Abstract

1. A process for the soaking and liming of hides and skins by treating the dried or salted hides and skins with a conventional soaking or liming liquor under conventional conditions with respect to temperature, liquor length and use of chemicals, wherein instead of surfactants there is used, in the case of hides, from 0.2 to 2% by weight (based on salted or limed weight), and in the case of fur skins, from 0.2 to 2 g per liter of liquor, of a water-soluble sodium salt or ammonium salt of a homopolymer or copolymer of acrylic or methacrylic acid or maleic acid, the copolymer containing, as polymerized units, at least 20 mole per cent of a monomer possessing one or more carboxyl groups, and the homopolymer or copolymer having a Fikentscher K value of from 10 to 150.
