Abstract
The method of obtaining the leather resides in the treatment of cattle hides and includes the following successively performed operations: pretreating a raw hide, splitting it longitudinally to the thickness of 2.0 to 2.5 mm of the leather tissue, flushing the thus obtained grain split in an aqueous solution containing surface-active agents and ferments, pickling, tanning, shaving, greasing, drying, rolling, stretching and grinding. All the above operations are performed with the hair remaining on the unfinished leather. As a result of the disclosed treatment there is obtained the leather with hair and with the suede finish of the flesh side. The leather is suitable for production of warm shoes, with the hair inside and no lining.
