Compatibility testing of reactive dyes

Compatibility 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...

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...

Direct compatibility testing.

Despite the rapid development of knowledge it still remains fundamental that mistakes within the ABO and Rhesus systems are responsible for virtually all fatal mismatched transfusions. It therefore cannot be too highly stressed that the careful preliminary grouping of the bloods of all patients for transfusion is of prime importance, irrespective of whether there is a previous record of their b...

Evaluation 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...
