METHOD FOR DEGREASING SHEEPSKIN-FUR RAW MATERIAL Russian patent published in 2003 - IPC

FIELD: fur production. SUBSTANCE: the present method deals with treating sheepskin-fur and sheepskin-fur coat raw material with enzymatic culture as Pseudomonas Sp. at the quantity of 10⁶ cells/cu. cm and bacterial preparation (BP) produced by this culture at the following parameters: BP concentration 1-2 g/cu. dm, SAS 0.5-1 g/cu. dm, at 40-42 C and constant mechanic mixing of working baths. The method enables to obtain optimal removal of fatty substances from hairy surface and sheepskin tissue by keeping the bond of hair with sheepskin and at decreased toxicity of waste water due to decreased expenses of SAS ranged 8-0.5-1 g/cu. dm and exclusion of sodium carbonate and formalin out of working bath. EFFECT: higher efficiency. 3 tbl
