Abstract

A bag for the cleaning and containment of soiled fabric articles is provided which comprises a fastening system that, when fastened provides a vapor impermeable container and an interior surface releasably impregnated with an effective amount of a gelled liquid dry-cleaning composition.

Claims

1. A home dry-cleaning kit comprising:

(a) a gelled or liquid cleaning or freshening composition consisting essentially of a gelling agent present in an amount effective to stabilize the composition and to allow the dispersion of the composition on fabric articles while leaving no significant undesirable visible residue on the fabric articles;

a liquid vehicle selected from the group consisting of water, an organic solvent, and mixtures thereof; and

at least one surfactant; and

(b) at least one bag having an opening comprising a fastening system so that the bag can enclose a fabric article in a vapor-impermeable manner, and an interior surface at least a portion of which is absorptive and is suitable for releasably absorbing the cleaning or freshening composition and for absorbing soil from fabric articles and moisture, wherein the bag is formed of a flexible non-porous material which is not substantially damaged upon exposure to tumbling and heat in a hot rotary dryer.

2. The kit of claim 1, wherein the cleaning or freshening composition is in a spray, a dipping solution or impregnated in a sponge.

3. The kit of claim 1 wherein the cleaning or freshening composition further consists essentially of an inorganic salt.

4. The kit of claim 1 wherein the cleaning or freshening composition consists essentially of about 40-95% by weight of water, about 0.25-8% by weight of a gelling agent, about 2-32% by weight of an organic solvent and about 1-10% by weight of surfactant.

5. The kit of claim 1 wherein the organic solvent consists essentially of at least one glycol ether.

6. The kit of claim 1 wherein the surfactant is a nonionic surfactant.

7. The kit of claim 1 wherein the surfactant is an amphoteric surfactant.

8. The kit of claim 1 wherein the gelling agent is an organic gum.

9. The kit of claim 8 wherein the organic gum is carrageenan.

10. The kit of claim 4 wherein the cleaning or freshening composition further consists essentially of about 0.0025-0.1% by weight of a metal halide salt.

11. The kit of claim 3 wherein the inorganic salt is selected from the group consisting of an alkali metal halide salt and an alkaline earth metal halide salt.

12. The kit of claim 1, wherein the cleaning or freshening composition is applied to the absorptive interior surface of the bag.

13. A process for cleaning or freshening a soiled fabric article with a cleaning or freshening composition, which process comprises:

(a) applying a cleaning or freshening composition onto a soiled fabric article by means of a spray, a dipping solution or a sponge, which cleaning or freshening composition comprises a gelled or liquid cleaning or freshening composition consisting essentially of a gelling agent present in an amount effective to stabilize the composition and to allow the dispersion of the composition on fabric articles while leaving no significant undesirable visible residue on the fabric articles;

a liquid vehicle selected from the group consisting of water, an organic solvent, and mixtures thereof; and

at least one surfactant;

(b) placing the soiled fabric article into a bag having an opening comprising a fastening system so that the bag can enclose the soiled fabric article in an effective vapor impermeable manner, which bag has an interior surface at least a portion of which is absorptive and is suitable for releasably absorbing the cleaning or freshening composition and for absorbing soil from fabric articles and moisture, wherein the bag is formed of a flexible non-porous material which is not substantially damaged upon exposure to tumbling and heat in a hot rotary dryer;

(c) closing the fastening system to form the bag into an effective closed system comprising the soiled fabric article onto which is applied the cleaning or freshening composition;

(d) tumbling the closed system in a rotary clothes dryer at an elevated temperature, so that the cleaning or freshening composition is vaporized from the soiled fabric article so as to effectively disperse the soil and/or freshen the fabric article, and soil and moisture are absorbed by the absorptive interior surface of the bag; and

(e) opening the fastening system and removing the cleaned or freshened fabric article from the bag.

14. The process of claim 13, wherein the cleaning or freshening composition is also applied to the interior surface of the bag.

15. The process of claim 13, wherein the cleaning or freshening composition is applied to the fabric article in step (a) by means of a spray.

16. The process of claim 13 wherein the cleaning or freshening composition further consists essentially of an inorganic salt.

17. The process of claim 13 wherein the cleaning or freshening composition consists essentially of about 40-95% by weight of water, about 0.25-8% by weight of a gelling agent, about 2-32% by weight of an organic solvent and about 1-10% by weight of surfactant.

18. The process of claim 13 wherein the organic solvent consists essentially of at least one glycol ether.

19. The process of claim 13 wherein the surfactant is a nonionic surfactant.

20. The process of claim 13 wherein the surfactant is an amphoteric surfactant.

21. The process of claim 13 wherein the gelling agent is an organic gum.

25. The process of claim 13, wherein in step (a) the cleaning or freshening composition is further applied to the absorptive interior surface of the bag.

26. A process for cleaning or freshening a soiled fabric article with a cleaning or freshening composition, which process comprises:

(a) applying a cleaning or freshening composition onto an absorptive interior surface of a bag by means of a spray, a dipping solution or a sponge, which absorptive interior surface is suitable for releasably absorbing the cleaning or freshening composition and for absorbing soil from fabric articles and moisture,

wherein the cleaning or freshening composition comprises a gelled or liquid cleaning or freshening composition consisting essentially of a gelling agent present in an amount effective to stabilize the composition and to allow the dispersion of the composition on fabric articles while leaving no significant undesirable visible residue on the fabric articles;

a liquid vehicle selected from the group consisting of water, an organic solvent, and mixtures thereof; and

at least one surfactant,

wherein the bag is formed of a flexible non-porous material which is not substantially damaged upon exposure to tumbling and heat in a hot rotary dryer, and wherein the bag has an opening comprising a fastening system so that the bag can enclose a fabric article in an effective vapor impermeable manner;
