  • Patent number: 7795200
    Abstract: This invention includes a cleaning composition, the method of use of the cleaning composition, and a new use of a composition. The composition includes an oxidizing agent with a reduction potential of greater than about 0.1 E°(V) at 25° C., and is devoid of an oxidizing agent with a reduction potential of greater than about 1.5 E°(V) at 25° C. The oxidizing agent may be a salt of a nitrate or nitrite. The method includes applying the composition to a textile and working the composition. The composition may be effective in cleaning urine odors from textiles. The composition may remove odors from textiles without bleaching or discoloring the textile, even if the textile includes natural fibers such as wool.

  • Patent number: 7503940
    Abstract: Methods for spot-dyeing a damaged area on a textile employing a selected color loss filter and utilizing at least one of a primary color dye. In one embodiment, the method can include the following: inspecting the damaged area through the selected color loss filter; determining whether a primary color is missing from the damaged area by being able to view the damaged area through the selected color loss filter to, thereby, confirm that the primary color is missing from the damaged area; and applying at least one of a primary color dye, corresponding to the selected color loss filter, to the damaged area, while viewing the damaged area through the color loss filter, until the damaged area is substantially invisible through the color loss filter.

  • Patent number: 7404224
    Abstract: A stain removing composition having a mixture of N-methyl pyrrolidinone and at least one solvent from the group consisting of 3-pentanol, dipropylene glycol monomethyl ether, propylene glycol n-propyl ether, and diethylene glycol monobutyl ether. Preferably the stain removing composition comprises, in percent by weight about 70-90%, N-methyl pyrrolidinone and about 10-30%, in percent by weight, at least one of the solvents from the group described above. In another embodiment, a method of removing a stain from a textile includes the steps of applying the stain removing composition to an area of application. After the composition has been applied to the area of application it is removed with a suction device or other type of absorption device. Water may be applied to the area of application after the composition has been applied to dilute the composition and help in the removal process.

  • Patent number: 7059541
    Abstract: A fluid mixing arrangement, referred to as a mixing block, for use in mixing two liquids like an acidic and a basic components of a cleaning solution, which is placed under pressure and sprayed through a conventional spray gun or nozzle at a reduced amount of pressure. In particular, the innovative design of the present invention provides the unique features of allowing manual and visual inspection of the various chambers, inlets, flow-rate or pressure reducing orifices, supply filters, and backflow preventing valves of the mixing block.

  • Patent number: 6981338
    Abstract: A device for enhancing removal of liquid from fabric, such as a vacuum head device for removing liquid from carpet, includes a first and second surface forming an extraction slot. The first surface may include a plurality of channels extending towards the extraction slot configured to direct the liquid toward the extraction slot. Alternatively, the first surface may have a smaller surface area and the second surface may be configured with a lower surface in order to penetrate the carpet and act as a squeegee. The cross-sections of the first and second surfaces are preferably circular. In another embodiment, the cross-sections of the first and second surfaces may comprise, but are not limited to, a semi-rectangular cross section, a V-shaped cross-section, or an elliptical cross-section.

  • Patent number: 6905553
    Abstract: The present invention involves a solvent vapor transfer device for holding an absorbent pad, which receives and disperses solvent vapors over a lacquer-based residue on a textile. A solvent is poured or dripped into an absorbent pad portion of the vapor transfer box, from which solvent vapors are released. The solvent vapors pass through the vapor transfer box and concentrate in a vapor chamber over the lacquer-based residue and textile. As the solvent vapors come into continuous contact with the lacquer-based residue, the residue begins to dissolve and soften. Upon sufficient dissolution, minute quantities of the liquid solvent may be applied directly to the partially dissolved residue and quickly suctioned into an extraction vacuum. This process may be repeated as necessary to achieve complete removal of the residue.

  • Publication number: 20040177452
    Abstract: Three separate color loss filters are used to aid an applicator's ability to accurately match a textile color. These filters include a blue loss filter, a red loss filter, and a yellow loss filter which only allow a narrow band of light wavelengths to pass through. Working dye solutions are prepared according to the shade of the textile or they may be more accurately prepared according to a comparator gray scale card, which is used to determine the contrast between a white sample and an undamaged area of the textile to be dyed. While inspecting the damaged area through the blue loss filter, any visible spots indicate a blue color loss in the damaged area. The applicator applies a previously prepared working blue dye to a damaged area repeatedly, while looking through the blue loss filter, until the damaged area is invisible. The excess dye is vacuum extracted. The same process is repeated for red and yellow dyes, utilizing their respective color loss filters, until a near perfect color match is achieved.

  • Publication number: 20040118439
    Abstract: A vehicle mounted low amount of solution textile cleaning system. Uniquely, the present invention provides for a truck mountable textile cleaning system that: 1) uses less water than the typical existing truck mounted cleaning systems to clean the same amount of area; 2) requires a smaller amount of environmentally damaging water-based cleaning solutions so that fewer trips to dump sites are needed for the same amount of cleaning; and 3) has a self contained water-based cleaning solution that does not have to be connected to a customers expensive water supply during operation. The invention may provide a vehicle that is adapted to implement application of a cleaning solution to a remote textile area to be cleaned. Specifically, the vehicle may comprise a storage system, positioned in the vehicle, and designed to hold the cleaning solution. Additionally, there may be a delivery system fluidly coupled to the storage system to enable delivery of the cleaning solution to the textile area to be cleaned.
