“…4 In the conventional water-based textile reactive dyeing process, a huge amount of inorganic electrolyte, alkali and unsettled dye is drained to dyeing wastewater [5][6][7][8] which increases the pollution load and that is nearly unavoidable. [9][10][11] In order to reuse the wastewater from dyeing industries and reducing water pollution, treatment of effluent and recycling of wastewater plays an important role. 12 Though various new colouring techniques have evolved to resolve the pollution impact of the dyeing wastewater, limited methods could be commercialised to reduce or remove the ecological problems.…”

The replacement of inorganic salt and alkali in the reactive dyeing of cotton textiles with organic biodegradable compound has been explored in recent years. We report the use of organic salt, tetra sodium salt of glutamic acid diacetic acid (GLDA-Na 4 ) in the batchwise dyeing of cotton garment as an exhausting and fixing agent. The reactive dye, CI Reactive Black 5 was selected for the present study. The results revealed that the maximum K/S value of 25.5 and fixation of 90.74% was obtained using GLDA-Na 4 at laboratory scale experiments. Furthermore, the effluent samples test results demonstrated considerably reduced total dissolved solids (TDS) and chemical oxygen demand (COD) contents with GLDA-Na 4 in comparison to the inorganic chemicals. The colourfastness to light, rubbing and washing have demonstrated similar ratings with GLDA-Na 4 and inorganic chemicals. The tensile strength of samples was enhanced by using GLDA-Na 4 .

“…Besides, dye fixation is unsatisfactory in organic solvent dyeing system. Decamethylcyclopentasiloxane (D5)-water system (Fu et al 2015;Pei et al 2021), oil-water system (Liu et al 2019;Mu et al 2019a;Mu et al 2019b) and ethanol-water system (Wang et al 2020;Xia et al 2021;Xia et al 2018) also have been investigated to realize the aim of clean dyeing since the 1950s. The dye and D5 could form the dyeing system by ball-milling and reversed micellar, which could realize cotton dyeing without salt.…”

Aqueous reactive dyeing of cotton is considered to be environmentally unfriendly owing to its high consumption of water and salt as well as large discharge of wastewater. However, the industrial applications of current alternative dyeing technologies are difficult to realize due to different problems such as poor dyeing quality, environmental pollution and high cost. Herein, we developed a hydrophobic deep eutectic solvent (HDES) dyeing approach using natural thymol-menthol to overcome the problems caused by reactive dyeing of cotton. HDES dyeing approach could achieve excellent dyeing properties of cotton by optimizing water content, pick-up and concentration of alkali solution. Dye fixation kinetics of HDES dyeing system was studied based on Lagergren pseudo-first-order and pseudo-second-order dynamics models, compared with aqueous dyeing system. The cotton fabrics dyed in Thy-Men system exhibited excellent levelness, satisfactory colorfastness and color strength without addition of salt. Furthermore, HDES can be reused for 5 cycles of dyeing and the dyed fabrics displayed consistently high color strength values. This dyeing approach provides substantial reduction in wastewater emission and consumption of freshwater and chemicals, which has considerable potential for promoting cleaner production in the textile industry.

The objective of this work is to study the influence of the plain, twill and satin weave structures on the colorfastness properties of reactive dyes. From the results, it can be concluded that plain weave fabric showed the optimum colorfastness properties due to its compact interlacement structure compared to twill and satin weave fabrics. Three types of plain, twill, and satin weave fabrics of different weave structures and weights (g/m2) were used in this research. The dyes, auxiliaries, and chemicals were applied, and the colorfastness tests were carried out in accordance with the test methods provided by ASTM and AATCC standards. Color strength (K/S) values were obtained using a reflectance spectrophotometer. A projection microscope was used to take cross sectional diagrams of the yarns for assessment. FTIR instrument transmitted infrared radiation to the dyed samples of up to a few microns to measure the spectroscopy within the visible spectral province with the maximum infrared ray (IR) peak values. The peak values of the FTIR device assured the presence of colorant or chromophore existing in the dyestuffs which were liable to expose the best colorfastness properties. This research is experimentally-based, and the findings are useful to personnel involved in cellulose fabric dyeing with reactive dyes and to the control of color properties. This research opens potential ways for scholars to advance study in this field.
