Abstract (en)

[origin: EP0533011A1] In the production of chrome-tanned leather, a pretreatment of delimed and bated pelts with condensation products without a tanning action leads to substrates which can, by machine and without difficulty, be dehydrated and shaved or split and shaved. The properties of the leathers produced therefrom by chrome-tanning do not differ from those of conventionally chrome-tanned and shaved leathers.
