Patent number: 7845197Abstract: A high efficiency triple pass tunnel finisher includes an articulated spraying function for allowing steam to effectively penetrate a garment. The tunnel finisher can be used for the laundering of shirts, pants, and jackets. The tunnel finisher includes hot air chambers and a steam chamber that can include two rows of steam injectors located at a 45° angle in relation to the walls of the module. The steam chamber has a lower pressure than the hot air chambers, creating an air pressure differential. The hot air chambers are positively pressurized, preventing the relatively cooler air of the steam chamber from entering the chamber. The pressurization prevents heat loss, allowing the finisher to be more efficient, while increasing the temperature at which the garments exit the steam chamber. This leads to faster drying times, less garment wrinkling, and reduced dwell time for a garment with a high quality appearance.Type: GrantFiled: December 19, 2006Date of Patent: December 7, 2010Assignee: Leonard Automatics, Inc.Inventor: Jeffrey Neal Frushtick

One method of non-aqueous clothes washing includes the steps of disposing clothing in a wash container, delivering a wash liquor to the fabric load, the wash liquor comprising a substantially non-reactive, non-aqueous, non-oleophilic, apolar working fluid and at least one washing additive, applying mechanical energy to the clothing and wash liquor for a sufficient amount of time to provide fabric cleaning and, thereafter, substantially removing the wash liquor from the fabric load. The working fluid may be selected from the group consisting of perfluorocarbons, hydrofluoroethers, fluoronated hydrocarbons and fluoroinerts.Type: GrantFiled: March 7, 2000Date of Patent: September 17, 2002Assignee: Whirlpool Patents Co.Inventors: Kurt A Estes, Daniel C. Conrad, Mark Bradley Kovich, Tremitchell L. Wright

Patent number: 6440363Abstract: The fungistatic/antibacterial treatment method for sewed goods like clothes according to the present invention is characterized by the steps of permeating the fungistatic/antibacterial chemicals into a variety of sewed goods like clothes after sewed, to be adsorbed thereby, followed by draining, and then drying by heating them with hot air in the state of being hung from hangers. Thus since the sewed goods to which the fungistatic/antibacterial chemicals have been applied are dried in the state of being hung from hangers, positive fixed adsorption of the fungistatic/antibacterial chemicals can be made, foreclosing uneven permeation of the fungistatic/antibacterial chemicals, which is usually unavoidably brought about by their contact with other objects, whereby highly wash resistant fungistatic/antibacterial treatment has been realized.Type: GrantFiled: March 25, 1999Date of Patent: August 27, 2002Assignee: Fukusen Kogyo Co., Ltd.Inventor: Katsumori Fukumoto

Patent number: 6425926Abstract: For thermosol treatment of surface printed textile, a printed textile is transported through a treatment space in its longitudinal direction. A heat source is arranged for emitting heat in the treatment space. A pressure drop is generated over the web in the treatment space from a first side of the web to an opposite, second side of the web for entraining sublimated ink on the first side of the web back to the web.Type: GrantFiled: May 4, 1999Date of Patent: July 30, 2002Inventors: Jakobus Hindriks, Peter Hollanders, Andreas Thomas Dorsch, Otto Arnout Richard Pennekamp

Patent number: 6369014Abstract: This invention is directed to a surfactant comprising a carbohydrate group that results in superior cleaning in a dry cleaning system. The surfactant has a hydrocarbon group that is more solvent-philic than a carbohydrate group, and can result in reverse micelle formation in a densified gas like densified carbon dioxide.Type: GrantFiled: May 24, 2001Date of Patent: April 9, 2002Assignee: Unilever Home & Personal Care USAInventors: Dennis Stephen Murphy, David Alan Binder

Patent number: 6346126Abstract: A soiled piece of fabric is cleaned by mechanical agitation while the fabric is simultaneously subjected to acoustic energy in a gaseous environment wherein the piece of fabric is not immersed in a liquid cleaning medium. Mechanical agitation may be by gas jet action and/or by tumbling. The acoustic energy vibrates the fibers of the fabric to enhance the cleaning action. The piece of fabric may be chemically treated to mobilize the soil.Type: GrantFiled: December 2, 1999Date of Patent: February 12, 2002Assignee: Raytheon CompanyInventors: Sidney C. Chao, Nelson W. Sorbo

Patent number: 6261326Abstract: A process for introducing a textile treatment material into a textile treatment system, particularly a supercritical fluid carbon dioxide (SCF-CO2) treatment system. The process includes the steps of providing a preparation vessel in fluid communication with a textile treatment system; loading a textile treatment material into the preparation vessel; dissolving or suspending the textile treatment material in near-critical liquid carbon dioxide or supercritical fluid carbon dioxide in the preparation vessel; and introducing the dissolved or suspended textile treatment material into the textile treatment system. The textile treatment material can be selected from a group including a brightening agent, a whitening agent and a dye. A system suitable for use in carrying out the process is also disclosed.Type: GrantFiled: January 13, 2000Date of Patent: July 17, 2001Assignee: North Carolina State UniversityInventors: Walter A. Hendrix, Gerardo A. Montero, C. Brent Smith, Donald L. Butcher
