Dyeing of cotton fabric with reactive dye using glutaraldehyde.

This article explores the process of dyeing cotton fabric with reactive dye using glutaraldehyde as a crosslinking agent. Reactive dyes are commonly used for dyeing cotton fabrics because they create permanent color by forming covalent bonds with the fibers. Glutaraldehyde is a powerful crosslinking agent that can enhance dye uptake and improve fixation on the fabric. The article provides detailed instructions for the dyeing process using glutaraldehyde and discusses the benefits and challenges associated with this method. It also examines the effects of crosslinking agents on the physical properties of the dyed fabric, finding that glutaraldehyde improves stiffness, crease recovery, rubbing fastness, and light fastness. Additionally, replacing alkali with glutaraldehyde reduces hydrolysis of reactive dyes and makes the process more eco-friendly. [Extracted from the article]
