Abstract
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.
