Abstract:
Linen fabrics are printed on a screen printing semi-automatic machine S-300. The printing is done with a modified alginate pasta with addition of Pinus sylvestris L. alcohol extract and zinc oxide. The antimicrobial activity of printed linen fabrics against Escherichia coli, Staphylococcus aureus and Candida albicans are examined. Antimicrobial activity against S. aureus is observed in samples printed with alginate pasta modified with Pinus sylvestris L. Electrical conductivity is measured using a HAMEG LCR bridge in the frequency range from 24 Hz to 125 kHz at room temperature. The main result of this study is that the addition of zinc oxide to the alginate paste of printed linen fabrics shows an increase in the electrical conductivity as well as antimicrobial activity against S. aureus.
