vat dyeing

Vat dyeing is a textile coloring process where dyes, like indigo, are made water-soluble through chemical reduction. The fabric is immersed in this dye solution, allowing the fibers to absorb the dye. When exposed to air, the dye oxidizes back to its insoluble form, creating vibrant and durable color. This method is often used for denim and other sturdy fabrics because the dye penetrates deeply and is resistant to fading and washing. It’s a controlled process that ensures consistent, long-lasting coloration while allowing the fabric to be softened and finished afterward.
