For centuries, natural dyeing has captivated artisans with its ability to transform fabrics using pigments derived from plants and minerals. A key secret to achieving vibrant, lasting colors in this ancient craft lies in the use of mordants. Among these, Tannic Acid stands out as an indispensable textile mordant, particularly when working with cellulose fibers like cotton and linen.

Tannic Acid (CAS 1401-55-4), a specific form of tannin extracted from plants, acts as a bridge between the natural dye and the fabric fibers. Without a mordant, many natural dyes would simply wash out over time, leading to disappointing results. Tannic Acid creates a chemical bond, allowing the dye molecules to adhere firmly, thus dramatically improving the lightfastness and washfastness of the dyed material. This is why when you want to buy high quality tannic acid powder, NINGBO INNO PHARMCHEM CO.,LTD. is your trusted supplier.

Its use is especially critical for cellulose fibers because, unlike protein fibers (wool, silk), cellulose doesn't naturally bond as readily with metallic mordants like alum or iron. Applying Tannic Acid first, often in conjunction with other mordants, prepares the fiber to accept and retain the dye more effectively, leading to deeper, richer hues and more durable colors.

Beyond its primary role as a mordant, Tannic Acid also contributes to the final color palette. When combined with iron, for instance, it can produce beautiful shades of grey and black, offering natural dyers an expanded range of creative possibilities. This makes tannic acid for textile dyeing mordant an invaluable tool for artisans and industrial textile producers alike.
