Development and Application of Reactive Dye Microcapsules for Cotton Fabric Dyeing

Abstract

Reactive dyestuffs used in textile efficiency cotton dyeing are generally applied as a triple mixture. Most of these dyestuffs are supplied to HT machines in powder form without being suitable for automation. 100% of the dyestuffs used in the dyeing recipe applied in reactive dyeing cannot adhere to cotton. Maximum 70% of it adheres to cotton. If the remaining 30% is dye, the substances pass into the water phase. And the dyestuffs that pass into this water phase include substances that are insoluble in water and difficult to purify. It also increases environmental waste burdens. In project scope; By encapsulating reactive dyes with microcapsule technology, it is aimed to reduce the limits of dyes used and reduce environmental waste. And in this context; Dye saving will be achieved.
