“…This is because irradiation for a short time does not cause any changes on the surface, while for higher exposure time the voids become too open to get diffusion of dye, due to which the dye bath equilibrium may face desorption resulting in low color depth. At optimal exposure time, the surface of polyester fabric is evenly tuned and maximum sorption occurs [11]. But when fabric irradiated for 45 min.…”

Dyes are widely used in the cosmetics, textile, leather, food, paper and plastic industries, but in view of toxicity, these dyes show carcinogenicity towards the environment in the form of effluents [1], due to which the dye bath needs modifications that not only reduce the effluent load but also make the textile processing ecofriendly. Modifications involve the use of modern techniques [2] such as ultraviolet radiation [3], plasma [4], gamma [5-6] ultrasonic, and microwave [7] -all of which make the dyeing process cost-, time-, and laboreffective as well as sustainable. Of these techniques, the role of UV radiation is gaining popularity due to its treatment and efficiency. Previously it has been reported that UV radiation adds value in coloration, as well as improving fastness properties. Due to such wonderful benefits, these rays are used in textiles, wood, fibre, and Pol. AbstractA uniform and eco-friendly heating source, ultraviolet radiation has auspiciously improved the disperse dyeing of polyester fabrics. For our current study we used disperse yellow 211 (DY 211) to dye polyester fabric under the influence of ultraviolet treatment. Both the fabric and dye solution were UV-treated for 15-60 min and dyed under variable conditions. We found that ultraviolet-treated polyester (RP) for 30 min. gives good color strength and darker shades at 70ºC using 70 mL of un-irradiated dye solution (NRS) of pH 8 in the presence of 2% of dispersant. While for the dye bath of pH 11, irradiated polyester (RP) for 45 min. using 90 mL irradiated dye solution (RS) gives good color strength and darker shades at 100°C in the presence of 1% of dispersant. ISO standards for fastness revealed good-to-excellent ratings for different shades dyed under optimal conditions. Ultraviolet treatment not only reduced the time, labor, and money, but also improved color characteristics.

“…Also the ultrasonic rays have open the voids of polyester fabric which alternatively helped to sorb more dye molecules efficiently resulting in good colour strength. The radiation exposure for low time did not activate the surface while for long time exposure have degraded the dye molecules which in turn upon dyeing given low colour depth [27][28]. Thus US treatment for 40 min.…”

IntroductionPolyester is one of the polymers which contain ester linkages formed from poly condensation reaction between dicarboxylic acid and diols [1]. The main reason being the cheap and easily available raw material along with desirable properties such as high strength, light weight and easily dye able, these fibers possess wrinkle resistance as well as good wash and wear properties [2]. It is the most hydrophobic in fiber nature among the common fibers. Due to their compact morphology, its aqueous dyeing required high energy to sorb the disperse colorant [3,4]. A disperse dye has very low water solubility, having affinity for one or more hydrophobic fibers. These are basically nonionic in nature, and are Pol. AbstractUltrasonic (US) energy has revolutionized the dyeing process by introducing the cost and energy effective tools for textile processing. The objective of this research was to use ultrasonic waves as eco-friendly technique to enhance the dyeing process of polyester fabric using disperse red. The fabrics and dye solutions were exposed to ultrasonic waves for 10-60 min. at 60ºC. It was found that 40 min. is the optimal treatment time for fabric to get good colour strength using untreated Disperse Red 343. Whereas good colour strength was obtained by dyeing US treated fabric using non US treated dye solution for 30 min. keeping M:L of 1:60 at pH 10 of dyeing bath. At these conditions not only leveled dyeing was achieved but the good colour fastness characteristics were achieved. It is found that ultrasonic radiation has a great potential to improve the dyeing beahviour of polyester fabric using Disperse Red343 dye.

“…the microwave irradiation as these irradiations have modified the surface of cotton. Wash fastness showed good to better results because of the strong linkage between primary hydroxyl group of cellulosic cotton fabric and reactive group of reactive dye that don't allow the dye molecule to detach from the fabric surface (Kim et al, 2014;Bhatti et al, 2016). This strong covalent bonding also resists when the fabrics were exposed to light, rubbing and dry cleaning.…”

The urge of environmental friendly techniques in textile processing is gaining much attention due to high risks of effluent load causing eco-imbalance. For the present study, the cotton fabric and Reactive Violet H3R dye solution were treated with microwave radiation for 2, 4, 6, 8 & 10 min. at different powers (low, medium & high).Dyeing was performed using un-irradiated (NRC) and irradiated cotton (RC) with un-irradiated (NRS) and irradiated dye solution (RS). Different dyeing parameters were optimized and ISO standard methods for color fastness were employed to rate the color change before and after irradiation. It is found that microwave irradiation for 8 min. at high power has given good colour strength. When 60 mL irradiated dye solution of 7.5 pH containing 8 g/L of salt as exhausting agent is used to dye irradiated fabric at 60 o C for 55 min. ISO standards for colorfastness employed at various shades have shown that microwave irradiation has improved the rating of fastness properties. It is concluded that microwave irradiation has a promising potential to improve the color strength and dyeing properties under mild conditions.
