Q » Explain the process of Reactive dyes.
31 Oct, 2025
A » Reactive dyes are a class of highly colored organic substances that create a covalent bond with fiber molecules, commonly used in dyeing cellulose fibers like cotton. The process involves three stages: dyeing, where the dye is applied to the fabric; fixation, where the dye reacts with the fiber under alkaline conditions; and washing, to remove unfixed dye and ensure color fastness. This method ensures vibrant, long-lasting colors.
