“…The diameter of the filaments was 17 ± 3 µm, at a draw ratio of 3:1. It is considered that the proportion between the core/shell remains in a similar proportion after the drawing process, which would still confine more to the CuNP in the shell of each filament since their thickness decreases proportionally [24][25][26][27]. Morphology and elemental analysis by SEM.…”

“…Elemental analysis was implemented in two specific zones near the surface of the filament, identified with the numbers 1 and 2 which correspond with the EDS analysis, as shown in Figure 4C. In both zones, a Cu signal appears, and this could be related to the confinement of the CuNP during the bi-component fiber forming, wherein the PET/CuNP nanocomposite was placed in the shell of the filament [24,26]. Morphology and elemental analysis by SEM.…”

In this study, textile fiber prototypes based on polyester and different Cu nanoparticles (CuNP) content were produced using melt-spinning to obtain bi-component multifilament fibers and melt-blowing to obtain non-woven fabrics. The prototypes were tested against pathogenic microorganisms such as S. aureus, E. coli, and C. albicans. It was shown that bi-component fibers offer excellent protection against pathogens, with up to 99% growth inhibition with 0.5% w/w for S. aureus and E. coli; meanwhile, non-woven fabric only shows activity against E. coli from 0.1% w/w of CuNP. Using different analytical techniques, it was possible to identify that the CuNP were confined exclusively in the outer cover of the bi-component fibers which may be associated with increased antimicrobial activity compared to the fibers in the non-woven fabric. The use of polymeric nanocomposites based on polyester/copper offers an alternative of great interest due to the versatility of the raw material and the high efficiency of copper nanoparticles as an antimicrobial additive.
