Eco-Friendly Disperse Dyeing of Ultraviolet-Treated Polyester Fabric Using Disperse Yellow 211

3-(dimethylamino)-1-phenylprop-2-en-1-ones were obtained with good yields by reacting dimethylformamide dimethylacetal with different methyl ketones. 3-oxo-3-phenyl-2-(2-phenylhydrazono)propanals disperse dyes were obtained via reacting of 3-(dimethylamino)-1-phenylprop-2-en-1-ones with phenyldiazonium chloride. The novel dyes were used in dyeing polyester fabrics through two different dyeing methods at temperatures of 100 and 130 °C. We found that the color strength when using the dyeing method at 130 °C was better than the dyeing method at 100 °C. The fastness properties of dyed fabrics with these new disperse dyes were studied and gave very good results (except for fastness to light, which gave moderate results). The new dyes were evaluated against some different types of bacteria and cancer, which showed excellent and promising results for the possibility of using these dyes as antibacterial and anticancer agents.

“…We have recently utilized ultrasound energy to improve the dyeing of polyester fabrics when dyeing with disperse dyes [3]. One of the environmentally friendly advantages of using microwave energy is rapid heating to high temperatures allowing greater ease of reactions, because the increased frequency of molecular vibrations during microwave irradiation speeds up these reactions [4][5][6][7][8][9][10][11][12][13][14]. Enaminones, pyridone, and pyrazolopyrimidines are key intermediates in the preparation of dispersion dyes due to their low cost and excellent antimicrobial activity.…”

In this review, we present preparation methods for a series of new disperse dyes that we have synthesized over the past thirteen years in an environmentally safe and economical way using innovative methods, conventional methods, or using microwave technology as a safe and uniform method of heating. The results showed that in many of the synthetic reactions we carried out, the use of the microwave strategy provides us with the product in minutes and with higher productivity compared to the conventional methods. This strategy provides or may dispense with the use of harmful organic solvents. As an environmentally friendly approach, we used microwave technology in dyeing polyester fabrics at 130 degrees Celsius, and then, we also introduced ultrasound technology in dyeing polyester fabrics at 80 degrees Celsius as an alternative to dyeing methods at the boiling point of water. Here, the goal was not only to save energy, but also to obtain a color depth higher than the color depth that can be obtained by traditional dyeing methods. It is worth noting that obtaining a higher color depth and using less energy means that the amount of dye remaining in the dyeing bath is less, which facilitates the processing of dyeing baths and therefore does not cause harm to the environment. It is necessary after obtaining dyed polyester fabrics to show their fastness properties, so we explained that these dyes have high fastness properties. The next thought was to use nano-metal oxides to treat polyester fabrics in order to provide these fabrics with important properties. Therefore, we present the strategy for treating polyester fabrics with titanium dioxide nano-particles (TiO2 NPs) or zinc oxide nano-particles (ZnO NPs) in order to enhance their anti-microbial properties, increase their UV protection, increase their light fastness, and enhance their self-cleaning properties. We reviewed the biological activity of all of the newly prepared dyes and showed that most of these dyes possess strong biological activity.

“…It is worth noting that heterogeneous, bright-colored. Azo dyes are widely used for dyeing polyester [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. Polyester is one of the polymers containing ester bonds obtained from the polycondensation reaction of diol and dicarboxylic acid ( Figure 1 ) [ 4 ].…”

“…Some recent reports [ 1 , 2 ] have used ultrasound energy to improve the dyeing of polyester fabrics when dyeing with disperse dyes by modifying the surface of the fabric. Additionally, some studies [ 3 ] confirmed that UV rays can be used to improve the color fastness properties without compromising the chemical properties of polyester fabric. One of the environmentally friendly advantages of using microwave energy is the rapid heating to high temperatures that allows for greater ease of reactions, because increasing the frequency of molecular vibrations during microwave irradiation speeds up these reactions as well as reduces the use of solvents [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ].…”

Original work showed the composition of the dyes and the antimicrobial/UV protective properties of a series of dyes obtained in our laboratories over the past twelve years in an easy way using microwave technology and their comparisons with conventional methods. The results we obtained clearly indicated that by using the microwave strategy, we were able to synthesize the new disperse dyes in minutes and with a much higher productivity when compared to the traditional methods, which took a much longer time, sometimes up to hours. We also introduced ultrasonic technology in dyeing polyester fabrics at 80 °C for an environmentally friendly approach, which was an alternative to traditional dyeing methods at 100 °C; we obtained a much higher color depth than traditional dyeing methods reaching 102.9%. We presented both the biological activity of the prepared new dyes and the fastness properties and clearly indicated that these dyes possess biological activity and high fastness properties.We presented through the results that when dyeing polyester fabrics with some selected disperse dyes, the color strength of polyester fabrics dyed at high temperatures was greater than the color strength of polyester fabrics dyed at low temperatures by 144%, 186%, 265% and 309%. Finally, we presented that a ZnO or TiO2 NPs post-dyeing treatment of polyester fabrics is promising strategy for producing polyester fabrics possess multifunction like self-cleaning property, high light fastness, antimicrobial and anti-ultraviolet properties.
