Verfahren zur Behandlung von Häuten, Fellen, Ledern und Pelzen mit Tensiden zur Verbesserung der Hydrophobierwirkung und zur Angleichung qualitativ unterschiedlichen wet-blue-Materials |
摘要 |
A process is disclosed to improve water-proofing of skins, fells, leathers and pelts, as well as other fibrous materials, by treating them with special surfactants in the wet finishing workshop and/or when treating the wet blue leathers before water-proofing. Anionic surfactants based on salts of N-acyl-aminoacids and non-ionic surfactants such as alkylpolyglycosides or polyethylene glycol carboxyalkyl ethers are particularly suitable. The amount of surfactant used lies between 0.5 and 5 % by weight, with respect to the weight of the smoothed or shaved skins.
