A Study on Dyeing with Reactive Yellow 15 Dye and Its Effect on Modified Mulberry Silk /Wool Blended Fabric

Pallavi Lakhchaura, Dr. Sandeep Bains

Abstract :

A study on dyeing with reactive yellow 15 dye and its effect on modified mulberry silk/wool blended faic was conducted. In this study enzymatically unmodified and enzymatically modified samples were dyed under optimized dyeing conditions viz. dyeing pH 6, dyeing time 60 min, dyeing temperature 800C and dyeing concentration 4% (owf). The optical density, CIE Lab K/S values and colour fastness properties of both enzymatically unmodified and enzymatically modified faic were compared. It was found that the enzymatically modified dyed samples showed significantly increased dye absorption when compared to the enzymatically untreated dyed samples whereas no significant difference in the CIE Lab and K/S values of enzymatically unmodified and modified dyed samples was observed. The enzymatically modified showed slight change in the colour fastness properties.
