Subject content

Classification of the plasmas (differences of natural and laboratory plasma – depending about pressure: low-pressure, atmospheric - corona discharge, dielectric barrier discharge, glow discharge and plasma jet). Plasma phenomena in nature. Mechanisms of plasma generation and plasma acting depending about parameters - frequency of generators (MF, RF, LF), working pressure, power, gases and treatment time. Basic processes - ionization and recombination processes (in respect to weak and highly ionized plasma, ie thermodynamic equilibrium, types of collisions between charged (electron) and neutral particles in plasma). Specific and complex plasma-chemical reactions as a result of collision of plasma particles and interaction with the contact surface. Application of such reactions to the research and understanding of specific reactions generated by the interaction of plasma- textile surface that have not yet been fully explored. Major effects of plasma to substrates, depending on the plasma mode and process gases used – fine surface cleaning, activation, surface etching, functionalization, graft – polymerization, cross and coating deposition (polymerization). Plasma diagnostic – different diagnostic tools can be used, depending on the type of plasma under investigation and specific requirements – driving current and voltage waveforms, electrical probing, mass spectrometry and optical emission spectroscopy (application of OES devices and actinometry) etc. Low-pressure vacuum plasma technology – specificity and applicability depending on system characteristics and treatment substrate specificity. Evaluating and assessment of achieved effects by sophisticated methods of surface analysis and obtained properties. Specificity of atmospheric plasma technology and application in the treatment of textile materials and analysis of obtained properties by sophisticated methods. Economic and ecological viability of the implementation of low-pressure or atmospheric plasma systems in production processes with the aim of modernizing technological processes and creating textiles / products added value regarding of its developing the competitiveness of domestic and world markets.

Aim of course

Theoretical knowledge about the possibilities of applying new plasma technologies in the modification of textile materials. Practical knowledge in the work with low-pressure and atmospheric plasma systems for targeted treatments of textile materials. Competence and ability of independent action by applying low-temperature plasmas technology in textile and other industries.
