 Full text | Abstract: This paper presents methods for the surface modification of cotton woven fabric and polypropylene non-woven in order to make them antibacterial. In the case of cotton fabric, its surface was functionalised with chloroacetate groups by means of chloroacetyl chloride, using pyridine as a catalyst, followed by the quaternalisation of the chloroacetate groups with poly(4-vinylpyridine). In the second process polypropylene nonwoven was impregnated with a multimonomer containing vinyl groups, which were then changed into tertiary amine groups by the addition of diethylamine. These groups were quaternalised with propyl bromide. In the next method colloidal silver was incorporated into the nanolayers formed from polyelectrolytes on the polypropylene non-woven. Quantitative tests of bacteriological activity of the modified woven fabric and non-woven showed both bacteriostatic and bactericidal activities in relation to Escherichia coli. In addition, colloidal platinum was incorporated into previously deposited polyelectrolyte nanolayers in order to impart catalytic properties to fibers. The results obtained clearly show the catalytic action of such systems, the oxygen release from the hydrogen peroxide solution being an example. |
