Claims25
A bag adapted for containment and cleaning of a soiled fabric article, said bag comprising (a) an opening comprising a fastening system so that the bag can enclose in a vapor impermeable manner a soiled fabric article and (b) at least a portion of the interior surface having an effective amount of a dry-cleaning composition releasably absorbed thereto, wherein the dry-cleaning composition consists essentially of about 40-95% water, about 0.25-8% of a gelling agent, about 2-32% of a water miscible organic solven and about 1-10% surfacant, wherein said bag is formed of a flexible non-porous material which is not substantially damaged upon exposure to agitation and to a temperature effective to cause the release of said dry-cleaning composition from said interior surface.
A process for cleaning a soiled fabric article with a cleaning composition, said process comprising:
- (a) placing said soiled fabric article into a bag, said bag comprising (i) an opening comprising a reversible fastening system so that the bag can enclose said soiled fabric article in a vapor impermeable manner and (ii) an interior surface having an effective amount of a dry-cleaning composition releasably absorbed thereinto, said dry cleaning composition consisting essentially of a liquid vehicle selected from the group consisting of water, a water-miscible organic solvent and mixtures thereof;
- an effective amount of a gelling agent, and about 0.5-5% by weight of surfactant;
- (b) closing said fastening system to form said bag into a closed system comprising said soiled fabric article;
- (c) tumbling said closed system in a rotary clothes dryer at an elevated temperature, so that the dry-cleaning composition is released from said interior surface, and contacts said soiled article so as to effectively disperse said soil;
- and
- (d) opening said fastening system and removing the cleaned fabric article from the bag.
A method for stain removal from a solid fabric article, said method comprising the steps of:
- (a) placing the soiled fabric article into a bag, said bag comprising (i) an opening comprising a reversible fastening system so that the bag can enclose said soiled fabric article in a vapor impermeable manner and (ii) an interior surface having an effective amount of dry-cleaning composition releasably absorbed thereinto, said dry-cleaning composition comprising a liquid vehicle selected from the group consisting of water, a water-miscible organic solvent and mixtures thereof;
- about 0.25-5% by weight of a gelling agent;
- and an effective soil-dispersing amount of a surfactant, said bag being formed of a non-porous material which is not substantially damaged upon exposure to agitation and to a temperature effective to cause the release of said composition from said interior surface;
- (b) sealing the opening;
- and
- (c) tumbling the sealed bag for a sufficient time and at a sufficient temperature to release the dry-cleaning composition from the interior surface and to contact an effective amount of the released dry-cleaning composition with the soiled fabric article, so as to clean said soiled fabric article.
