Abstract
The study results of loading effect when acting a low temperature air plasma on the surface of the fabric from poly(ethylene terephthalate) complex strings are resulted. Gravimetric and mass-spectrum tech- niques were used in this work. Gas evolution changes plasma properties and as a consequence the purposeful process kinetics. Because of mutual influence of heterogeneous and volumetric processes not only flows of active oxygen particles on the material surface reduce but and correlations of these flows changes. NO mole- cules concentration is closely connected with atom oxygen balance. Even a fraction of a reactor surface oc- cupied by the fabric is relatively low NO molecules concentration is drops appreciably. For wide interval of discharge parameters specific rates of etching, oxygen absorption from gas phase and gaseous products for- mation as well as NO molecules concentration decrease extensively when reactor load degree is increased from 6% to 50%. Interconnected influence of parameters and load tells on behaviors of reaction products formation. In case of load degree rise correlation of degradation channels changes to a channel with separa- tion of CO and H2 and the more the higher initial gas pressure.
