“…Dyed fabrics, especially wool, exhibited a very large enhancement in UV protection, and it is also stated that dye extract and dyed samples have very good anti-microbial behavior (Rani et al 2020 ). In one study, Iqbal et al ( 2023 ) stressed the use of bio-mordants like Aloe vera and Emblica officinalis (amla) to accomplish sustainable natural dyeing utilizing Dalbergia sissoo on wool. Results indicate that utilizing natural mordants improved the fixing of natural dyes and also enhanced their antibacterial activity.…”

Due to the increasing pressure on environmentally friendly approaches and sustainable production processes, the textile dyeing industry has focused on natural colorants. Thus, the use of bio-mordants, which are biological materials, has become widespread as an alternative to metal salts, most of which are non-ecological, used in the application processes of natural colorants. In natural dyeing, dyers want to use mordant substances in the dyeing processes in order to both expand the color spectrum and improve the fastness properties. Conventional metal salts used in natural dyeing are made up of metallic ions, which, when released into the environment as wastewater effluent at the end of the dyeing process, cause major damage to the ecosystem. Many researchers have thought about using mordants derived from natural sources to address the environmental problem. This article is a review of the investigation of natural mordants used instead of metallic mordants in the process of coloring various textile materials with natural dyestuff sources. It has been determined that many substances, most of them herbal materials, are used as mordants. In this review, mordants, except for conventional metal salts, are examined under three main groups for a better understanding. These groups are as follows: (i) natural or bio-mordants, (ii) oil mordants, and (iii) new-generation and non-vegetable-based mordants. Here, researchers will find an overview of the most recent developments in green mordants as well as application techniques for a variety of mordants.

“…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.…”

“…All things considered, this research presents viable options for effective and sustainable textile dyeing techniques. H. Benli et al [17] and K Iqbal et al [18] conducted research on dyeing of wool fabrics using various natural dye sources. Eyupoglu, C. et al [19] investigated the dyeing properties of mohair fiber using natural dyes derived from Candelariella reflexa.…”
The demand for natural dyes is increasing due to the negative environmental impacts of synthetic color. In fact, customers are becoming more concerned about their health and the environmentally friendly products. The aim of this research is to disclose the dye extraction process using the ultrasonic method and eco‐friendly dyeing of organic cotton knitted fabric. Initially, 10 g of Syzyguim cumini leaf powder was dissolved in 150 mL of purified water maintaining a 1 : 15 M : L ratio to extract the color. After that, the extracted dye solution was added to coloration bath following the M : L ratios of 1 : 16, 1 : 12, and 1 : 8 for producing dark, medium, and light shades, respectively. Post mordanting was done using natural lemon juice for colorfastness improvement. The color attributes were revealed by the spectrophotometric analysis. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to comprehend the successful relationship that exists among SCL dyes and organic cotton fibers, and the TGA analysis confirmed that dyed fabric is more stable than undyed fabric. Moreover, the colored sample‘s pH, formaldehyde level, and presence of forbidden Azo groups (aromatic amines) were examined. The test results revealed that very good to excellent color fastness properties were obtained and no harmful chemicals were detected in the dyed samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
