Pre-loading of monochlorotriazinyl β-Cyclodextrin (MCT-βCD) onto/within viscose/wool (V/W) and cotton/wool
(C/W) blended fabrics provide hosting cavities that can form host-guest inclusion complexes with reactive dyes in postprinting
as well as with triclosan derivative or silver nanoparticles/hyperbranched polyamide-amine (AgNPs/HBPAA)
composite in subsequent final antibacterial finishing step. Coloration properties, antibacterial activity against (S. aureus) and
(E. coli) pathogenic bacteria, durability of the obtained products, according to the above mentioned route, to wash, surface
morphology and composition of selected samples were investigated. Results obtained signify that premodification of the
nominated substrates with MCT- βCD (10 g/l), followed by reactive printing with mono-or bifunctional reactive dye (20 g/l),
and subsequent post-finishing with triclosan derivative or AgNPs/HBPAA composite (15 g/l each) is an efficient treatments
sequence for attaining reactive prints with significant antibacterial efficacy and noticeable durability to wash. Surface
depositions of selected active ingredients were also confirmed using SEM and EDX analysis. |
