Abstract: A load of garments or other textile material to be washed is presoaked in organic solvent, e.g. in a rotating drum, and is then immersed within the same vessel in a water bath while still permeated by a substantial quantity of solvent. During this immersion, the vessel is gradually heated to the boiling point of the solvent, or of the azeotropic water/solvent mixture, which is below the boiling point of water so that only a part of the wash liquor is vaporized. The evaporation can be accelerated by placing the vessel under a partial vacuum. The evaporation rate of the solvent is measured and the washing cycle is halted as soon as that rate drops to zero or below a predetermined limit, with subsequent drying of the load by, for example, centrifugation.

Abstract: This invention relates to a process for treating natural polyamidic fibres of asymmetric structure, particularly wool, with liquid ammonia, in which a nucleophilic substance is added to said liquid ammonia. The treatment time is thus reduced and the dye affinity is improved.An acetate, such as ammonium acetate is preferably used and excellent results are obtained on wool.

Abstract: A process for rendering cellulose and cellulose containing fabrics fire resistant by first impregnating the fibers with a solution of an aminoplast resin, an acid and an effective amount of a dialkyl phosphono methylol alkylamide to produce fire retardancy in the resulting fabric having the formula ##STR1## wherein R is lower alkyl having 1 to 6 carbon atoms and x is an integer from 1 to 3 and polymerizing the resin while the fibers are wet and swollen. The fabric is then cured, washed and dried. The fabric obtained from this process possesses high fire-retardancy values, soft hand, and tensile values similar to that of the untreated fabric.

Abstract: Constant boiling binary admixtures are formed by 1,2-dichloro-1,1,2-trifluoroethane with trichlorofluoromethane, with diethyl ether, and with dichloromethane. A constant boiling ternary admixture is formed by 1,2-dichloro-1,1,2-trifluoroethane, diethyl ether, and 1,2-dibromo-1,1,2,2-tetrafluoroethane.
