Sažetak
In order to carried out the targeted modification of properties and achieve the desired effects by plasma treatment, it is necessary to determine and optimize the processing parameters such as the type of gas, gas flow rate, operating frequency, current, voltage, treatment time and distance between the electrodes and the substrate surface. In this paper the plasma device designed for treatment of spun yarns from lyocell fibers is applied, by varying the velocity i.e. time of the passage of yarn through the glass coil inside of which is created an argon plasma for uniform yarn treatment at atmospheric pressure. The effect of the plasma is determined by testing the physical properties - unevenness and hairiness, and part of the mechanical properties - breaking force and elongation. Results indicate that argon plasma acting to modification of physical properties of tested yarns but for optimizing of the process parameters it is necessary to carry out more treatments under various conditions. According to obtained results of tested physical properties, the changes are mainly reflected in the reduction of yarn hairiness and unevenness. Argon plasma at different time and velocity does not significantly affect on the distortion of the mechanical properties expressed through breaking force and elongation, and tensile strength of tested yarns.
