    摘要: The invention is a process for oiling of leather and skins which imparts washing and dry-cleaning resistance to the treated leather and skins and a composition useful in the process. The washing and dry-cleaning resistance of leather is improved by impregnating the leather with an aqueous dispersion of a co-oligomer containing residues of a partial ester of maleic acid and acrylic acid and/or methacrylic acid and optionally up to 45% by weight of residues of ether hydmphilic and oleophilic monomers. The composition can contain semiesters of sulfosuccinic acid as additional oiling agents.

    摘要: The invention concerns a method of preparing preferably highly concentrated aluminum triformate solutions containing alkali metals and/or alkaline earth metals, by the neutralization of an alkaline aluminate solution containing alkali metals and/or alkaline earth metals by adding formic acid, and subsequently heating the solid precipitated to give a clear, stable aluminum triformate solution. The invention also concerns highly concentrated aluminum triformate solutions containing alkali metals and/or alkaline earth metals and the use of such solutions to impregnate textiles, in disinfectant and cleaning agents, as a coagulant for paints, or as a setting agent in leather processing.

    摘要: Described is the use of at least substantially storage-stable supersaturated and acidified aqueous solutions of mixtures of aluminum triformate and alkali-metal and/or alkaline-earth formates as a means of supplying a water-dissolved mineral tanning agent based on aluminum formate for the tanning of leather and/or hides using little or no chromium. The invention thus concerns, in particular, storage-stabilized supersaturated and acidified aqueous solutions of this kind which also contain small quantities of stabilizers, preferred stabilizers being 1,2,3,4-butanetetracarboxylic acid and/or xanthane gum. The invention also concerns the use of such stabilized supersaturated aqueous forms of aluminum triformate solutions for use as tanning auxiliaries with a fixing and/or tanning action in the tanning or finishing of leather and hides.
