What is different between reactive dyes and acid dyes?
Reactive dyes and acid dyes are both types of dyes used in the textile industry, but they have different properties and uses: Chemical Composition: Reactive Dyes: These reactive Dyes Manufacturers in India contain reactive groups that form a covalent bond with the fiber molecules, usually cellulose fibers like cotton, linen, and rayon. They are often used for dyeing natural fibers. Acid Dyes: Acid dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon, and modified acrylic fibers from neutral to acid dye baths. Application: Reactive Dyes: They require a specific pH and temperature to bond with the fiber. Typically, a reactive dye bath is alkaline, and the dyeing process often involves a series of steps including pre-treatment, dyeing, and after-treatment. Acid Dyes: Acid dyes are applied in an acidic dye bath, and they do not require high temperatures for application. They are commonly used for protein fibers like silk and wool. Color Fastne...
