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.

Casings, dye tablets, DIY activity-kits include one or more casings, one or more encased dye tablets, or a combination thereof, that are configured to impart an artistic effect to an article, hydrographic sheets, and dip and decorator activity-kits including one or more hydrographic sheets and an instruction for imparting an artistic effect to the article using the one or more hydrographic sheets. The casings include at least one compartment formed of a water-soluble film, and one or more agents disposed within the at least one compartment. The encased dye tablet includes one or more agents compounded with a filler and a binder. The one or more agents include at least one colorant formulation and at least one fixative.

The application of melanin to fabric improves resistance to chemical pass-through, with possible application in protective garments, shelters, and filtration materials.

Methods for obtaining natural colorants from plant material (e.g., tobacco material) and for using such natural colorants to dye various substrates are provided. Natural colorants are obtained using particular enzymes and particular conditions (e.g., time, temperature, and pH profiles). Such colorants can be used to dye substrates, for example, using conventional dyeing techniques or using unique in situ methods.

Hydrographic sheets and dip and decorator activity-kits are provided. The dip and decorator activity-kits comprise one or more hydrographic sheet formed of a water-soluble film, having decoration art formed from a non-aqueous ink or dye disposed on at least one side of the sheet, and an instruction for imparting an artistic effect to the article using the one or more hydrographic sheets. The hydrographic sheet leaves floating decoration art upon dissolution in water and wherein the floating decoration art comprises a softened and at least partially solubilized water-soluble film with decoration art for adhering to an article.

The present disclosure provides methods for making synthetic hair compositions. The methods generally comprise providing a plant fiber, degumming the plant fiber, and dyeing the plant fiber. The present disclosure also provides methods of degumming banana fiber. The methods generally comprise providing banana fiber and soaking the banana fiber in a degumming solution comprising a base, magnesium sulfate, and hydrogen peroxide. The present disclosure further provides methods of dyeing banana fibers. The present disclosure further provides synthetic hair compositions comprising banana fibers made by the methods described herein.

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.
