    Abstract: The present invention relates to water-soluble, acid-groups-containing graft copolymers which are at least partially biodegradable and are based on sugars and monoethylenically unsaturated carboxylic acids, sulfonic acids and/or phosphonic acids or the salts of said acids as well as optional further monomers. The present invention further relates to a process for producing the graft copolymers at temperatures of up to 200.degree. C. by means of radical polymerization initiators, in that a total mixture of 5-60%-wt. mono-, di- and oligosaccharides, the derivatives thereof or the mixtures thereof, and 95-40%-wt. of a monomer mixture comprising at least one monoethylenically unsaturated carboxylic acid, at least one monoethylenically unsaturated sulfonic acid, one monoethylenically unsaturated sulfuric acid ester and/or vinylphosphonic acid or the salts of said acids with monovalent cations, as well as optional further monomers is polymerized. The present invention further relates to the use of the graft copolymers in aqueous systems, for binding multivalent metal ions, inhibiting the water hardness, as additive in detergents and cleaning agents, as textile auxiliary, dispersing agent, in particular for pigments, and as auxiliary agent in the production of paper and leather.

    Abstract: A method and apparatus for bleaching and cleaning fibers of a fiber web. The method and apparatus includes continuously forming and moving a fiber web through a bleaching and cleaning station. Directing ultraviolet light onto the surface of the fiber web forming a bleaching and cleaning line. Selecting an intensity and frequency for the ultraviolet light sufficient to separate micro trash and dust from the fibers while simultaneously destroying pigment of the fibers. Collecting and removing the micro dust and trash while conveying the fiber web to subsequent fiber processing apparatus.

    Abstract: The present invention encompasses, in a process which comprises the steps of laundering or otherwise moistening fabrics using an aqueous medium, thereby securing damp fabrics and, thereafter, subjecting said damp fabrics to a drying process in a mechanical apparatus, the improvement which comprises: conducting said drying process by placing said damp fabrics in a vapor venting containment bag and drying said fabrics, thereafter removing said fabrics from said bag, whereby fabric shrinkage and wrinkling are minimized. The process herein is especially useful when the fabrics are cotton.

    Abstract: A method for cleaning objects in a pressure vessel with liquefied gases is provided. The gas liquefied under pressure is conducted into the pressure vessel. The temperature of the liquefied gas then, or beforehand, is lowered below the critical temperature of the gas and cleaning is performed at least primarily below the critical temperature and below the critical pressure of the gas. Carbon dioxide at temperatures between -20.degree. C. and +20.degree. C. is especially suitable. The mechanical interactions produced by the increased density and viscosity of the liquefied gas reinforce cleaning. Reduced solvent capacity does not influence the effectiveness of the cleaning. Textiles or components can therefore be cleaned at lower pressure and temperature.

    Abstract: A method of dry cleaning fabrics using a dry cleaning system is described. The system comprises densified carbon dioxide, preferably in a liquid phase, and a selected surfactant which is soluble in the densified CO.sub.2. The surfactant has a polysiloxane, a branched polyalkylene oxide or a halocarbon group which is a functional CO.sub.2 -philic moiety connected to a CO.sub.2 -phobic functional moiety. The surfactant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.
