Sažetak
Research related to the plasmas application are particularly actual in the development of ecological processing of textile materials with the purpose of obtaining materials required functional properties. The targeted modification of the properties was achieved by plasma acting at the surface of textile material, due to the different physical and chemical processes occurring in the interaction plasma and textile surface. More recent research application of plasma in the area of textile materials are focused on the development plasma as the physical medium for the direct application of various agents and particles for the modification the properties of the treated surface of the textile material. A particular challenge is achieving of multifunctional protective properties with the more economical and environmentally friendly processes conducted directly in plasma. This paper will present some results of surface modification of lyocell fabric after pretreatment plasma with oxygen, and after treatment using the carboxylic acid (acrylic acid) and silver chloride processes in the plasma, analyzed by scanning electron microscopy (SEM). Effect of plasma treatment on the chemical properties of the textile substrate using XPS and FTIR-ATR techniques were analyzed. All treatments were conducted on cellulose lyocell fabric of defined structural characteristics, using the low-pressure plasma LF-40kHz, under optimized process parameters. Results indicate to plasma acting on the surface of the tested fabric, creating morphological changes into the form of light etching, which becomes accessible for better binding of various chemicals and achieve of the targeted modifications. Particularly significant is oxygen plasma treatments, which chemically and physically change the surface properties of the fabric, and enables a better binding of carboxylic acids deposited by PE-CVD process. XPS analysis results confirm such findings. It should be emphasized that such actions do not disturb the bulk properties of the fabric, and the procedures are carried out in dry, closed and environmentally reliable systems.
