“…In the case of dyeing with reactive dyes, jute fabrics dyed with Rifazol Golden Yellow RNL and Rifazol Brilliant Blur R Spc without ultrasound produced color strength 6.22 and 4.74 but in the case of dyeing with sonication, the color strength increased to 7.25 and 5.49 respectively. The findings are consistent with the phenomenon observed for the dyeing of other textile fibers with reactive and basic dyes [12,31]. Probably, ultrasound increases the mobility of dye particles in the dye bath and also breaks down agglomeration of dyes on fiber surfaces that ease higher migration and diffusion of dye molecules from dyebath to the fiber surface and from fiber surface to the interior of fibers.…”

Ultrasonic dyeing has been investigated as a means to increase the diffusion of the dye molecules into the fiber for the dyeing of various fibers. However, for scouring, bleaching, and dyeing of jute fabrics, the beneficial effect of sonication was never realized. In this work, we report the effect of sonicated scouring and bleaching of jute fabrics on their physicomechanical properties and the dyeability in the conventional dyeing with reactive and basic dyes. The sonicated scoured and bleached fabric showed higher whiteness index and weight loss but the tensile strength and yellowness index decreased compared to the conventionally scoured and bleached jute fabric. The sonicated scoured fabric showed partial removal of lignin but the conventionally scoured fabric did not show any change in lignin content. It was found that in the case of conventional dyeing, the sonicated scoured and bleached fabric produced higher color strength than the jute fabric scoured and bleached at the same conditions but without sonication. Moreover, we also investigated the effect of ultrasound on the dyeing and color fastness properties of jute fabric dyed with two reactive and two basic dyes. It was found that the sonicated dyeing produced higher color strength compared to the fabrics dyed without sonication. Both conventional and sonicated dyed fabric showed very similar color fastness properties to light, washing, and rubbing indicating no degradation of dyes occurred during sonicated dyeing.

“…This may be achieved by the various methods such as the use of abundantly available, renewable and clean source of energy from the sunlight. This is possible by enhancing usage of radiofrequency drying, microwave simulated batching [6], infrared heating, ultrasonic dyeing [7] electro chemical dye reduction [8], etc. Such methods conserve energy by ascertaining textile processing and coloration at lower temperatures and within less time.…”

Textile manufacturing is considered to be the mother of industrialization and over the years it has transformed its applications and usage from the basic apparel clothing to the ultra modern technical functions. Viewed as one of the worst polluting industries generating gaseous emission, liquid effluent and solid waste, it is imperative to develop and implement novel methods of processing for enhanced sustainability.

“…To reduce wastewater discharges and environmental impacts, various methods were used to improve the exhaustion and fixation of dyes on wool fiber. These attempts included (a) pretreatment or modification of wool fiber before coloration [10,11,12,13,14,15,16]; (b) synthesis of novel dyestuffs [8,17]; (c) microencapsulation with liposomes [18,19]; (d) reuse of dyebath [20] and seawater [21]; (e) foam dyeing [22]; (g) ultrasound-assisted dyeing [23,24,25]; and (h) solvent-assisted dyeing using mixed solvent [26], supercritical critical fluid, and/or reverse micelle [27,28,29,30,31,32].…”

A Computer Color-Matching Study of Reverse Micellar Dyeing of Wool with Reactive Dyes

Computer color-matching (CCM) and the levelness of poly(ethylene glycol)-based reverse-micellar dyed wool fabrics in octane and nonane were investigated and compared with a conventional water-based dyeing system. Reflectance curves and calibration curves exhibited no chromatic change and maintained high linearity in both dyeing systems. The linearity of water-dyed calibration curves was slightly higher than that of the reverse-micellar dyed curves. The color yield, in term of K/Ssum values, of solvent-dyed samples was found to be generally higher than that of water-based dyed samples at various calibrated dye concentrations. The concentrations predicted by CCM were close to the theoretical concentrations for both dyeing methods. This indicates that octane- and nonane-assisted reverse-micellar dyeing of wool is able to generate color recipes comparable to the conventional water-based dyeing system. The solvent-dyed samples, measured by the relative unlevelness indices (RUI), exhibit good-to-excellent levelness, which is highly comparable with the water-dyed samples.
