Abstract:
The present invention relates to stain removal methods and products associated therewith. The methods of the present invention are especially useful as part of a dry cleaning operation, but can also be used under any circumstances where stain removal from articles, especially fabrics, is desired.
Abstract:
A fabric treatment article for use in a conventional home clothes dryer is described that deodorizes and freshens clothing in need of freshening without imparting additional stains. The product is particularly suited for delivering a fragrance to relatively dry clothing and can be added directly to the dryer without the need for a bag to contain the product and clothing during the dryer cycle.
Abstract:
Soil removal methods, especially non-immersive soil removal methods, and devices employed in such methods for removing and/or reducing soil present on leather articles are provided.
Abstract:
This invention relates to new compositions and methods for cleaning textile substrates, especially carpet and upholstery fabrics. More particularly, this invention relates to liquid compositions that contain absorbent particles in a flowable fluid dispersion, which dries to a soil ladened powder, that can be removed by vacuuming, brushing, and/or laundering methods. The composition includes dispersion stabilizing additives such that the composition is presented as a stable dispersion or as a composition that may be easily redispersed prior to application.
Abstract:
The present invention relates to methods to treat fabrics with lipophilic fluid, a polar phase and bleach system. The present invention is also directed to compositions containing lipophilic fluid, a polar phase and a bleach system.
Abstract:
A system for dry cleaning soils from fabrics comprising densified carbon dioxide and a surfactant in the densified CO2. The densified carbon dioxide is in a temperature range of about −78.5° C. to about 100° C. and a pressure range of about 14.7 to about 10,000 psi. At least 0.1% by volume of a modifier is preferably present. The surfactant has a polysiloxane a branched polyalkylene oxide or a halocarbon group which is a functional CO2-philic moiety connected to a CO2-phobic functional moiety. The surfantant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.
Abstract:
A system for the softening or other treatment of fabric articles is provided which comprises a vented bag comprising a fastening system and flexible sheet releasably impregnated with an effective amount of a liquid fabric-treatment composition.
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 liquid composition useful for suspending and dispensing a solid particulate comprises carbon dioxide, a surfactant, an organic co-solvent, and the solid particulate to be suspended. The composition may optionally contain water. The composition is useful as a propellant in an aerosol container for spraying the solid particulate from the container.
Abstract:
A method for dry-cleaning articles such as fabrics and clothing in carbon dioxide comprises contacting an article to be cleaned with a liquid dry cleaning composition for a time sufficient to clean the fabric. The liquid dry-cleaning composition comprises a mixture of carbon dioxide, a surfactant, and an organic co-solvent. After the contacting step, the article is separated from the liquid dry cleaning composition. The method is preferably carried out at ambient temperature. The surfactant is preferably one that does not contain a CO2-philic group. The organic co-solvent is preferably an alkane and has a flash point above 140° F.
