The study results of loading effect when acting a low temperature oxygen plasma on the surface of the Italian production fabric from poly(ethylene terephthalate) monofilament threads are resulted. Gravimet- ric and mass-spectrum techniques were used in this work. Contact time of plasma with the fabric example determines specific rates of heterogeneous processes if it is less then characteristic times of chemical reac- tions. Mutual influence of heterogeneous and volumetric processes has become appreciable only when con- tact times exceed characteristic times of chemical reactions. Consequently specific rates of etching, oxygen absorption from gas phase and gaseous products formation decrease when reactor load degree is increased. However correlation of degradation channels does not change. For wide interval of discharge parameters oxygen plasma as compared with air plasma is steadier to loading effect.
