Sažetak
The purpose of this research was to analyse the influence of a plasma treatment on the surface properties of cellulose-based knitwear, especially on the hydrophilicity of raw cotton material. The influence of oxygen and argon low-pressure plasma pre-treatment was analysed from the aspect of antimicrobial properties as well as in the context of applying digital ink jet printing technique, researching the interaction and mutual impact of these two approaches. Colour spectral parameters of printed textile surfaces were explored and described, as well as the characteristics of colour yield. The effectiveness of antimicrobial treatment conducted by deposition of silver nanoparticles on plasma-activated surface was investigated. It is certain that plasma pre- treatment increases the hydrophilic properties of textile materials and impacts the colour spectral parameters of printed area. An increase in the colour yield and fastness, as well as handle of ink jet printed samples was observed on plasma pre-treated sample materials. Antimicrobial analyses showed that the silver nanoparticles, as active compounds of antimicrobial agent, were partially blocked with polymer, which contributed to limiting effect of antimicrobial effectiveness, while the printed area of the sample exhibited better antimicrobial protection and visible inhibition zone was observed.
