were dyed by batch process with the help of lab dyeing machine keeping material to liquor ratio 1:10.Spectrophotometer was used to find out the color strength and amount of dye in the fabrics before and aftersoap wash. Beside this washing and rubbing fastness levels of the dyed blended fabrics were investigate. Itwas found that, considering all the blends the k/s value and fastness properties of blend D is better for light,medium and dark shade. But if it is considered only dark shade, then k/s value of blend B is higher than all theblends.
