Enzymes are protein molecules that act as biological catalysts to facilitate chemical reactions in living organisms. Enzymes in the dyeing process can be used in various stages, such as in the pre-treatment of the fabric to remove impurities, in the dye bath to enhance the uptake of the dye, and in the post-treatment to fix

Direct dyes are water-soluble anionic dyes and retain sulphonic acid groups in their structure. They are directly taken up by the fibers. In 1883, J. Walter of Geigy first discovered the synthetic direct dye, which was Direct Yellow 11. In 1956, SDC defined direct dye as, “Anionic dyes substantive to cellulose when applied from an

Do you know why acid dyes are called that? Mostly acid dyes you will get are carboxylic or sulphuric acid salts. Often, they are applied from an acidic bath. That’s why they are called “acid dye”. Though acid dyes possess pretty good light fastness, the wet fastness is not that good. In this article, we

A dispersant or dispersing agent makes the dispersion process more stable and easier for a solid material dispersed in a liquid. The dispersing agent has an effect on the rate of dyeing. It increases the solubility of the disperse dye as well as increases the dyeing rate up to a certain time. But after that certain value,

Viscose is a regenerated fiber that combines both natural and man-made fibers. Viscose can be dyed in loose, hank, or fabric form with Reactive dye, Direct, and Vat dyes. Viscose has a smooth and silky appearance with extreme breathability like cotton. In this blog post, we’ll take a look at the process flow chart for viscose fabric dyeing.
