“…31 The energy consumption of the new method, which is calculated based on the absorbed dose and energy utilization rate of the electron accelerator device, is 75 kJ/kg, while traditional dyeing reaches 6083 kJ/kg. 32 In addition, traditional dyeing with reactive dyes is accompanied by a large amount of dye hydrolysis, and hydrolyzed dyes adhere to the surface of cotton fabric need to be washed at least 3 times. 33 However, the dyeing via E-Beam irradiation has a high dye utilization rate, and grafted cotton fabric only needs to be washed once.…”

Traditional dyeing processes of the textile industry have to use a lot of dyeing assistants and water, resulting in massive lower-biodegradable wastewater and causing great environmental pressure. In this study, we developed a green textile dyeing route featuring high dyeing efficiency and low effluent by using electron beam (E-Beam) irradiation to trigger cotton fabric dyeing with custom-tailored reactive dyes. In which, three vinyl-containing reactive dyes with primary colors were first synthesized and then covalently bonded to cotton fibers via graft copolymerization. The color of the fabric can be facilely tuned by adjusting the ratios of the custom-tailored dyes, which achieved high brilliancy, rich hues, and excellent wash-fastness. Different from the traditional dyeing process, the E-Beam irradiation-induced dyeing process was performed successfully with no requirement to salt, alkali, or heat conditions. Moreover, the utilization of all three dyes was nearly 100% in the E-Beam irradiation-induced dyeing process. Also, almost no residual dyes were washed off from the dyed cotton fabric during the washing process; thus, the spent washing stream exhibited so clean that it completely met the requirements of the zero discharge of hazardous chemical program. This study demonstrated that here E-Beam irradiation-induced dyeing on cotton fabric is a novel green textile dyeing route with energy-saving and pollution-free features, which is beneficial to the transformation to green and sustainable development of the traditional textile industry.

Manganese dioxide nanomaterials with high crystallinity and purity was prepared quickly by a simple hydrothermal reaction, and the effect of hexadecyl trimethyl ammonium chloride (CTAC) on crystal form, morphology and pore structure of manganese dioxide was investigated. Removal of methylene blue from aqueous solution by adsorption onto two manganese dioxide adsorbents was studied. The material characterization results showed that manganese dioxides have (2×2) tunnel structure and nanowires morphology. BET surface area and pore volume of ɑ‐MnO2 (CTAC) was 58.99 m2/g and 0.2081 cm3/g, respectively. The adsorption results showed that pH value had a certain effect on the removal of methylene blue. The adsorption kinetics results indicated that the adsorption rate of ɑ‐MnO2 and ɑ‐MnO2 (CTAC) to methylene blue was very fast, most adsorption was completed within 5 minutes, and the adsorption equilibrium was reached after 2 hours. The removal efficiency of ɑ‐MnO2 and ɑ‐MnO2 (CTAC) was 71.27 % and 78.92 %, respectively. Pseudo‐second‐order kinetic model was better fitted with adsorption data than pseudo‐first‐order model, suggesting adsorption behavior is controlled by chemical processes. Additionally, the free energy change (ΔGΘ) was determined by Van′t Hoff equation is negative, which confirms the adsorption process is spontaneous and feasible. The adsorption mechanism involves a complex process of electrostatic attraction, charge‐independent adsorption, physical adsorption, hydrogen bonding and redox.

“…12 However, there are still some problems to be resolved in terms of waterwaste post-treatment in the practical application of alkaliclearable dyes. 13 In addition to adopting ecological post-treatment clearing methods to reduce the use of reducing agents (alkali-clearing instead of reduction clearing), some sustainable issues are also related to the properties of the dye itself and the interaction force of the dye with the fiber. [14][15][16] Dyes with poor fastness may be discharged into water resources due to weak adsorption of dyes to fiber surfaces under washing or external force.…”

Dye wastewater has attracted great attention due to high pollution and toxicity which can cause harm to the living environment. It is common for azo-disperse dyes to be used to dye hydrophobic fibers. A reduction clearing method is used to eliminate the dye particles on the fabric after dyeing. However, when azo disperse dyes on the fiber surface are eliminated by the reduction clearing process, this can give rise to an effluent discharge due to the presence of sodium hydrosulfite. The introduction of carboxylic ester groups into dye molecules can effectively avoid this issue. Six novel environmentally friendly alkali-clearable disperse dyes, containing cyano and carboxylic ester groups, were readily synthesized by a diazo coupling reaction with various diazo components. Their dyeing properties on polyethylene terephthalate fabrics were respectively measured and compared with those of commercial reference dyes. It was indicated that some fastness properties of the synthesized dyes on polyethylene terephthalate fabrics after the alkali clearing were improved compared with those of the reference dyes due to the existence of the carboxylic ester group. Moreover, the chromaticity of dye wastewater can be further reduced by recovering hydrolyzed dyes.
