Abstract
The presented study introduces an approach for coating to realize antimicrobial textile surfaces without the use of nanoscaled metal particles. Bactericidal metal ions were used instead of elementary metal particles and stored in alginates, which were fixed on the textile substrate by a coating application. A newly developed coating process for fixation was conducted which was derived from a polyester dyeing process leading to a significantly higher antimicrobial activity than the application of a common sol–gel coating. For this purpose, a specific coating agent was developed. Antimicrobial testing was done by a viability assay against Escherichia coli and Staphylococcus aureus. The promising results in antibacterial activity could probably in the future lead to useful coating applications for textiles as well as for other polymeric substrates.
