The antibacterial activity of the textile fabrics coated with
different silver ratios is seen in Tables 3 and 4 against E. coli and
S. aureus, respectively. Tables 3 and 4 show both the change in
antibacterial activity by increasing silver precursor ratio in the firstrow, and the effect of coating with silver nanoparticles on
antibacterial activity as well as the laundry performance of antibacterial
activity for 30:1 ratio in the second row, against E. coli
and S. aureus, respectively. The clear zones in the areas surrounding
the surface of textile fabrics were observed, while there is no
antibacterial activity around the bare fabrics, Tables 3 and 4. It is
clear that the antibacterial activity is higher against E. coli than S.
aureus for all ratios since there is a wider inhibition zone around
the fabric. To test the permanency of antibacterial activity, the fabric
was washed in an ordinary washing machine using ordinary
detergent. It was observed to decrease the antibacterial activity
against E. coli after the third washing for 10:1 and 20:1 ratios,
whereas the fabric samples with 30:1 ratio still had antibacterial
activity up to five washings.
