Vat dyeing, particularly with indigo, is an ancient and revered textile art form that continues to captivate artists and industrial practitioners alike. At NINGBO INNO PHARMCHEM CO.,LTD., we supply the essential components to master this intricate process, chief among them our high-quality Indigo Blue 94% textile dyestuff.


The unique characteristic of indigo is its insolubility in water. To become a functional dye, it must undergo a chemical transformation into its 'leuco' or 'white indigo' form, which is soluble in an alkaline solution. This reduction process is the heart of vat dyeing. Traditional methods often involved fermentation vats, but modern techniques rely on reducing agents like sodium hydrosulfite or fructose with calcium hydroxide, which we, as a leading vat dye indigo manufacturer, can advise on for optimal results.


Once the indigo powder is reduced and dissolved into a yellow-green solution, the fiber (be it cotton, linen, silk, or wool) is submerged. The magic unfolds upon removal: as the fabric is exposed to oxygen in the air, the leuco-indigo quickly oxidizes back into its brilliant blue, insoluble form, permanently bonding with the fibers. Repeated dipping and oxidation cycles allow for the build-up of color, creating a vast spectrum of blues, from the palest sky to the deepest navy. Our indigo dyeing techniques allow for precise control over the final shade.
