Chemically Modified Local Areas Patents (Class 8/458)
  • Patent number: 9797090
    Abstract: A photocatalytic method of colored discharge printing for producing colorized patterns on textiles includes over dyeing textiles with illuminant dyes and ground shade dyes respectively, manufacturing patterned printing plates with hollow-out decorative patterns, applying a photocatalyst on the over-dyed textiles through the hollow-outs, using a photocatalytic method of colored discharge printing to produce localized discoloration of the ground shade while leaving the illuminant dyes on the textile which produces an effect of colorized patterns on the textiles. The method has the characteristics of being a simple process with a simple apparatus and has short processing, easy control and wide adaptability. The method eliminates the needs for printing pastes and expensive printing apparatus used in the complicated process in a conventional printing method.

  • Patent number: 8092554
    Abstract: The discharge print paste formulation contains synthetic layered silicate as a carrier and thickening agent, one or more bleaching agents selected from sodium hypochlorite and hydrogen peroxide, water and optionally sodium hydroxide and discharges color when applied to washable color fast natural fabric (cotton, linen) or washable synthetic and permanent press fabric. The discharge print paste formulation is applied to the fabric. The treated fabric is dried at room temperature, washed and dried to get a pattern of discharged color where the discharge print paste formulation is applied.

  • Patent number: 7670387
    Abstract: The invention relates to a synthetic fiber fabric having translucent printing (dyeing) patterns thereon. The invention also relates to a process for producing a synthetic fiber fabric having translucent printing (dyeing) patterns thereon, which includes a printing step prior to an etching step, wherein the printing step includes printing a paste for dyeing and/or printing containing a transparent printing developer onto a surface of the fabric.

  • 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: 5593458
    Abstract: A processing composition for decorating a dyed cloth fabric. The composition is a dye reactive oxidizer carrying gel and the method of use is to silkscreen onto the fabric to be decorated with the oxidizing gel. The gel is allowed to react with the dye of the fabric in a pattern dictated by the silkscreening pattern. The oxidizing agent is then removed from the fabric.

  • Patent number: 5131915
    Abstract: A pattern or design is formed on an already dyed cellulose-containing fabric by wetting preselected portions of the fabric with a solution containing a bleaching agent, drying the wetted fabric by heating at about 100.degree. C., and washing the dried fabric free of residual chemicals.

  • Patent number: 5022891
    Abstract: The process for producing patterns on ground dye colored textile fiber pile substrates, particularly wherein the pile fibers are in the form of yarns comprised predominantly of polyamide fiber, and wherein at least some of the ground dye component is at least partially color dischargeable and selected from vat, reactive, direct, acid, premetallized or mordant dyes, the process comprising contacting selected portions of the colored pile fibers with a reducing system which optionally can contain one or more reduction resistant dye or pigment materials for in situ coloring of the substrates, the contacting being characterized by jet forcing the reducing system interstitially of the pile fibers to deposit the reducing system thereon substantially below the surface thereof, and to effect the color discharge of at least a portion of the ground dye component.
