  • Patent number: 11333465
    Abstract: A camouflage cover that is simple to deploy and store and is robust to all weather conditions and storage cycles provides a close visual match and close visible and IR spectral signature matches to surrounding vegetation. The cover incorporates a mixture of SAP and cellulose pulp containing approximately 90% water laminated between opaque, non-woven Tencel™ layers to emulate the spectral signature of leaves. Outer polymer film layers prevent water evaporation of the SAP. Organic dye-printed patterns can be applied to one or more of the Tencel™ and film layers. The SAP mixture can be limited to leaf regions of the cover, whereby branch regions include cellulose but not SAP. The cover can be petalized by cuts made, for example, along leaf and branch region boundaries. A gloss-controlling aerogel coating can be applied to outer surfaces of the camouflage cover to match a gloss of the vegetation.

  • Patent number: 6533824
    Abstract: A new method for spot dying nylon carpet requires no color theory nor use of a color wheel. The new method is distinguished from prior art methods primarily by the fact that the focus in on the hue of the spot at any given moment during the process, and that primary dye colors are applied in a sequence determined by the color of the spot. The method has been shown to work on both solid-color and multi-color nylon carpets. It is also effective for spot dyeing light-color (off-white) carpets. The method can also be employed to repair stained areas of a carpet by simply bleaching the stained area and redyeing the bleached area. Prior to the redyeing process, the area to be treated is subjected to several rinse and extract steps. A bleach neutralizer is then applied, allowed to remain on the area to be treated for about 5 minutes, then extracted without further rinsing.

  • Patent number: 6494925
    Abstract: The present invention provides a sculptured pile fabric having both a printed pattern and a sculpted surface of various pile heights. The fabric of the present invention has improved aesthetic qualities as compared with sculptured products of the prior art. This improved sculptured fabric is the result of a chemical sculpting method, in which the height of the pile surface is selectively reduced in a pattern configuration, and that is followed by an overall “dilute” dyeing process. This “dilute” dyeing process is similar to that used to “tea stain” textile products, wherein an overall hue is imparted to a textile by the use of a relatively dilute (low concentration) dyestuff. The resulting sculptured product has an appearance that emphasizes the sculptured areas, making the sculptured areas appear to have greater depth, especially when viewed at a distance.

  • Patent number: 6136044
    Abstract: Micro-particles of transition metals or their compounds can be generated as an integral part of a fiber by first attaching a nucleating agent to the fiber, and then adding a solution of metal ions. The ions are reduced by the nucleating agent in the fiber, and micro-particles are generated in or on the fiber. Because of the strong color signal resulting from a low concentration of metal micro-particles, the method is cost effective even when using gold or titanium ions. Various colors were generated by changing the size and spacing of the micro-particles, the metal or metal complex used, and the characteristics of the fiber. The dyed fibers displayed colors ranging from pink, red, purple, yellow, orange, peach, brown, gold, silver, grey, green, and black. These colors resisted bleaching by either chemicals or light.

  • Patent number: 6136043
    Abstract: The present invention is directed to polishing pads useful in determining an end to the useful wear life thereof. In a simple embodiment of the present invention, a polishing pad that is used with slurries is dyed on one side in a manner that causes the dye to permeate the pad to a limited depth that does not cause total coloring. Another embodiment of the present invention involves a fixed abrasive pad that has fixed abrasives embedded into the pad to a selected depth where at least one color level is within the portion of the pad that contains the fixed abrasives. After dyeing the pad, the pad is attached to the polishing platen. During the polishing operation, a color change signals a time to stop the polishing operation and change the pad. With multiple colors in the pad, limited only by the ability to dye the pad with uniform depth levels, characteristic wear patterns can be observed and adjustments made accordingly to prolong and optimize pad life.

    Abstract: A method and apparatus for pattern dyeing of textile substrates in which the dyeing is done in two stages. In the first stage, a dye is uniformly applied in a manner that allows the dye to fix on contact. The uniformly dyed substrate is then moved under a series of spaced arrays, each array being associated with a separate color and being comprised of a plurality of individually controlled liquid dye applicators. Liquid dye of a given color is selectively applied through one or more dye applicators as the substrate passes under the array associated with that color. The applied dye remains unfixed until the substrate passes under all the arrays and the patterning is complete, whereupon all dye applied by the dye applicators is fixed by steaming or other appropriate application of energy to the substrate.

The textile fabric is then rewetted by the application of liquid. The printed areas containing liquid repellant remain dry and the areas without liquid repellent are selectively wetted out. The textile fabric is then subjected to pressurized heated gas which selectively carves the dry areas printed with liquid repellent leaving the wetted areas protected and uncarved. As an alternative embodiment, the yarns that make up a textile fabric can be individually treated with a liquid repellent prior to being formed into a textile fabric.

  • Patent number: 5447539
    Abstract: A method of dyeing polypropylene fiber to create areas of different color on the fiber. A first dye solution containing a disperse dye and a dye-promoting agent is applied to substantially the entire surface of the fiber to cover the fiber with a first color. Thereafter, and while the fiber surface is still wet with the first dye solution, a second dye solution containing a disperse dye of a second color is applied only to selected discontinuous areas of the fiber. The second dye solution displaces the first dye solution in those areas of the fiber surface to which the second dye solution is applied. Then, the fiber is subjected to an elevated temperature high enough, and for a period of time sufficient, to fix the dyes in the fiber. Preferably, the second dye solution is more viscous than the first dye solution. After the dye fixation step, the fiber is scoured to remove excess dye. If desired, the second dye solution also contains a dye-promoting agent.

  • Patent number: 5400257
    Abstract: A method for producing a Batik-type image on cloth. Artwork is generated manually or via a computer graphic art program, which contains an outline of a Batik-type image to be produced on cloth. The outline simulates wax drip lines. Coloration is then added to selected areas, and the artwork is color separated into individual images. Simulated wax crack lines are then added to the color separations. Screens for each individual color are produced, and the cloth is printed using a discharge type ink. The result is an image very similar to Batik style dyeing.

  • Patent number: 5066512
    Abstract: Methods for the coating of different closely-spaced areas of an electrode member to produce a color filter matrix thereon. A thin translucent layer of electroconductive composition, such as indium tin oxide (ITO), is applied to isolated areas of the electrode substrate, and selected ones of said areas are charged to one polarity while the other closely-spaced areas are charged to an opposite polarity. Color material is introduced as fine droplets in a volatile vehicle, charged to said opposite polarity, for selective attraction to said selected areas and repulsion from all other areas. The procedure is repeated with different color material droplets for deposition on others of said closely-spaced areas to produce a multi-colored matrix filter, such as on the lower pel electrode or on the upper pixel common electrode of a LCD device. Preferably the ITO layer is coated with a thin polymer layer and the color material is a diffusible dye which is heat-diffused thereinto.
