    摘要: The present invention relates to a process to improve the organoleptic behaviour and the physical characteristics of leather by the use of aqueous solutions of copolymers of 90 to 20%-wt acrylic acid or methyacrylic acid, as well as 10 to 80%-wt of a monomer of the formula ##STR1## wherein R.sub.1 is hydrogen or methyl; R.sub.2 and R.sub.3, which are equal or different, are methyl or ethyl; x stands for an optionally branched alkylene radical with 1 to 5 carbon atoms; the amine nitrogen is optionally neutralized or quaternized; and the molecular weight of the copolymer, measured at a pH of 8.0, is less than 100,000. The concentration of the copolymer in the aqueous solution is 0.02 to 10%-wt, relative to the shaved weight of the leather.

    摘要: The present invention relates to a process for improving the waterproofing of hides, skins, leathers, and furs, as well as other fibrous materials, by treatment with special surfactants in the beamhouse and/or in the treatment of the wet blues, prior to waterproofing. Particularly suitable as surfactants are anionic surfactants based on salts of N-acyl-amino acids and nonionic surfactants, such as alkyl polyglycosides or polyethyleneglycol carboxyalkyl ethers. The surfactants are used in amounts of 0.5 to 5% wt., relative to the pelt or shaved weight.

    摘要: A process is disclosed for waterproofing materials having a fibrous structure, such as leather, persian leather or leather replacement materials, by using waterproofing agents containing sulfosuccinic acid esters. Also disclosed are waterproofing agents used to carry out this process. The sulfosuccinic acid esters are prepared by reacting maleic anhydride with monohydric or polyhydric alcohols, then by sulfitizing them. Reactive siloxanes may also be used as polyhydric alcohols.

    摘要: The present invention relates to a process for waterproofing leathers, furs and other fibrous materials wherein waterproofing is carried out with conventional water repellents in the presence of dispersing or stabilizing auxiliary agents at pH-values of 3.5 to 5. Alkoxy-groups-containing copolymers, synthetic or natural fatliquors and/or synthetic retanning agents (syntans) are preferably used as dispersing or stabilizing auxiliary agents.
