  • Patent number: 5942008
    Abstract: The present invention relates to a method for dyeing wood veneer. The veneer is immersed in a dye bath. The dye is preferably heated to speed up penetration times. The dye bath containing the veneer is then put into pressurized chamber and pressurized to 50-500 psi. The chamber is pressurized until the wood absorbs the amount of color that is desired. When the color is absorbed the pressure is released and the veneer is removed. The veneer is then washed with water until there is no bleeding and then air dried.

  • Patent number: 4778477
    Abstract: This invention relates to the application of a treatment agent to an air permeable substrate by forming a foam of a liquid containing or constituting the treatment agent and applying the foam to the substrate and causing or allowing the foam to transit the substrate and to be removed from the other side thereof in which process the foam is applied in an excess defined as a ratio of the foam transit liquid content of the material in which case the amount of treatment agent taken up by the substrate will be dependent solely on the concentration of the agent within the foam and not by the volume of the foam applied and further the amount of agent taken up by the substrate is substantially independent of the initial water or liquid content of the substrate.

  • Patent number: 4756633
    Abstract: An improved inking ribbon for color transfer under the influence of heat comprises the ribbon having a carrier layer and a colored layer with the heat-soluble release layer interposed therebetween, which release layer is composed of a sublimable material to avoid renewed adhesion of the released portion of the color layer to the inking ribbon after a color transfer to the printing medium has occured.

  • Patent number: 4365968
    Abstract: Disclosed herein is a process for treating textile materials with finishing agents wherein a first finishing agent-containing composition is applied to a textile material and a second composition, in the form of a foam, is thereafter applied to the textile prior to fixation of the the first applied composition. The first composition may also be applied in the form of a foam if desired. The compositions may also contain reactive materials therein.

  • Patent number: 4299591
    Abstract: Disclosed herein is a process for printing on textile materials, particularly pile type fabrics, wherein a foamed printing composition is first applied to the textile material; a second foamed composition is thereafter uniformly applied onto the textile over the printing composition prior to fixation of the latter; the second applied foam is then collapsed to form a pre-selected print on the textile; and the printed textile is then subjected to color fixation.
