INFLUENCE OF MODIFICATION BY LOW-ENERGY IONS FLOW ON HEAT RESISTANCE AND POROSITY OF WOOLLY SHEEPSKIN SEMI-FINISHED PRODUCT

The article deals research results the influence of low energy ions generated from the positive charge layer radio-frequency capacitive discharge on the quality indicators of woolly sheepskin. It was found low energy ions treatment of semi-finished product before the retanning process promotes intensification of tanning agent diffusion inside the hide tissue. The influence of ionic current density and ion energy on the heat resistance of woolly sheepskin is shown. The fat liquor emulsions diffusion degree depending on the modification parameters was investigated by porosity and fat content indicators. The influence of plasma modification parameters on physical and mechanical indicators of woolly sheepskin semi-finished product was also established.
