Abstract: The leather is treated with a resin, quaternary ammonium compound, amine or polymer before the impregnation with the fluoro chemicals. With these auxiliaries, a uniform effectiveness of the fluoro chemicals which act on the surface is achieved, regardless of the procedure or the chemicals previously introduced into the leather. These auxiliaries can optionally also be applied to the leather together with the fluoro chemicals.

Abstract translation: 在用氟化学品浸渍之前，用树脂，季铵化合物，胺或聚合物处理皮革。 使用这些助剂，可以实现作用于表面的氟化学品的均匀有效性，而不考虑先前引入皮革的程序或化学品。 这些助剂还可任选地与氟化学品一起应用于皮革。

Abstract: The process for the short-term preservation of rawhides and skins with an alkali metal chlorite solution which additionally also contains a compound of the formula 1 ##STR1## in which R denotes hydrogen or C.sub.1 -C.sub.12 -alkyl, Me denotes hydrogen or an alkali metal atom and n denotes 1 or 2. Because of their hydrotropic action, the addition of these compounds improves uniform penetration of the preservation solution into the hide.
