Research aimed at the investigation of physical chemistry processes in non-equilibrium gas-discharge plasma and at the creation of technologies using plasma have been conducted in Ivanovo for more than 30 years. As a result, several generations of industrial plasmo-chemical reactors for fabric treating were produced which are used in several Russian and European textile plants. Being absolutely safe ecologically, plasma treatment can solve many problems in pretreating, dyeing, and finishing textiles.

The application of vacuum plasma causes the initiation of the whole spectrum of chemical and radical-chemical processes, irrespective of the type of process. That is why such plasma cannot be used in textile technologies which demand part of reactions to be stimulated, part of them to be suppressed - for example, bleaching. In order to broaden the possibilities of plasma activation methods, the group is trying to develop new technologies based on the activation by atmospheric pressure plasma of processes in solutions. In this way, several desirable results can be achieved simultaneously - high rates of required chemical processes in solution, highly selective impact upon different chemical reactions, operation at atmospheric pressure. Consequently, plasma applying technological stages become much simpler and can be easily combined with other operations within a textile technology.

The scientific interests of the group are primarily concentrated on the following problems:
 bullet5.gif (101 bytes)   Interaction of non-equilibrium vacuum plasma with polymer films and fabrics. The use of plasma to modify the properties of polymer film and fabric. The creation of engineering methods for plasma chemical reactors calculations and for the optimization of modification processes;
 bullet5.gif (101 bytes)   Kinetics of homogenous oxidation processes initiated by quasi-stationary plasma in electrolyte solutions involving organic, inorganic substances and dyes. The nature of plasma-generated oxydizing agents, the mechanisms and kinetics of the processes of the formation and transformation of these agents, the interactions between primary and secondary particles;
 bullet5.gif (101 bytes)    Processes of modifying and finishing textile polymeric materials in plasma activated solutions;
