FIELD: material processing.
SUBSTANCE: method provides degreasing and/or drying of animals' skins. According to method, skins, being subject to degreasing and/or drying, are brought in contact with one or more extractants. At least one dissolvent, selected from group consisting of dimethyl ether, methylal, dioxolane, diethyl ether and methyl ethyl ketone, is used as single dissolvent. Sheep, cows', goat's or pig's skins are subject to degreasing and drying. Process is carried out in stator or rotor reactor under pressure of 1-12 bar and at temperature between 5°C and 40°C.
EFFECT: improved efficiency of cleaning; improved ecological safety of process.
