Bioactive Textiles Obtained by Using Aqueous Extracts of Vine Leaves

The vine leaves are an abundant by-product which is not fully valorized. This study reports the application of vineleaves, as a natural resource of dyes and chelating agents, in the sustainable process of dyeing and antibacterial treating of theviscose fabric. In order to increase the color intensity and to confer antibacterial properties to the textile materials, the dyedviscose fabric was treated with zinc acetate (by a post-mordanting procedure). The main quality indices of the aqueousextract of vine leaves (pH, density, acidity, and peroxide indices) and the total content of polyphenols and flavonoids weredetermined. The functional groups of the constituents from the aqueous extract fixed on the viscose fiber surface by dyeinghave been highlighted by FTIR analysis. The presence of zinc onto viscose fabric due to its chelating with the hydroxylgroups and carbonyl groups from polyphenols, flavonoids, and cellulosic species was confirmed by FTIR and EDX analysis. The antimicrobial activity of viscose samples dyed and treated with zinc acetate was evaluated against E. coli and St. aureusbacteria. The color fastness to washing, perspiration, and rubbing of dyed fabric samples was determined and evaluatedaccording to SR EN ISO standards.
