  • Patent number: 6094840
    Abstract: A method for the heat treatment of textiles, particularly advantageous for textiles wound on cops or bobbins, comprises applying a vacuum to a steamer chamber in which the textiles have been placed. When a sufficient vacuum has been reached a treatment liquid is introduced and the vacuum source shut off maintains the vacuums. The treatment liquid is then heated to generate a saturated steam treatment for the textiles. The liquid and steam are then pumped out of the chamber and a vacuum re-instituted for evacuation, cooling and drying, after which the chamber is returned to ambient. Subsequent cycles may be performed with other liquid treatments. An apparatus for carrying out the method may be in the form of a closed system in which the vessels from which the liquid treatment are drawn are coupled to the treatment chamber to allow return of the liquids when the liquids are pumped out. Liquid loss is thus minimized and efficiency increased.

  • Patent number: 5651276
    Abstract: Substantial amounts of particulate soils in garments can be removed by agitation in gas-jet in a solvent-free, low-pressure environment. The ability of the present gas-jet agitation system to remove particulate soils from garments and fabrics rivals that of conventional dry-cleaning processes which agitate the garments and fabrics while immersed in solvent. Thus, a dry-cleaning operation may consist of a solvent-immersion step for removing soluble soils and a gas-jet agitation step to remove particulates. Considerable savings in equipment and operating costs may be realized in the practice of the invention, since solvent flow rates need not be boosted to provide necessary agitation for particulate soil removal. The savings achievable by employing gas-jet agitation are even more pronounced in dense phase gas dry cleaning systems, which require pressurized environments to maintain a liquified solvent.

  • Patent number: 5172443
    Abstract: In a method for wet-finishing textile goods in the extraction process, the textile goods are made-up in the form of spools or in packages. They are placed in this made-up form in a vessel closable in a pressure-tight manner and the air is then at least substantially removed from the interstices in the textile goods. In the course of the method, the liquor present in the form of an aerosol is made to flow through the textile goods. In order to reduce the water and energy consumption and to also improve the quality of the treatment, the textile goods are first transferred to a state with increased temperature and low residual moisture. Subsequently or or simultaneously, the air is at least substantially removed from the interstices in the textile goods, and after this state has been attained, a gaseous medium under increased pressure which together with the liquor forms an aerosol is made to flow directly through the textile goods.

  • Patent number: 5123134
    Abstract: There is described herein an improved method for decatizing in an autoclave wherein steam is led into the jacket surrounding said autoclave, at a pressure level increasing up to a stationary level within the autoclave. That is obtained by means of an automatically and adjustably controlled throttling valve at the steam inlet to the jacket, the valve being for instance driven by means of a microprocessor routine, and having an autoclave inlet valve associated therewith. In case the outer jacket is missing there might possibly be provided only an automatically controlled autoclave inlet valve performing also as a throttling valve, in order to have a gradually increasing inlet pressure.

  • Patent number: 4922567
    Abstract: A method for preshrinking tubular knit fabrics in which the fabric is treated as a continuous length in tubular form. The elongated tube is continuously fed lengthwise into a series of liquid baths which include a wetting agent, scouring and washing constituents and rinses and any finish is to be applied to the fabric. The fabric tube is caused to advance into and through the bath in a substantially tensionless state by pushing the fabric into the flow of liquid and through the bath to avoid applying substantial tension. From the washing and rinsing baths, the saturated fabric is flattened, again without application of substantial tension, and is fed through a two-stage dryer. In the initial stage, the fabric is air-dried to a moisture content of substantially less than 40%. Before introducing the fabric into the second stage of the dryer, the moisture content is raised, for example in a steam atmosphere, to substantially 40%.

  • Patent number: 4903509
    Abstract: In industry there is, for economic reasons, an urgent need to be able to carry out the drying of moist textile material immediately after a completed wet-treatment in the same apparatus in which the preceding treatment operation was carried out.According to the invention the problems arising in the case of textile materials treated in rope form on jet units are solved by evaporatively dewatering the textile material in rope form by means of the gaseous agent which in the case of fabric-advancing jet systems operated by flowing liquor, steam or hot air takes over the transport of the goods immediately after the wet-treatment and which acts on the textile material under a predetermined variable superatmospheric pressure, then cooling the circulating drive gas to condense out the absorbed moisture, and recirculating the air thus dried.

  • Patent number: 4903363
    Abstract: A dye setting apparatus for use with carpets, mats and the like comprises a cover having a generally planar interior surface pivotally connected to a support surface. The cover includes a steam containment and support structure having an interior channel flow connected to a steam source. The cover, support structure and support surface form a confinement chamber for the carpet. Steam is released into the chamber from apertures in the support structure to set dye in the carpet. The interior surface of the cover is constructed of a material which is generally non-heat conductive and somewhat water absorbent, such as plywood, to prevent steam from condensing as droplets on the interior of the cover and dropping on the carpet during dye setting. An alternative embodiment includes multiple stacked covers that form multiple chambers, each chamber adapted to receive a mat and steam therein such that dye may be set on multiple mats simultaneously.
