Abstract:
The present invention provides a dry cleaning process for the in-home dry cleaning of laundry articles, comprising one or more cleaning steps followed by one or more rinse steps whereby at least one rinse step comprises contacting the laundry article with a rinse composition, said rinse composition comprising a low grade non-flammable non-chlorine containing organic dry cleaning solvent and said low grade solvent comprising at least 0.1 ppm and less than 50 000 ppm of squalene.
Abstract:
A method of recover dry cleaning solvents from a mixture containing a used dry cleaning solvent and contaminants, such as laundry soils, fabric treating agents. Specifically, purification agents are added to the mixture to effect a change in the mixture such that the contaminants become less soluble in the mixture and can be easily separated from the dry cleaning solvents.
Abstract:
A process for purifying a lipophilic fluid employing a functionalized fabric treating agent. The functionalized fabric treating agent is capable of delivering fabric treating benefits in a non-aqueous fabric article treatment process and is designed for easy removal from the non-aqueous solvent after the fabric article treatment process. Laundry soils can also be removed by this process. The present invention also relates to a fabric treatment composition containing the functionalized fabric treating agent.
Abstract:
Compositions for treating fabric articles, especially articles of clothing, linens and drapery, wherein the compositions provide improved cleaning of soils from and/or care of and/or treatment of fabric articles, especially while providing superior garment care for articles sensitive to water as compared to conventional fabric article treating compositions, are provided.
Abstract:
The present invention relates to compositions and methods for improving the visual properties of a wash process which utilizes lipophilic fluid (e.g., siloxane solvent) by coloring agents, sudsing agents and mixtures thereof.
Abstract:
Bei der Aufbereitung durch Filtration und Destillation wird als Filtermasse ein feinteiliges, wasserunlösliches, gebundenes Wasser enthaltendes Aluminiumsilikat der allgemeinen Formel: (Kat 2 O) x ·Al 2 O 3 .(SiO 2 ) y , Kat=Alkalimetall, insbesondere Na, x = 0,7-1,5, y = 0,8-6 (1,3-4), verwendet. Das Aluminiumsilikat kann röntgenamorph oder kristallin sein und eine Teilchengröße im Bereich 1-100µ aufweisen. Bevorzugte Aluminiumsilikate sind die Zeolithe NaA und HS und deren Gemische. Die Aluminiumsilikate werden bevorzugt im Gemisch mit dem üblichen Kieselgur eingesetzt, vorzugsweise in Mengen von 5-50 Gew.-% Aluminiumsilikat. Durch den Gehalt an austauschbaren Alkaliionen sind die Aluminiumsilikate imstande, die durch Zersetzung der Chlorkohlenwasserstoffe gebildeten Säuremengen, die Korrosionen an den Reinigungsmaschinen bewirken, zu neutralisieren, wenn regenerierte Lösungsmittel eingesetzt werden. Das Verfahren ist besonders zur Regenerierung von Trichlorethylen, Tetrachlorethylen oder 1,1,1-Trichlorethan geeignet.

Abstract:
The present invention relates to processes for removing contaminants from lipophilic fluids, adsorbent materials employed in such processes, and lipophilic fluids produced by such processes.
Abstract:
The present invention relates to systems for controlling a drying cycle in a drying apparatus by monitoring the lipophilic fluid vapor concentration. The systems utilize a gas sensor capable of sensing the concentration of lipophilic fluid vapor in the drying apparatus drum or a combination of sensors/condition detectors, at least one of which is capable of sensing the concentration of lipophilic fluid vapor in the drying apparatus drum.
