Study on Reactive Dyeing of Cotton Fabric using an Ethanol Solvent System.

Abstract

In this study, an ethanol–water mixture is used as a dyeing medium for cotton fabric with reactive dyes without using salt, soda, or any other auxiliary chemicals. After dyeing, several fastness properties were evaluated, including: Color fastness to wet and dry rubbing Color fastness to washing Color fastness to alkaline and acidic perspiration The results were found to be very similar to those of conventionally dyed samples using water-based systems for reactive dyes. Since ethanol is a green solvent, and the ethanol– water mixture is recyclable, it presents a sustainable alternative to traditional cotton dyeing methods. This approach is expected to contribute positively toward eco-friendly and sustainable textile processing by reducing the environmental impact associated with water and chemical consumption.
