Synthesis and Application of Isothiazolinone as Durable Antibacterial
A new antibacterial with two reactive groups was synthesized from isothiazolin-3-one and characterized by 1H-NMR and ESI-MS. Through the orthogonal experiments the optimal finishing process was got, that was bath ratio 1:20, Na2SO4 20 g/L, NaHCO315 g/L, T1:60°C, T2:70°C, t1:10 min, t2:20 min, t3:30 min (as shown in fig.1). The antibacterial evaluations of treated cotton fabrics showed that the antibacterial rates for Escherichia coli and Staphyloccocus aureus were 95.64% and 97.83% respectively, and 88.13% and 90.05% respectively after 30 washing cycles. The results indicated that the treated fabric had excellent antibacterial performance and washing durability.
