VAT BROWN

VAT Brown
Product Description
VAT Brown is a synthetic vat dye known for its rich, deep brown coloration and excellent durability on cellulose fibers such as cotton, rayon, and linen. It is widely used in textile applications requiring superior fastness properties including resistance to washing, light, and rubbing. The dyeing process involves a reduction-oxidation mechanism that allows the dye to penetrate fibers deeply, resulting in vibrant and long-lasting brown shades. VAT Brown is also employed in specialty applications requiring stable and durable brown pigmentation.

Uses
Primary Uses

• Dyeing cellulose fibers such as cotton, rayon, and linen to produce deep brown colors.
