Photosynthesis of Carboxymethyl Starch-Stabilized Silver Nanoparticles and Utilization to Impart Antibacterial Finishing for Wool and Acrylic Fabrics

Table 1

Effect of irradiation time on the durability of the antibacterial finished acrylic fabric. Finishing conditions: padding for 1 h, drying at 60°C for 15 min. Curing conditions: UV curing for 15, 30, and 60 min. Washing conditions: 5 g/L nonionic detergent and 2 g/L sodium carbonate using a fabric: liquor ratio of 1 : 50 at 45°C for 15 min., rinsing twice in 100 mL water.
