One-Pot Preparation of a Novel Imidazole-Containing Water Polyurethane to Improve the Discoloration and Durability of Silver Ion Antimicrobial Finishes on Light-Colored Cotton Fabrics
This study introduces a new silver-based antibacterial coating for white cotton fabric, overcoming the discoloration and durability limitations of traditional silver ion agents. A one-pot hydrothermal synthesis created a waterborne polyurethane (WPU) resin with imidazole groups. Combining this WPU resin with a silver ammonia solution and applying it to cotton fabric resulted in a functionalized textile with superior whiteness retention and lasting antibacterial properties. After 8 h of simulated sunlight, the whiteness of the treated fabric (76.8%) showed a significant improvement of 30.6% compared to a similar treatment without imidazole (58.8%), and even surpassed that of the untreated fabric (76.5%). Furthermore, the fabric maintained 99.9% inhibition rates against E. coli and S. aureus after 20 washes, with no adverse effects on other performance characteristics. This innovative approach enables the large-scale production of silver-coated antibacterial agents suitable for light-colored cotton textiles.
