Application of corona treatment to modify the surface layer of textile polimer materials. Analysis of the issue, design of equipment, and preliminary studies
Abstract
The article shows the results of the designing and research work relating to a new set of equipment being intended for modification of the surface layer of textile polymer materials by the corona treatment. Based on the preliminary results it was found that the equipment commonly used presently for modification of the surface layer of polymer films by the corona treatment was useless in relation to modification of textile polymer materials. Although increase in the unit energy of the corona treatment with the latter system had improved the modification effects, the material being modified became thermally damaged to an unacceptable degree (Fig. 1-4). Therefore, a new design of the corona treatment unit was elaborated, which could modify the material several times using such a discharge unit energy that would not damage that material (Fig. 5-7). The new set of the equipment, based on this idea, includes two, three or four discharge electrodes placed in this set in series. The number of the electrodes depends on the properties of the material being modified. Partition of one zone of high-power corona discharge into several zones of lower power prevents thermal damage of the material and makes the modification much more uniform. Use of the five-tip discharge electrodes still increases the modification uniformity. The tests of the new corona treatment unit showed that it worked correctly and enabled to modify textile polyester materials properly. Deposition of an aerosol onto the material being modified and carrying out the corona treatment process in various gases are other essential features of the new equipment set. This creates new perspectives for development of the techniques for modification of the surface layer of different textile polymer materials.
