Sažetak
The research presented describes the impact of the gases used in plasma treatments on some mechanical properties of cellulosic fabrics defined structural characteristics. Oxygen (O2) and Argon (Ar) as non-polymerizing working gases were used in the experiments. In preliminary researches process parameters of plasma treatment were optimized in order to functionalize the fiber surface and to achieve a target alteration of the cellulose fabrics properties. The processes are complex, and the final effects depend on many factors ; type of material, plasma type, plasma parameters and treatment conditions. Plasma treatments were carried out using a low-frequency plasma system of 40 kHz under optimised process conditions: gas flowrate of 40 cm3/min, pressure of 0.3 mbar, power of 300 W, and treatment time of 5 min. Fabrics of cotton, lyocell and modal fibers of approximately equally structural characteristics were used for plasma treatments. Mechanical properties - breaking force and breaking elongation were tested, according to HRN EN ISO 13934-1:2008, while the bending rigidity was tested using standardized method according to HRN EN ISO 9073-7:2003. The experimental results provide data which indicate on increased of breaking force after plasma treatments of cotton fabrics, in relation to the regenerated cellulose fabrics (lyocell and modal) where the lower reduction of breaking force is evident. Bending rigidity of tested fabric samples indicate on the similar effect, but results are non-uniform.
