摘要：
In order to improve the moisture absorption, dyeing and antibacterial properties of flame retardant polyester fabrics, polymer coatings with different molecular weights, including poly (2 - (methacryloyloxy) ethyl) dimethyl - (3 - sulfopropyl) ammonium hydroxide (PSBMA), poly (2 - (methacryloyloxy) ethyl) trimethylammonium chloride solution (PMTAC) and their block copolymer PSBMA-b-PMTAC, were grafted separately on the surface of flame retardant polyethylene terephthalate (FRPET) fabrics via polydopamine mediated surface initiated atom transfer radical polymerization (SI-ATRP) technology. The surface morphology, water absorption, moisture permeability, air permeability, dyeing, bacteriostatic and flame retardant properties of these surface modified FRPET fabrics were characterized and tested to study the changes of flame retardancy, moisture permeability, bacteriostatic and dyeing properties of FRPET after surface modification. The results indicated that the peak heat release rate of block copolymer PSBMA - b- PMTAC modified FRPET fabrics reduced 60.7% comparing to that of FRPET. Compared with pristine FRPET, the modified polyester fabric showed higher water absorption and satisfied the standard of woven hygroscopic products. In addition, the modified fabrics with cationic dyeing possess certain bacteriostatic performance and the bacteriostatic rate of Escherichia coli was increased by 27%. © 2022 China Textile Engineering Society.
