FIELD: fur industry, in particular, process for pickling of sheepskin fur coats and raw fur material.
SUBSTANCE: method involves pickling fur sheepskins in solution such as sour-milk composition having titratable acidity of at least 300 T, lactic acid concentration of at least 25 g/dm3 and medium active reaction below 3.5; providing said process at temperature of 30±2 C during 16 hours at variable mechanical action, with liquid to acid ratio of 7, sodium chloride consumption of 20 g/dm3.
EFFECT: improved quality of fur sheepskins due to reduced curling of hair-covering and improved elastoplastic properties thereof.
