Abstract
A method for cleaning soiled fabric articles is provided which comprises tumbling the soiled articles in a rotary clothes dryer at an elevated temperature, in a closed system, such as a sealed plastic bag, wherein said system also includes a fabric-cleaning article comprising a porous substrate sheet impregnated with a gelled liquid cleaning composition.
Claims31
A fabric-cleaning article comprising a porous substrate sheet stably impregnated with a gelled cleaning composition consisting essentially of about 40-95% water, about 0.25-5% of a gelling agent, about 2-32% of a water-miscible organic solvent and about 5-10% surfactant.
A fabric-cleaning kit comprising, packaged in association,
- (a) at least one plastic bag having an opening comprising a fastening system so that the bag can enclose in a vapor-impermeable manner, a soiled fabric, and
- (b) at least one fabric-cleaning article comprising a porous substrate sheet stably impregnated with a gelled cleaning composition comprising about 40-95% water, about 0.25-5% of a gelling agent, about 2-32% of a water-miscible organic solvent and about 0.5-10% surfactant, wherein said cleaning article is separately packaged in a moisture-impermeable envelope.
A process for cleaning a soiled fabric article with a cleaning composition, said process comprising:
- (a) placing said soiled fabric article and a fabric-cleaning article comprising a porous substrate sheet stably impregnated with a gelled cleaning composition comprising about 40-95% water, about 0.25-5% of a gelling agent, about 2-32% of a water-miscible organic solvent and about 0.5-10% surfactant, into a plastic bag;
- (b) forming said bag into a closed system comprising said soiled fabric article and said fabric-cleaning article;
- (c) tumbling said closed system in a rotary clothes dryer at an elevated temperature, to enable the gelled cleaning composition to contact said soiled article and to disperse said soil;
- and
- (d) removing the cleaned fabric article from the closed system.
(c) tumbling said closed system in a rotary clothes dryer at an elevated temperature sufficient to dispense the gelled cleaning composition without substantially damaging the bag to enable the gelled cleaning composition to contact said soiled article and to disperse said soil;
- and
A composite fabric-cleaning article comprising a flexible porous base sheet, having coated thereon an effective amount of a gelled cleaning composition comprising:
- (a) about 60-90% of water;
- (b) about 0.25-5% of a gelling agent;
- (c) about 5-25% of an organic solvent;
- and
- (d) about 0.5-10% of a surfactant;
- and wherein said composition, when released from said sheet, provides for soil removal from a soiled fabric article when said sheet is applied thereto under conditions of pressure.
A fabric-cleaning kit comprising:
- (a) a composite cleaning article comprising a non-woven fabric sheet having coated thereon an effective amount of a gelled cleaning composition comprising:
- (i) about 40-95% water;
- (ii) about 2-32% of a water-miscible organic solvent;
- (iii) about 0.25-5% of a gelling agent;
- and (iv) about 0.5-10% of a surfactant;
- wherein said composition, when released from said sheet, provides for stain removal from a stained fabric article;
- and
- (b) a separately provided bag adapted for containment of said cleaning article and a soiled article of clothing, wherein said bag comprises 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 sheet.
A method for stain removal from a soiled fabric article, said method comprising the steps of:
- (a) placing the soiled fabric article and a composite cleaning article comprising a non-woven fabric sheet having coated thereon a composition comprising about 40-95% water, about 2-32% of a water-miscible organic solvent, about 0.25-5% of a gelling agent, and about 0.5-10% of a surfactant within a bag 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 sheet;
- (b) sealing the bag;
- and
- (c) tumbling the sealed bag for a sufficient time and at a sufficient temperature to contact an effective amount of the released cleaning composition with the stained fabric article, so as to clean said fabric article.
