| Abstract: | This study aimed to obtain functional viscose textiles based on chitosan coatings with
improved antibacterial properties and washing durability. For that reason, before functionalization
with chitosan/zinc nanoparticles (NCH+Zn), the viscose fabric was modified by nonthermal gas
plasma of dielectric barrier discharge (DBD) to introduce into its structure functional groups suitable
for attachment of NCH+Zn. NCH+Zn were characterized by measurements of hydrodynamic diameter and zeta potential and AFM. DBD-plasma-modified and NCH+Zn-functionalized fabrics were
characterized by zeta potential measurements, ATR-FTIR spectroscopy, the calcium acetate method
(determination of content of carboxyl and aldehyde groups), SEM, breaking-strength measurements,
elemental analysis, and ICP-OES. Their antibacterial activity was determined under dynamic contact
conditions. In addition to SEM, the NCH+Zn distributions on viscose fabrics were also indirectly characterized by measuring their absorbent capacities before and after functionalization with NCH+Zn.
Washing durability was monitored through changes in the zeta potential, chitosan and zinc content,
and antibacterial activity after 1, 3, and 5 washing cycles. The obtained results showed that DBD
plasma modification contributed to the simultaneous improvement of NCH+Zn sorption and antibacterial properties of the viscose fabric functionalized with NCH+Zn, and its washing durability,
making it suitable for the production of high-value-added medical textiles. |
