Abstract
A process for the removal of stains from fabrics, such as carpets. The process comprises treating the stained areas of the fabrics with a liquid, paste-form or foam-form stain remover and subjecting the entire fabric to cleaning with a powder-form cleaning composition before the treated areas have dried. The preferred stain remover is an aqueous composition containing a surfactant, and the preferred powder-form cleaning composition contains a finely divided cellulose powder as an adsorbent. The new process is suitable above all for the cleaning of carpets and carpeted floors.
Claims15
A process for the removal of stains from fabrics in which the stain is first treated with a liquid, paste-form or foam-form stain remover composition, after which the entire fabric is treated with a powder-form cleaning composition before the stain remover composition has dried.
A process for removal of stains from fabrics comprising:
- (a) rubbing the stained area of the fabric with an aqueous stain remover composition containing an effective amount of a surfactant, said stain remover composition being applied at a level of about 0.2 to about 30 grams per square decimeter of stained surface;
- (b) applying to the surface of the fabric a powder-form cleaning composition having the following composition:
- about 35 to 70% by weight of cellulose powder having a particle size of 1 to 150 micrometers,
- about 25 to 60% by weight of water,
- about 5 to 22% by weight of an organic solvent,
- about 0 to 4% by weight of a surfactant from the group consisting of anionic surfactants, nonionic surfactants and mixtures thereof, and
- about 0 to 5% by weight of other dry cleaning composition additives,
- said powder-form cleaning composition being applied at a level of about 20 to about 200 grams per square meter of fabric surface;
- (c) brushing the composition of step (b) into the fabric for a period of time ranging from about 0.5 to about 2.5 minutes per square meter of fabric surface;
- (d) permitting the fabric to dry;
- and
- (e) mechanically removing the composition from the fabric,
- said process further characterized in that steps (b) and (c) are carried out prior to the drying of said stain remover composition.
