| Abstract: |
| This paper is mainly focused on introducing cotton composite fabric with hydrogel and antimicrobial properties using corn silk (Zea mays L) as a natural polymer having hydrogel properties. Corn silk is rich in phenolic compounds, particularly flavonoids. It also consists of proteins, vitamins, carbohydrates, calcium, potassium, magnesium and sodium salts, volatiles oils and steroids such as sitosterol and stigmasterol, alkaloids, and saponins. In-situ synthesis of copper on cotton fabric was carried out along with using corn silk solution that was prepared from dried corn silk dispersed in alkali media of sodium hydroxide and urea. Copper acetate as copper precursor and ascorbic acid as ecofriendly reducing agent were added to the alkali solution of dispersed corn silk to in-situ synthesis copper nanoparticles on the cotton fabric. The water absorption behavior of the treated fabrics was investigated with moisture regain, water retention, drying time of wetted fabric at room condition and vertical wicking. Antibacterial properties of the samples were also evaluated against Escherichia coli and Staphylococcous aureus. The SEM pictures confirmed formation of nano copper and hydrogel layer on the fabric surface and XRD performed the crystal and particle size of the nano copper. The treated cotton fabrics showed good water absorption properties along with reasonable antibacterial effectiveness. |
