“…Natural dyes are flavonoids, anthocyanidins, carotenoids, quinonoids, benzoquinone, naphthoquinone and anthraquinoids. Tannins are flavonoids extracted from the bark of various plants including Biancaea sappan , 6 cinnamon, 7 Ziziphus , 8 and Dalbergia sissoo , 9 leaves of Berberis thunbergia , 10 and pomegranate, 11 flowers of Hibiscus sabdariffa , 12 Hibiscus rosasinensis , 13 Crocus sativus , 14 and skins/peel of Citrus sinensis L. 15 The natural dyes extracted from fruits studied for wool fibre dyeing may include myrobalan, 16 chamomile, 17 peanut shell, 18 and anthocyanin pigments extracted from the peel/skins of various fruits, including red cabbage, 19 and dragon-berries. 20 Tannins and other flavonoids are advantageous as some of them have antioxidant and antibacterial properties that make the treated fabric multifunctional.…”

“…Mostly, tannin and other polyphenols extracted from barks, leaves, flowers, fruits, and fruit skins were studied for the dyeing of wool. Tannins extracted from barks of various plants, including Ziziphus, cinnamon, walnuts, Azolla pinnata extract, and Cassia reingera, were found suitable for the dyeing of wool fiber. Natural dyes extracted from leaves of pomegranate, Berberis thunbergia, hibiscus flowers, Hibiscus rosa-sinensis, Crocus sativus, skins/peel of Citrus sinensis L., and various fruits, including myrobalan, chamomiles, and peanut shell, are also studied as an alternative to synthetic dyes.…”

Lignin is an abundant and complex biopolymer with inherent color but has only a few applications. It has the potential to replace synthetic acid dyes for the coloration of wool fibers in brown shades, as traditional dyeing with acid dyes produces toxic effluent needing costly treatment. In this work, the valorization of sulfonated lignin was explored by using it as a natural dye for the coloration of wool fabrics alone and with hydrogen peroxide (H 2 O 2 ). The dyed fabrics were characterized by reflectance and diffuse reflectance spectroscopies to assess the color yield and ultraviolet (UV) protection performance, respectively. The dyed fabrics exhibited reasonably good color yield and satisfactory colorfastness to washing (Grade 3/4), which improved to Grade 4 by the oxidation treatment with H 2 O 2 . The scanning electron microscopy (SEM) images show that when fabrics are dyed alone with lignin, deposition of lignin particles is visible on the fiber surface, but with hydrogen peroxide, no deposition of lignin is visible on the fiber surface, and the color strength of the fabric became almost double. The UV light transmission through the fabric decreased from 6.73 and 13.23% at 311 and 365 nm to 2.19 and 5.23%, respectively. The attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectra of the dyed fabrics showed increased absorption of lignin sulfonate by the fabric, suggesting depolymerization of lignin by H 2 O 2 to smaller macromolecules easing absorption into the wool fiber. Lignin sulfonate could be a cheap and sustainable alternative to harmful synthetic dyes for producing brown shades on wool fabric.

“…However, this coloring process results in the consumption of large amounts of water, which generates a considerable amount of colored wastewater 1,2 . The wastewater containing dyes causes serious environmental and health problems 3–6 . They inhibit the penetration of light and photosynthesis activity of water plants and cause a large number of diseases, such as allergic dermatitis, skin irritation, cancer, mutation, and so forth.…”

The present study is interested in removal of a cationic dye gentian violet (GV) using a polystyrene membrane (PS) activated with oleic acid (OA). These innovative membranes were developed by using PS as the base polymer and OA as extractant. The best matrix obtained was characterized by using Fourier transform infrared spectroscopy (FTIR) and x‐ray diffraction (XRD), and then applied in the extraction of a cationic GV dye. The effects of an extraction ratio (OA/PS) in the PS‐AO matrix, initial GV dye concentration ([GV]0), and pH of the solution were studied in a batch reactor. The thermodynamic parameters (, , and ) have been calculated. Therefore, the GV extraction onto the PS‐OA matrix is an exothermic and spontaneous process. In addition, the slop method confirms that the chemical formula of the extracted OA‐GV complex is GV‐RHR. The central composite design (CCD) was used to determine the conditions of each experimental run, and extraction optimization was achieved using response surface methodology (RSM). The results showed that the quadratic regression model was statistically significant (0.9994), and the parameters studied had a profound effect on the extraction efficiency. The optimum GV extraction efficiency of 99% was achieved at an extractant ratio of 1, pH of 8, and [GV]0 of 10 mg L−1. The findings of the current study reveal that PS‐AO matrix is an advantageous and effective membrane for the extraction of GV from aqueous solutions, both environmentally and economically, it can be regenerated and used up to five times.
