SKIN TREATMENT PROCESS

FIELD: leather industry. SUBSTANCE: before the first layer of coating dye is applied, skin is subjected to action of high-frequency discharge low-temperature nonequilibrium plasma in vacuum chamber for 300 to 600 s. Pressure in the chamber is 53.3 to 80 Pa and plasma-forming air consumption 0.04-0.0...

Zusammenfassung:	FIELD: leather industry. SUBSTANCE: before the first layer of coating dye is applied, skin is subjected to action of high-frequency discharge low-temperature nonequilibrium plasma in vacuum chamber for 300 to 600 s. Pressure in the chamber is 53.3 to 80 Pa and plasma-forming air consumption 0.04-0.06 g/s. Current strength on generator lamp anode is 0.2-0.6 A. Thereafter, several more coating dye layers are applied on skin. EFFECT: improved quality and adhesion of coating of chrome leather. 1 dwg, 1 tbl
