Abstract

Nanosuspension of prodigiosins micelles produced by the fermentation of Serratia marcescens was utilized as a novel kind of cleaner disperse dye for polyester fabric dyeing. The average particle size of the pigments dispersion was 184.3 nm (range of 101.1–378.0 nm). The effects of technical parameters including dyeing temperature, dyeing time and dye bath pH on dyeing effects, antibacterial and ultraviolet protective properties of dyed fabrics were explored. The results indicated that when the dyeing temperature was set at 110 °C with a holding time of 30 min, dyed polyester under dye bath pH of 1.9 and 7.9 possessed high color strength, outstanding bacteriostatic rate of above 89.0% against Staphylococcus aureus and very good UV-protection ability. In addition, the dyed fabrics exhibited excellent rubbing, washing and perspiration color fastness but poor light color fastness. This research developed a novel clean method of preparing prodigiosins disperse dye by microbial fermentation and dyed polyester fabric to endow it with functionalities.
