Disclosed is an environmentally friendly method that enables the pre-treatment and dyeing processes applied to cellulosic products used in the production of textile products such as towels, bathrobes to be carried out in a single bath with natural, biological preparations.

The present disclosure relates to a natural dyeing method using fermented persimmon juice, and more particularly to a natural dyeing method using fermented persimmon juice, which prevents the discoloration of a naturally dyed fabric, is harmless to the human body, and exhibits excellent color development, excellent antibacterial activity, excellent deodorization, and excellent dyeing fastness such as friction fastness and light fastness.

This invention relates to a method for dyeing fabrics, yarns and fibers using microorganisms whereby the adsorption of dye-containing microorganisms onto textile fibers is improved using carbon sources above a threshold concentration. Dye molecules contained within the microorganism are released from the microorganism and fixed directly and locally to the textile fibers using a heat treatment step. Said heat treatment also deactivates the carrier microorganisms. Single or multiple microorganism species, and single or multiple dyes produced by said single or multiple microorganism species may create a variety of textile colors. Suitable synthetic dyes may also be added before, during or after microorganisms have produced dyes but before the dye-releasing heat treatment step.

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.
