TL;DR
Viscose fabric was made antibacterial and antioxidant using pomegranate peel extract and chitosan, with properties lasting through multiple washes.
Contribution
A new eco-friendly method to functionalize viscose fabric using pomegranate peel extract and chitosan is introduced.
Findings
Functionalized fabric showed 100% bacterial reduction against Staphylococcus aureus after five washes.
Antioxidant activity was 70.5% and 60.1% for pre-oxidized fabrics after 60 and 120 minutes, respectively.
Color stability was maintained after five washing cycles.
Abstract
Given the increasingly stringent environmental standards mandated today, the functionalization of textile materials using natural biopolymers and plant extracts represents an environmentally acceptable alternative to traditional synthetic agents. To obtain functionalized viscose fabric, a pretreatment process involving periodate oxidation followed by chitosan deposition was performed. Chitosan provides enhanced biological properties due to the presence of amino groups, which enable its deposition and the application of pomegranate peel (Punica granatum L.) extract during functionalization. Pomegranate peel extract contains a large number of bioactive compounds that further enhance the antibacterial and antioxidant activities of the functionalized viscose fabric. Changes in surface chemistry, morphology, and biological properties after functionalization and up to five washing cycles were…
