Biogenic silver nano sol–loaded spunlace fabric for wound dressing; mechanical and functional characterization

Abstract

The biogenic silver nano sol (AgNS) is most suitable for biomedical applications due to its inherent properties. In the present investigation polyester (P), viscose (V) and polyester/viscose blend (50:50) (PV) spunlaced fabrics were coated with AgNS prepared using organic honey, manuka honey. The dip-coated fabric samples were found suitable for wound dressing purposes when evaluated layered wise for their mechanical properties. The layer-wise dispersion behavior of the V sample was found better than the P/V and P samples. In the case of the air permeability sample, P/V performed better compared to V and P samples. Water sorption ability of P/V and V are found suitable for wound dressing. The ultraviolet protection factor value of treated fabric found excellent when coated with only honey. Further, the AgNS loaded fabric exhibited good resistance against microbial organisms as revealed by the bromophenol blue stain.
