Abstract

The procedure comprises subjecting the skins to riverside works and, A) sammying the skins; dehydration and degreasing in a water miscible solvent; drying of said solvent; or B) sammying the skins; dehydration and degreasing in a water miscible solvent that comprises aliphatic hydrocarbons; drying of said solvent; or C) pickling; laying out; degreasing; acidification; sammying the skins; drying; or D) pickling; laying down; degreasing; acidification; pre-tanning with pre-tanning products; sammying of the skins; and drying; wherein said drying allows dry and frayed skins to be obtained and, next, a tanning stage by immersion in a solution of mineral salts, vegetable tannin extracts or mixtures thereof. This invention also provides a material obtained before the tanning, useful as a replacement for the skin tanned by conventional methods, as well as a device for dehydrating and degreasing the skins following option A) of the claimed procedure.
