Abstract: This research explores the dyeing of cotton fabric using lignin, a by-product of the paper industry, combined with surface modification using glyoxal and sericin, a protein-based substance from silk degumming. The purpose of the surface modification process is to introduce positively charged functional groups onto the cotton fabric to enhance its adhesion to negatively charged lignin. Silver nanoparticles were also synthesized and incorporated into the dyeing process using the exhaustion method to impart additional functional properties. Post-dyeing, the cotton’s chemical characteristics were analyzed using Fourier Transform Infrared Spectroscopy (FTIR), and its morphological properties were examined with an optical microscope (OM). The study further evaluated antibacterial activity, UV protection, and textile-specific attributes, including CIE Lab* color parameters and color strength (K/S). The findings revealed that surface-modified cotton improved dye adhesion with lignin and silver nanoparticles, producing colors ranging from yellow to brown. The color strength (K/S) increased with higher glyoxal concentrations. Additionally, the cotton fabric dyed with lignin demonstrated antibacterial activity against Staphylococcus aureus.
