Highly Antibacterial and Antifungal Cotton Fabric for Effective Odor Adsorption and Durable Waterproofing.

The demand for antibacterial, antifungal, and deodorant textiles has grown significantly with the increasing concern for health and hygiene. In this study, novel functional cotton fabric (EE) with long-lasting antibacterial, antifungal, and deodorant activity was prepared by graft modification with triclosan and eugenol. EE shows more than 99% antibacterial and antifungal activity against Staphylococcus aureus, Escherichia coli, Candida albicans, and Trichophyton rubrum through mechanisms such as inhibiting enzyme activity and disrupting cell structure. In addition, EE shows a deodorization rate of more than 70% for odorous gases produced by humans, such as sweat, foot odor, and manure odor. In contrast to conventional coatings or wraps, EE demonstrates long-lasting and stable functionality. After 50 washing cycles, EE still exhibited durable antibacterial and antifungal properties that exceeded the AAA requirements (FZ/T 73023, showing a 99% antibacterial and antifungal rate after 50 washes) and excellent deodorant properties. While retaining the breathability and biosafety of the original cotton fabric, EE also possesses antifouling properties. Therefore, the development of cotton fabric with long-lasting antibacterial, antifungal, and deodorant functions in this study addresses the urgent need for public health and environmental friendliness. The EE can effectively enhance the value of textiles and the quality of life for users.
