Two low-pressure ultraviolet (UV) lamps at 185/254 nm with sodium persulfate in a pilot UV device were utilized for the degradation of reactive red (B-3BF) dye wastewater compared with two UV lamps at 185/185 nm and two UV lamps at 254/254 nm. The degradation performances of UV irradiation (254/185 nm) with sodium persulfate under different degradation times, flow rates, initial pH, initial Na2S2O8 concentrations and initial dye concentrations were investigated. The experimental results illustrated that the degradation percentage of B-3BF dye could reduce to 90.42% with the energy consumption of 85.1 kWh/kg and the residual dye concentration of 1.92 mg/L by UV irradiation (254/185 nm) with initial Na2S2O8 concentration of 1.5 mmol/L and initial dye concentration of 20 mg/L. In addition, degradation performance of B-3BF dye wastewater by UV irradiation (254/185 nm) with sodium persulfate was more effective than those of UV irradiation (254/254 nm) and UV irradiation (185/185 nm). Therefore UV irradiation (254/185 nm) with sodium persulfate was promising for the degradation of B-3BF dye wastewater.

The growing demand for innovative routes to develop functional textiles initiated the necessity of new efficient functional molecules. Dyes can provide durable functional protection to textiles due to their ability to generate strong dye–fiber interaction. New dyes to improve a dyed substrate’s quality and aesthetic appearance are in huge demand. This research aims to prepare a mosquito-repellent and UV-protective acrylic fabric using a novel cationic (basic) dye. The cationic dye was synthesized and thoroughly characterized with the help of FTIR, 1H NMR, 13C NMR, and CHN analysis. The dye was further used for the dyeing of the acrylic fabric by using an infrared dyeing machine. To analyze the suitability of dyed fabrics for daily use, washing, rubbing, and light fastness of dyed fabrics were determined. The amount of dye (%) taken up by the acrylic fabric (exhaustion %) was determined, and more than 72% of exhaustion was obtained. The fixation (%) of the dye on acrylic fabrics was also quantified, and more than 80% fixation was obtained. The coloration properties of the dyed fabrics (L*, a*, b*, and K/S) were examined. The dyed fabrics showed a K/S of more than 3. The mosquito-repellent action provided by the dyed fabrics was also analyzed, and 100% repellency was obtained. The dyed fabrics provided an excellent UV-protective property. The multifunctional properties of dyed fabrics were retained significantly even after laundering treatments. The dyed fabrics were characterized using X-ray diffraction and thermogravimetric analysis. A reduction in crystalline peak intensity after dyeing was obtained. The dyed and undyed fabrics were also tested for their tensile strength.
