FIELD: technological processes.
SUBSTANCE: invention relates to light industry and can be used for processing fur materials. Method of pickling of sheepskin fur raw materials that was subjected to plating ensures application of smearing composition, i.e. lactic acid composition having titratable acidity value 300˚T, lactic acid concentration of at least 25-30 g/dm3 and active reaction medium is not more than 3.5 and the products of collagen dissolution with an active reaction medium does not exceed 4.0, taken at a ratio of 2:1. Process is carried out at a temperature of 24±2˚C, the composition is applied with a brush with a subsequent holding for 30 min after the first and second deposition followed holding for 24 h and additional plating.
EFFECT: proposed method provides increase strength, ductility, and fullness of the leather finished fur skins.
