  Abstract

Over a decade ago, deep eutectic solvents (DES) were introduced and have since found diverse applications due to their unique chemical and physical properties. Recently, they have gained considerable attention, especially in nanotechnology, being hailed as “new green solvents." In this study, we explore choline chloride (CC) as a DES due to its non-toxic and cost-effective nature, as well as its ability to enhance color yield properties of disperse dyes on nanofibers. Cellulose acetate nanofibers (CANF) were electrospun and subsequently dyed with CI Disperse Red 277, CI Disperse Blue 165:1, and CI Yellow 211 using the high-temperature exhaust method in two different media: choline chloride:ethylene glycol (CC:EG) and choline chloride:urea (CC:urea). The results revealed that CANF dyeing through the CC:EG media exhibited superior color fixation properties compared to the CC:urea media. Characterization of the dyed samples was conducted through Fourier transmission infrared (FT-IR) and scanning electron microscopy (SEM), while the thermodynamic, standard affinities, and kinetic parameters were also analyzed. The novel method of dyeing cellulose nanofibers (CANF) with deep eutectic solvents (DES) not only demonstrated outstanding calorimetric properties but also required a significantly shorter duration compared to traditional dyeing processes. This breakthrough in dyeing technology brings forth numerous benefits. First, the dyeing of nanofibers in DES has proven to be environmentally friendly. Using DES as a dyeing medium, it offers a promising alternative to water, and auxiliary chemicals typically used in traditional dyeing methods. This reduces the overall negative environmental impact, making it a more sustainable choice. Additionally, the use of DES in dyeing CANF results in enhanced calorimetric properties, thereby improving the overall quality of the dyed fibers. Furthermore, the shorter duration required for dyeing with DES saves time and energy, making the process more efficient. Overall, this innovative approach to dyeing CANF with DES brings together environmental sustainability, improved product quality, and increased efficiency, making it a game-changer in the textile industry.
