MICROWAVE ASSISTED DYEING OF COTTON FABRIC WITH REACTIVE DYES

Abstract

Microwaves are a form of electromagnetic waves, like other radio waves. Microwave technology, which provides homogeneous and fast heating, attracts attention as an ecofriendly alternative new method in industrial processes. So, the use of microwave technology in many industries has become widespread recently. In this study, conventional heating and microwave heating in the exhaust dyeing of bleached cotton fabric with reactive dyestuff were studied. The aim of this study is dyeing of cotton fabric with reactive dyestuff using microwave media to save time, energy and money. The conventional reactive dyeing process time is 90 minutes. The L level dyeing time in microwave media was completed in 10 minutes, and a deeper color was obtained. It has been observed that the cotton dyeing process time with microwave heating is significantly reduced compared to the traditional cotton dyeing process.
