    Abstract: Residual moisture and sulfur and other residual reducing agent impurities contained in drycleaning solvents are removed by adding to the solvents an unsubstituted aromatic hydrocarbon or a halogen or alkyl substituted aromatic hydrocarbon and circulating the hydrocarbon-containing solvent through a filter system comprising two filters; one filter containing a solid acid and the other containing chromate compound.

    Abstract: Method and apparatus for treating a textile fabric with a volatile organic solvent and the resulting treated fabric which comprises, in cooperative sequence, pretreating said fabric in a pretreat stage by sequentially preheating to remove volatile materials and then cooling, followed by applying said solvent to the fabric in an application stage and then drying the fabric by evaporation and condensing and recovering the evaporated solvent in a drying and recovery stage, followed by recycling the recovered solvent back to said application stage. The invention has particular utility by providing a method which enables the recycling of the organic solvent from a fabric treating process and, therefore, provides an improved treated fabric.

    Abstract: Residual moisture and sulfur and other residual reducing agent impurities contained in dry cleaning solvents are removed by adding to the solvents an unsubstituted aromatic hydrocarbon or a halogen or alkyl-substituted aromatic hydrocarbon and a cellulosic container device. The cellulosic container device comprises a cellulosic bag which contains another cellulosic material on which has been coated a chromate compound, the chromate compound being sealed onto the cellulosic material by use of a polymeric material or a cellulosic gum, the cellulosic bag also having attached thereto one or more copper wires to provide a continuous electrical ground to the vessel containing the solvent or to a D.C. power supply. The same cellulosic container device can be added to petroleum liquids together with naphthalene and fatty acids to remove sulfur impurities therefrom.

    Abstract: This invention relates to the use of a limited specie of glassy rhyolite, specifically pumicite as a filter aid for the cleaning of solvent in the drycleaning industry. The invention is particularly directed to the new and unexpected results accruing from the use of pumicite for accomplishing extremely low, non-volatile levels in the solvent and for also removing objectionable fatty acids and odor from the solvent while simultaneously making its distillation unnecessary and removing sufficient moisture to give clothes a softer feel, and fewer wrinkles.
