Reactive Dyes and Their Application
This first part of Chapter 5 covers the background to the development of reactive dyes, explains the history which led to their belated discovery and gives the reasons for their present importance. The nature of the dye-fiber bond is covered as well as the processes by which it is formed. The overall procedure for reactive batch dyeing, which involves the three steps of dyeing, fixation and was...
متن کاملCompatibility Testing of Reactive Dyes
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 e...
متن کاملContact allergy to reactive dyes in footwear.
Reactive dyes have been used in the textile industry for the past 60 years; they colour fibres brightly and are highly wetfast. They consist of a direct colourant (an azo, anthraquinone or phthalocyanin derivative group) connected to a reactive group, which is capable of linking through covalent bonds to the amine or sulfhydryl groups of proteins (1). We report a case of a delayed contact hyper...
متن کاملEvaluation Of Aftertreatments For Reusing Reactive Dyes
The use of reactive dyes has increased rapidly due to outstanding properties, growing consumption of cellulosic fibers, and decrease in the production of other application classes of dyes for cellulosics because of cost and health hazards. However, reactive dyes cause the greatest effluent problems for the dye industry. This study explored reusing these dyes in which the residual dyeings were d...
متن کاملDyeing of Indian wool with reactive dyes
Wool fibres have been chemically modified by reduction I chlorination under acidic pH Ipre-swelling in conc. formic acid prior to their dyeing with indigenous reactive dyes of different molecular configurations to enhance the reactive dye uptake on wool fibre substrate. The pretreatment processes are inexpensive, less harmful and less time consuming as against the use of imported special wool r...
