A method for processing tawery or tannery articles such as hides and leather whereby loosening of the fibers and internal fat distribution are effected in order to increase the hides' surface area and homogenize their thickness. According to the method, the hides or leather are contacted, during the manufacturing process, with methanesulphonate CH3 SO3<-> ions. In particular, this step may be carried out during the pickling and/or tanning and/or dyeing processes, especially by means of methanesulphonic acid optionally combined with another acid. Said method substantially improves product quality, particularly by allowing a cost-efficient enhancement of inferior quality hides. |
