Acid dyestuff

Acid dyestuffs are a class of synthetic dyes primarily used to color natural fibers like wool, silk, and nylon. They work by forming a chemical bond with the fiber, resulting in vibrant and wash-fast colors. Acid dyestuffs are popular in the textile industry, producing a wide spectrum of hues with excellent color clarity.
