“…Where qm denotes the maximal dye absorption per unit weight of fiber (mg/g) which, at a high equilibrium dye concentration Ce(mg/L), creates a full monolayer covering on the fiber surface qe, expresses the adsorbed amount of dye per unit weight of fibre (mg/g) at equilibrium, and KL denotes Langmuir constant refers the adsorption energy (L/mg). The intercepts and slopes of the straight lines derive from Ce/qe versus Ce are used to compute the values of qm and KL [39,40].…”

“…The result suggested that while the MLR increases, the dye adsorption on chitosan treated cotton fabric decreases; and maximum dye adsorption for RRedRR and RYellowRR was 0.00045 mg/g and 0.0753 mg/g at 1:10 ratio respectively. This was happened as a large liquor ratio needed more energy for the movement of the dye particle, and it showed less affinity to the fibre due to the significant distance while in case of shorter material to liquor ratio, the dyeing equilibrium reached rapidly [40,55].…”

The adsorption performance, kinetics, and thermodynamic parameters of reactive dyes on chitosan-treated cotton fabric are described in this research. The batch experiment was carried out to investigate the influence of pH, time, temperature, dye concentration, and material to liquid ratio of Remazol Red RR and Remazol Yellow RR, two widely used reactive dyes. The adsorption of red and yellow dyes was observed at λmax 517 and 419 nm respectively. For both Remazol Red RR and Remazol Yellow RR reactive dyes with starting dye concentrations of 0.0667 and 40 mg/L, the greatest dye adsorption was reported at pH 11 (0.0009 and 0.1284 mg/g) and pH 4 (0.0004 and 0.1038 mg/g). The adsorption performance was investigated using the Langmuir and Freundlich isotherms. The adsorption behaviours of the two reactive dyes closely matched to the Langmuir adsorption isotherm (R2>0.98) than Freundlich isotherm (R2>0.92). The pseudo-second-order kinetic model (R2>0.99) was followed by the dyeing kinetics of modified cotton sample. Thermodynamic investigation was covered with enthalpy change (ΔH⁰), Gibbs free energy (ΔG⁰) and entropy change (ΔS⁰) where all the values were reported positive confirming that the adsorption process was non-spontaneous, endothermic and the higher affinity of reactive dye on chitosan treated cotton.

“…Nevertheless, each textile substrate has its own inherent drawbacks, which require special finishing processes. Wool, for instance, suffers from two major problems, namely, its felting shrinkage when subjected to mechanical agitation while wet, and its susceptibility to moth larvae attack Thus, various chemical, physical, and biological methodologies were proposed to produce machine-washable and insect-resistant woolen products. − Reactive dyes are normally used to dye cotton fabrics in an alkaline solution − while acid and reactive dyes are used to dye wool fabrics in an acidic medium. , Also, acid dyes can be applied to cotton fabrics after modifying the surface with a cationic group or β-cyclodextrin . Polyester textiles (PETs) as synthetic fibers dominate the garment and textile industry .…”

A very promising green chemistry concept that should gain more traction is the introduction of semiprepared azo dyes, which are made by modifying natural extracts with the azo group. This would reduce the dependency on toxic and nonbiodegradable synthetic dyes while also giving economic value to agricultural wastes. In the current study, an extract of peanut red skin was used as an agro-waste and a source of polyphenols to prepare azo dye by coupling it with a diazonium salt of ρnitroaniline. Then, the prepared dye was used to dye and improve the functional properties of natural cellulosic (cotton) and proteinic (wool) as well as synthetic (polyester) fabrics by using microwave irradiation, with a focus on the kinetic and isothermal adsorption aspects of dyeing processes. The effect of different parameters on fabric dyeability was studied using K/S and the CIE L* a* b*. The effect of dyeing on the multifunctional properties of dyed fabrics was investigated. The adsorption kinetics, isotherms, and mechanism studies of the dyeing process were investigated. The results show that after the fabrics were dyed with the prepared dye, a decorative color was obtained. The dyed fabrics showed very good fastness properties. The dyed fabrics showed excellent UV protection, excellent antimicrobial activity, and very good antioxidant properties. The adsorption kinetics was accurately represented by the pseudo-second-order kinetic model. The Temkin and Nernst models with the best correlation coefficients were discovered to be the most acceptable isotherm models.
