Abstract: A method for cleaning garments. The garments are spread out in the interior of a cylinder (1) of a cleaning machine, attached there with bands (7) and hangers (10) and cleaned in this manner. By the method shrinkage and wrinkles will be avoided. Spin drying following cleaning and rinsing can be carried out at high speed, because the centrifugal forces act on garments which are spread out and lying flat and hence the forces do not create unwanted creases and wrinkles. The cleaning and spin drying will be followed by drying the spread out and attached garments by supply of heat. An ironing effect is improved by an intermediate spin speed. This method is suitable especially for cleaning in aqueous solutions. The garments are attached to the interior of the cylinder (1) by bands (7) with loops (8) connected to hooks (5). The solvents used for cleaning enter through the aqueous duct (11) and the hot air for drying enters through air duct (12).
Abstract: Apparatus in accordance with the invention is of the type in which textile fabric samples are dyed in a generally cylindrical vessel containing a liquid dyeing bath while being moved in a cyclical fashion by a sample holder having a generally vertical rod connected to an overhead stirrer. The improved apparatus includes means connected to the generally vertical rod for holding the textile fabric sample in a generally cylindrical configuration, a pump for pumping a concentrated chemical solution at a controlled rate, and means for supplying the concentrated chemical solution from the pump under the surface of the dyeing bath in at least two vertically spaced-apart locations.
