Abstract
Dye baths including an aqueous solution including lignin in a range of 10% to 30% by weight of the aqueous solution. In addition, methods of dyeing fibers, yarns, textiles, or garments with an aqueous solution including 10% to 30% lignin by weight is disclosed. Further, methods of dyeing a fabric including preparing a first dye bath including an aqueous solution having lignin in a range of 10% to 30% by weight of the aqueous solution and passing a fabric through the first dye bath such that the fabric pics up lignin to dye the fabric is disclosed.

A method of dyeing fabric, the method comprising:
- preparing a first dye bath comprising an aqueous solution having lignin in a range of 10% to 30% by weight of the aqueous solution;
- and
- passing a fabric through the first dye bath such that the fabric picks up lignin to dye the fabric.
A dye bath comprising:
- an aqueous solution comprising lignin in a range of 10% to 30% by weight of the aqueous solution.
A dye bath comprising:
- an aqueous solution comprising:
- lignin in a range of 10% to 30% by weight;
- and
- binders up to 10% by weight, and
- wherein the aqueous solution is configured to dye cellulosic fibers for use in textiles.
