Modification of Leather Surface Using Low-Pressure Plasma and Antimicrobial Reagent

Investigations, which are related to plasma efficiency on the treated leather surface, are significant in the development of ecologically and economically friendly processes in obtaining material of desired functional properties. Through the pretreatments using plasma different chemical-physical rea...
