Synthesis and Application of a Reactive Water-soluble Antibacterial

A new reactive water-soluble isothiazolinone antibacterial was synthesized and characterized by H-1-NMR and ESI-MS. Through the orthogonal experiments, the optimal finishing process for cotton fabric was got, that was the bath ratio 1:20, Na2SO4 20 g/L, NaHCO3 15 g/L, t(1): 30 min, t(2): 50 min, T-1: 50 degrees C, T-2: 95 degrees C. The antibacterial evaluations of treated cotton fabrics showed that the antibacterial rate for S. aureus was 92.92%, and 86.04% after 50 washing cycles. The results indicated that the treated fabric had excellent antibacterial performance and washing durability.
