“…An attempt was made to dye cotton in a dye/decamethyl cyclopentasiloxane (D5) suspension system using reactive dye . The optimal dyeing process included: (i) ball milling the dye with oleic acid; (ii) adding D5 to prepare the dye/D5 suspension system; (iii) soaking the sample in soda ash solution and padding it to gain 140% pick‐up; and (iv) dyeing the fabric in the dye/D5 suspension system.…”

“…Due to growing environmental concerns, several alternative methods for dyeing cotton fibre have been investigated and reported in the literature, including neutral pH dyeing, supercritical carbon dioxide dyeing, reverse micellar dyeing, low‐salt or salt‐free dyeing, clay nanoparticle dyeing, silicone‐based dyeing, two‐solvent miscible dyeing, dyeing with reused wastewater, dye‐solvent suspension dyeing and natural mordant dyeing . The addition of different dyeing methods, modifications of fibre properties (such as cotton cationisation and polymer grafting on cotton), inventions of new reactive dyes with reduced requirements for salt and soda ash, and advancements in effluent treatment technologies, have also been reported.…”

This study reviews the evolution of and recent developments in non-aqueous reactive dyeing systems for cotton fibre. As conventional water-based reactive dyeing causes adverse effects to the environment because of the need for huge quantities of water and chemicals, as well as generating a substantial amount of effluents, one of the alternative ways to alleviate pressure on the environment is to switch the dyeing medium from an aqueous water-based approach to a non-aqueous solvent-assisted approach. Among a wide variety of non-aqueous dyeing methods, this review focuses on several non-aqueous dyeing systems, including dyeing textile fibres with chlorinated solvents, dyeing cotton with the use of reverse micellar systems, a dye/ solvent suspension system and a non-nucleophilic solvent-assisted dyeing system.

“…In our previous investigations [6,7,8,9,10], the siloxane non-aqueous medium (Decamethyl cyclopentasiloxane) was chosen as a continuous phase medium to prepare the siloxane non-aqueous dyeing system for dyeing natural fiber with reactive dye [11]. Siloxane non-aqueous medium is a clear, odorless, colorless, and non-oily cyclic siloxane fluid, which is widely used in consumer and industrial applications [12,13,14].…”

Diffusion Mechanism of Aqueous Solutions and Swelling of Cellulosic Fibers in Silicone Non-Aqueous Dyeing System

The main goal of this article is to study the diffusion mechanism of aqueous solutions and the swelling of cellulosic fibers in the silicone non-aqueous dyeing system via fluorescent labeling. Due to non-polar media only adsorbing on the surface of fiber, cellulosic fiber could not swell as a result of the non-polar media. However, because water molecules can diffuse into the non-crystalline region of the fiber, cellulosic fiber could swell by water which was dispersed or emulsified in a non-aqueous dyeing system. To study the diffusion mechanism of an aqueous solution in the siloxane non-aqueous dyeing system, siloxane non-aqueous media was first diffused to the cellulosic fiber because of its lower surface tension. The resulting aqueous solution took more time to diffuse the surface of the cellulosic fiber, because water molecules must penetrate the siloxane non-aqueous media film. Compared with the fluorescent intensity of the fiber surface, the siloxane film could be re-transferred to the dye bath under the emulsification of the surfactant and the mechanical force. Therefore, a longer diffusion time of the aqueous solution ensured the dyeing feasibility for cellulosic fiber in the non-aqueous dyeing system.

“…Recently, attempts have been made for the preparation of D5 reverse micelles and the evaluation of water solubilization performance in the dyeing system [35]. Further experiments were conducted to develop a dye/D5 suspension dyeing system using a selected surfactant [36,38,39]. The hydrolysis kinetics of this system was also studied [40].…”

Computer Color Matching and Levelness of PEG-Based Reverse Micellar Decamethyl cyclopentasiloxane (D5) Solvent-Assisted Reactive Dyeing on Cotton Fiber

et al. 2017

The color matching and levelness of cotton fabrics dyed with reactive dye, in a non-aqueous environmentally-friendly medium of decamethylcyclopentasiloxane (D5), was investigated using the non-ionic surfactant reverse-micellar approach comprised of poly(ethylene glycol)-based surfactant. The calibration dyeing databases for both conventional water-based dyeing and D5-assisted reverse micellar dyeing were established, along with the dyeing of standard samples with predetermined concentrations. Computer color matching (CCM) was conducted by using different color difference formulae for both dyeing methods. Experimental results reveal that the measured concentrations were nearly the same as the expected concentrations for both methods. This indicates that the D5-assisted non-ionic reverse micellar dyeing approach can achieve color matching as good as the conventional dyeing system. The levelness of the dyed samples was measured according to the relative unlevelness indices (RUI), and the results reveal that the samples dyed by the D5 reverse micellar dyeing system can achieve good to excellent levelness comparable to that of the conventional dyeing system.
