Abstract—This paper focuses on the effects of plasma treatment applied to the rechargeable antimicrobial finishing for cotton fabrics. Nitrogen plasma treatment was used in the traditional pad-dry-cure finishing process of cotton fabric coated with 5, 5-dimethylhydantoin (DMH) with the aim of enhancing the coating effect and antimicrobial property. Then chlorine was introduced into nitrogen-containing groups on the coated cotton fabrics in order to make it antimicrobial by chlorination with sodium hypochlorite. FTIR was used to evaluate the surface properties, including the existence of DMH on cotton fabric and the content of DMH on cotton fabric after modification. The results showed that nitrogen-plasma introduces nitrogen-containing groups into cotton fabrics, the coating effect and adhesion of DMH on cotton fabric was enhanced with nitrogen plasma treatment, the successful introduction of chlorine on the coated fabric inhibits bacteria,
S. aureus, effectively and the antimicrobial property is rechargeable.
