Abstract:
A dryer dry cleaning and freshening system is provided with a containment bag, a dispenser means impregnated with liquid cleaning composition, and a absorber capable of absorbing loose particles and excess cleaning composition A process for cleaning a garment is also provided. The system and process may be used in a home clothes dryer for dry cleaning.
Abstract:
A containment bag 1 which may be used in home dry cleaning is made of textile with an impermeable finish and an interior capable of absorbing loose particles and soil. The containment bag 1 is used in a home dryer dry cleaning and freshening system. The textile of the containment bag 1 has a layer of woven or knit fabric with an impermeable coating and a soft, hairy layer on its interior. The inside of the containment bag 1 is prewetted with cleaning composition. Preferably a liquid cleaning composition is employed and the cleaning composition may include a fragrance composition. A process for cleaning a garment is also provided.
Abstract:
The separation of a contaminant from a substrate that carries the contaminant is disclosed. The process comprises contacting the substrate to a carbon dioxide fluid containing an amphiphilic species so that the contaminant associates with the amphiphilic species and becomes entrained in the carbon dioxide fluid. The substrate is then separated from the carbon dioxide fluid, and then the contaminant is separated from the carbon dioxide fluid.
Abstract:
A home dry cleaning process is provided. Thus, a carrier sheet releasably impregnated with solvents such as butoxy propoxy propanol, 1,2-octanediol as a wetting agent, water and an emulsifier is placed in a plastic bag with soiled garments and tumbled in a hot-air clothes dryer. The garments are cleaned and refreshed.
Abstract:
A process for the treatment of products constituted by hides and skins with a view towards their transformation into leather, and for the treatment of leather which involves contacting the product with a dense, pressurized fluid, such as CO.sub.2, in the supercritical state or pressurized liquid, which optionally contains one or more active substances and a specified pressure Pi and temperature Ti, in order to provide degreasing of the skins if pure dense fluid is used, or to impregnate the products with active substances such as tanning, stiffening, dyeing or waterproofing agents. The products are subsesquently brought to atmospheric pressure to eliminate the dense fluid therefrom.
Abstract:
A densified fluid barrier cleaning system is disclosed in which a pressure vessel encases a movable basket positioned so as to cross a barrier such that one opening of the pressure vessel resides in a first environment and a second opening of the pressure vessel resides in a second environment. A tubular basket within the pressure vessel is positioned such that its central longitudinal axis is aligned with both the first and second opening of the pressure vessel. Responsive to the successful completion of a cleaning cycle, soiled articles that are introduced to the basket via the first opening from the first environment can be removed through the second opening and into the second environment thus bridging the barrier without fear of introducing contaminants from the first environment to second environment.
Abstract:
Ways to generate softened loofah embedded products are described. Such softened loofah is softened using a softening solution that includes papaya extract, liquid detergent, and water. The softening solution is heated during treatment of the loofah. The softened loofah is pre-rinsed with a solution of bleach and water and/or rinsed with water. The softened loofah is able to be embedded into a cleaning agent such as soap.
Abstract:
The invention provides a method and formulation for cleaning a soiled substrate, the method comprising the treatment of the moistened substrate with a formulation comprising a multiplicity of polymeric particles, wherein the formulation is free of organic solvents. Preferably, the substrate is wetted so as to achieve a substrate to water ratio of between 1:0.1 to 1:5 w/w. Optionally, the formulation additionally comprises at least one cleaning material and, in this embodiment, it is preferred that the polymeric particles are coated with the at least one cleaning material. Preferably, the cleaning material comprises a surfactant, which most preferably has detergent properties. Most preferably, the substrate comprises a textile fiber. Typically, the polymeric particles comprise particles of nylon, most preferably in the form of nylon chips. The results obtained are very much in line with those observed when carrying out conventional dry cleaning processes and the method provides the significant advantage that the use of solvents, with all the attendant drawbacks in terms of cost and environmental considerations, can be avoided.
