  Abstract

The vine leaves are an abundant by-product which is not fully valorized. This study reports the application of vine leaves, as a natural resource of dyes and chelating agents, in the sustainable process of dyeing and antibacterial treating of the viscose fabric. In order to increase the color intensity and to confer antibacterial properties to the textile materials, the dyed viscose fabric was treated with zinc acetate (by a post-mordanting procedure). The main quality indices of the aqueous extract of vine leaves (pH, density, acidity, and peroxide indices) and the total content of polyphenols and flavonoids were determined. The functional groups of the constituents from the aqueous extract fixed on the viscose fiber surface by dyeing have been highlighted by FTIR analysis. The presence of zinc onto viscose fabric due to its chelating with the hydroxyl groups 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. aureus bacteria. The color fastness to washing, perspiration, and rubbing of dyed fabric samples was determined and evaluated according to SR EN ISO standards.
