Abstract

Processes and apparatuses for commercial and home-use cleaning of textile. Home-use embodiments replace the home laundry clothes dryer, except for embodiments using a novel manual kit. Home-use embodiments have an integrated spotting station. Soiled/stained textile is spray dampened with solvent, preferably automatically in the apparatus'"'"' rotatable drum; but the textile is not soaked nor immersed in solvent. Highly absorbent, untreated pad material is placed into the drum, for rubbing against the tumbling textile, to remove the soil, stains and solvent.

10. Apparatus according to claim 9 in which,

said spraying and dampening means includes automatic spraying equipment, for spraying into said drum at least one of said solvent, air, steam or water, without soaking or immersing the textile in said drum.

11. Apparatus according to claim 9 in which,

said drum is rotatable bidirectionally;

and

said spraying and dampening means is positioned and controlled to operate distinctively, depending upon the direction of drum rotation.

12. Apparatus according to claim 1 in which,

said rotatable drum is controlled to have a dwell time;

and

said spraying and dampening means is controlled to operate distinctively during said dwell time.

13. Apparatus according to claim 1 in which,

said spraying and dampening means is constructed for manual use, exterior to said machine.

14. Apparatus according to claim 13 in which,

said pad material and said spraying and dampening means are part of a manual use kit.

15. Apparatus according to claim 1 in which,

a spotting board is vacuum coupled to said machine;

and

said machine is a home-use clothes dryer.

16. Apparatus according to claim 1 which, said drum has:

means for venting air flow out therefrom; and

venting regulating means, positionable to control the amount of venting air flow and thereby control the hydration of said pad material.

7. Apparatus according to clam 1 in which,

said pad material is in the interior of a textile containment bag.

8. Apparatus according to claim 7 in which,

said containment bag and said spraying and dampening means are part of a kit.

17. A textile cleaning kit for manual use in the cleaning of textile in a home-use clothes dryer having a rotatable drum;

said kit including;

spraying means for spraying cleaning liquid onto the textile, only to dampen the textile, and other than for spotting, prior to the textile being placed into the drum; and

highly absorbent pad material to be place into the drum;

whereby,

rotation of the drum causes rubbing contact between said pad material and the dampened textile, for transfer of soil and liquid from the textile to said pad material.

18. A kit according to claim 17, also including:

control means for controlling the venting of air flow from the drum, so as to extend the duration of hydration of the dampened textile.

19. A kit according to claim 18, wherein said clothes dryer includes a lint filter for venting air from the drum;

and

said control means comprises structure for at least partially blocking the lint filter.

20. A kit according to claim 17, in which said pad material is in the interior of a textile containment bag.

21. In a process for cleaning textile in a rotatable drum of a machine, the steps of:

dampening the textile with liquid other than for spotting, in the absence of soaking or immersing the textile in any liquid;

placing highly absorbent pad material into the drum;

rotating the drum, thereby;

causing the textile and pad material to tumble against each other, to effect;

rubbing transfer of the liquid and soil from the textile to the pad material.

22. In a process according to claim 21, said placing being by;

securing detachably the pad material into tho drum.

23. In a process according to claim 21,

employing felt as the pad material.

24. In a process according to claim 21,

utilizing the pad material as a source of hydration for the textile in the drum.

25. In a process according to claim 21,

spraying automatically the textile in the drum with liquid from a source positioned exterior said drum.

26. In a process according to claim 25,

controlling said spraying to be in conjunction with rotation of the drum.

27. In a process according to claim 26,

programming said rotating and said controlling to provide reversible rotating of the drum, with a dwell time;

and

spraying distinctively in each direction of rotating and during dwell time.

28. In a process according to claim 21, the added step of:

spotting the textile while using a spotting board; and

coupling to the spotting board vacuum generated by the machine.

29. In a textile cleaning kit for manual use in the cleaning of textile in a home-use clothes dryer having a rotatable drum, said kit including:

highly absorbent pad material to be placed into the drum, whereby,

the textile only being dampened by liquid, other than for spotting, prior to the textile being placed into the drum and not being soaked or immersed in any liquid in the drum; and

rotation of the drum causes rubbing contact between said pad material and the dampened textile, for transfer of soil and liquid from the textile to said pad material.
