Liang He,Chang Gao,Sha Li,Cordelia T.W. Chung,John H. Xin 한국공업화학회 2017 Journal of Industrial and Engineering Chemistry Vol.46 No.-
An antibacterialfinishing protocol using a reactive sulfobetaine was reported to fabricate safe anddurable antibacterial textiles. The specifically designed sulfobetaine contains highly reactive triazinegroup acting as an anchor tofix the antibacterial betaine group on textiles via covalent bond formation. After thefinishing, the textiles were endowed durable antibacterial activities of 98.0% against gramnegativeEscherichia coli and 95.2% against gram-positive Staphylococcus aureus even after they werelaundered for 30 times. The safety evaluation showed that the reactive sulfobetaine had no skin irritationand cytotoxicity. These results indicate that the developed antibacterialfinishing is safe and durable ontextiles.
