Definitions

  • My present invention relates to a method of and an apparatus for removing water-soluble spots and stains from garments and other textiles to be dry-cleaned.
  • the general object of my present invention is to provide an improved system for spotting textiles to be dry-cleaned, in order to foreshorten the time needed for treatment with the organic solvent.
  • my invention aims at performing this spotting operation automatically and in the same vessel as the subsequent dry-cleaning phase.
  • the present invention is based on the surprising discoveiy that garments and other textiles, when subjected to agitation in a treatment vessel such as a rotary drum, can be readily freed from water-soluble stains by admitting steam along with a detergent into the moving vessel in the absence of organic solvent. With the moistened textiles rubbing against one another, the stains wetted by detergent generally disappear in a relatively short time so that the overall operating cycle of the machine is shorter than when a similar stain-removing effect is to be achieved by the use of a water/solvent mixture.
  • the wet but not Water-soaked textiles can be subjected to the conventional dry-cleaning cycle, with possible intercalation of the venting phase to remove excess moisture from the vessel.
  • FIG. 1 is a diagrammatic isometricview of an apparatus used for practicing the invention.
  • FIG. 2 is a schematic layout of a system for operating an apparatus of the general type shown in FIG. 1.
  • a dry-cleaning machine with a housing 1 in which an upwardly open drum 2 is supported in a bearing 3 for rotation about an inclined axis 0 by a driving motor not shown.
  • the rotation can be continuous or oscillatory.
  • a source of steam not shown, is connected to a supply conduit 4 which opens into the drum at its upper end and terminates in a nozzle 32.
  • a source of detergent also not shown, feeds a conduit 5 which merges with the steam conduit 4 and is provided with a valve 7 controlling the amount of detergent to be admixed with the steam
  • Valves 6 and 7 may be operated in timed relationship, e.g.
  • an inlet conduit 8 and an outlet conduit 9 are part of a circuit, not further illustrated, for admitting organic solvent into the drum 2 and removing it therefrom.
  • FIG. 2 shows a more elaborate system wherein a perforated drum or basket 2' is rotated about a horizontal axis in a housing 1' having an access door 2b, the drying mechanism being accommodated in a base 12 also having a compartment 12a for the solvent. Conventional mens, not shown, may be provided for recovering and purifying the spent solvent to return it to compartment 12a.
  • Conduit 4' is connected via a regulating valve 6' and a Venturi-type constriction 36 as well as a shut-01f valve 14 and a steam drier 13 to a source of steam 41; a water tank 42 discharges into a pipe 19 connected by way of a shut-off valve 20 and a regulating valve 21 to constriction 36 for the purpose of varying the moisture content of the drum atmosphere.
  • a switching valve 15 connects conduit 5' to one of three supply conduits 16, 17 and 18 provided with respective shut-off valves 22, 23 and 24, conduit 16 originating at a detergent reservoir 25 whereas conduit 17 is connected through a pump 28 with an alternate detergent supply 29 shown to be mounted on a carriage 30.
  • Conduit 18 leads back to solvent compartment 12a by way of a pump 27.
  • Storage receptacles 25 and 29 are connected to an airpressure duct 26 into which compressed air from a tank 43 can be discharged through a control valve 44.
  • Valves 6, 7', 15,, 21 and 44 are under the control of a progra'mmer 31, with interposition of two manually settable timers 6a, 7a between the programmer and the valves 6' and 7'. With the aid of these timers the operator may select variable periods for the admission of steam and detergent into housing 1'.
  • he drum 2 and its housing 1' can be vented through an exhaust channel 38 which includes a blower 37 and terminates at an outlet port 39.
  • a damper 40 allows the vapor from the drum and the housing to be recirculated to the drum by way of a condenser and an air heater 11 whereby excess moisture can be removed between the pretreating phase and the dry-cleaning phase.
  • Slide valve allows for a switchover between difierent types of detergents stored in containers 25 and 29, aside from admitting the solvent to the drum during the dry-cleaning phase.
  • a nonionic detergent from tanks 29 could be introduced into the drum during or just prior to the admission of solvent, to replace a strong ionic detergent from container 25 introduced with the steam in the preliminary phase.
  • FIG. 2 is representative of a wide variety of automatic, semi-automatic or manual systems for practicing the process of my invention by successively treating textiles within a moving vessel in an aqueous and an organic phase.
  • the timers 6a, 7a may be so adjusted that steam (with or without an admixture of additional water) is allowed to pass the valve 6' before the valve 7' is opened so that the load is uniformly moistened when the detergent is first admitted.
  • a method of cleaning textiles in a continuously moving vessel comprising the steps of placing a load of textile in the vessel in the absence of organic solvents, setting the vessel in motion, admitting steam and a detergent into said vessel to lift water-soluble stains from said textiles, subsequently treating said textiles with a dry-cleaning fluid in said vessel, and thereafter drying said textiles.
