  • Patent number: 6139590
    Abstract: A dyeing and printing system for use in color printing articles or fabrics formed from cellulose prior to dyeing. In the preferred embodiment, the dyeing system composition includes the selective use of a dye blocking print paste, a color binder print paste and a dye enhancing print paste to selectively decrease or increase the shade of the dyed portions of a cellulose article, such as a woven or knitted cotton or cotton/polyester article or fabric while, at the same time, permitting the resisted areas to be colored differently.

  • Patent number: 5908775
    Abstract: The invention provides a method of textile printing using microorganisms with less limitation to dyes with less damage on base materials, and with less blurring of color borders. The method is capable of producing a complex, fine pattern; capable of realizing colored discharge printing with brilliant colors; and capable of readily producing an ombre pattern. The invention also provides a microorganism for decolorization of azo-system dye and use in the textile printing method. In accordance with the invention, textile printing is carried out by coating a solution or paste (which may contain a dye) containing a bacterial strain Bacillus OY1-2 of genus Bacillus (Deposit Number: FERM 13118), in a desirable pattern on the cloth dyed with an azo dye (which may include a non-azo dye), subsequently proliferating or acting the bacterial strain while keeping the strain in a wet state, and to entirely or partially metabolize the azo dye to eliminate or decrease the coloring of the azo dye for textile printing.

  • Patent number: 4222740
    Abstract: A coloration method for textiles using chemically formed gels is disclosed. The method provides considerable freedom for making color designs and precise pattern prints, and can be used with conventional dyeing and printing equipment. In one embodiment of this invention, gelled regions are formed by separately applying a gelable composition containing alginic acid or an alginic acid derivative and a gelling agent composition to a textile material, and then over-dyeing the material, the gelled regions serving as dye resist regions.
