Compatibility testing of reactive dyes

Abstract

The present work deals with the ways of testing the compatibility of reactive dyes with cotton in different textile industries in Bangladesh. This report includes three laboratory trials that were carried out for three different reactive dyes to check the compatibility for use in a dye recipe on cotton knitted goods. In this study, Spectrophotometric analysis was conducted and the fixation of each dye was determined by using computer colour matching system. The results found from different industries were analysed and discussed. This testing can be used as a tool for selecting good quality dyes as well as to reduce dyeing cost and hazard. Finally few recommendations are highlighted to overcome the problem of selecting better quality dyes for cotton goods in textile industries in Bangladesh.
