METHOD FOR DRESSING OF LEATHER SEMI-FINISHED GOODS Russian patent published in 2010 - IPC C14C9/00 C14C1/00 C14C11/00 C14C3/00 

FIELD: technological processes.

SUBSTANCE: method for dressing of leather semi-finished goods includes serial completion of preparatory and tanning processes, in which leather rawstock, especially from small breeds, for instance goat, prior to soaking process is exposed to low temperature unbalanced plasma of high frequency discharge for 420-600 seconds, with pressure of 30.1-39.9 Pa in discharge chamber, with flow of plasma-generating gas argon 0.06-0.08 g/sec, with current force at anode 0.5-0.8 A, with voltage of 3-5 kV at anode.

EFFECT: reduced time of rawstock treatment with increased value of boxcalf semi-finished product sealing temperature, being control index of tanning process.
