FIELD: process engineering.
SUBSTANCE: all layers of undercoat and finish paint are applied on leather subjected, prior to drum painting, to low-temperature non-equilibrium plasma of high-frequency discharge. Exposure is performed for 241 to 280 seconds in discharge chamber at 26.7 to 30.0 Pa, flow rate of plasma-forming argon making 0.041 to 0.06 g/s at discharge power of 0.7 to 2 kW.
EFFECT: increased depth of paint penetration, improved quality of ready leather.
