ANALYSIS OF DIFFERENT BLEND FABRIC DYEING WITH REACTIVE AND DISPERSE DYES AND EVALUATE COLOR PARAMETERS AND FASTNESS PROPERTIES
Abstract
The main object of this researh work is to analyze different blend fabric dyeing with reactive and disperse dyes and evaluate color parameters. In this research work Remazol reactive dye, Tricon diperse dye and four types of blended fabrics were used like as 50/50 polyester viscose blended fabric (Blend A), 65/35 Polyester Cotton s/j blended fabric (Blend B), 60/40 CVC s/j blended fabric (Blend C), and 80/20 chief value cotton (CVC) s/j blended fabric (Blend D) for dyeing with light, medium & dark shade. The different blend fabrics 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 after soap wash. Beside this washing and rubbing fastness levels of the dyed blended fabrics were investigate. It was 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 the blends. Key words: blended fabrics, color strength, washing and rubbing fastness, Spectrophotometer, cotton and polyester dyeing.
