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

Investigations, which are related to plasma efficiency on the treated leather surface, significant in development of ecologically and economically friendly processes obtaining material desired functional properties. Through pretreatments using different chemical-physical reactions surface layer occurred resulting improved reactivity. In this paper, modification functionalization bovine 1,2,3,4-butantetracarboxylic acid chitosan were explored. Pretreatments samples realised argon oxygen assess various influence chemically reactive inert gas. Two leathers -chrome tanned with synthetic tanning agent (Cr-free) chosen for treatments. Analyse morphology was conducted SEM microscopy, while chemical changes ATR-FTIR spectroscopy. Antimicrobial effectiveness tested qualitative Agar diffusion plate test against two bacterial Staphylococcus aureus Klebsiella pneumoniae . Obtained results indicated how applied optimized process conditions contribute improvement Achieved positively affected reactivity antimicrobial effectiveness, particularly Cr-free leather.
