“…However keeping in view the toxic nature of heavy metals, the natural dyeing process was also under strict observation . Thus, the bio‐mordants have been used to make dyeing process more sustainable and more therapeutic . For current studies, two bio‐mordants, turmeric containing curcumin and pomegranate containing tannin as pre and post mordants extracts have been employed under the influence of US treatment.…”

Environmental pollution spread due to frequent use of synthetic dyes has compelled the global community to move toward sustainable and eco‐friendly products. The present research has been conducted to investigate the coloring efficacy of Arjun bark (Terminalia arjuna) for silk fabric under the influence of ultrasonic radiation. Extracts have been prepared in different media and extracts and silk fabrics have been irradiated ultrasonically for 15–60 min at 60 °C. Good color strength is obtained, by dyeing irradiated silk for 65 min at 65 °C, when irradiated extract of pH 3 (RE, 30 mL) obtained from powder (6 g) is used in the presence of salt concentration of 3 g/100 mL. Pre‐chemical mordants such as 5% of Al (Aluminum sulphate) and 9% of Fe (iron sulphate) as well as post‐chemical mordants such as 5% Al (Aluminum sulphate) and 3% of Fe (iron sulphate) have improved the color characteristics. The bio‐mordants employed reveal that 9% of pomegranate and turmeric extracts as pre and post bio‐mordants have given excellent coloring characteristics. It is concluded that Arjun bark has a great potential to act as a source of natural colorant for silk dyeing under the influence of ultrasonic radiation. © 2018 American Institute of Chemical Engineers Environ Prog, 38: S331–S339, 2019

“…31,32 In chemical mordants, a dye complex is formed with metal via coordinate covalent interactions. 33 The greater the amount of the metal used for this complex formation, the greater the fastness rating, but only up to a certain limit. Hence, only a particular amount of chemicals and biomordants can be used to give the desired results.…”

Due to an increasing awareness of the harmful effects of synthetic dyes among the global community, the demand for natural dyes in the textile sector has increased. The current study has been conducted to explore coconut coir, that is, Cocos nucifera, as a new dye yielding plant for wool dyeing under ultrasonic (US) radiation. Unirradiated and US-irradiated extracts of coconut coir were utilized to dye unirradiated and US-irradiated wool fabrics. To make the process more sustainable, acacia, henna, turmeric and pomegranate extracts as biomordants were used to dye wool fabric at 65℃ for 45 min. It was found that a good color yield was achieved by dyeing US-treated wool with US-treated acidic methanolic extract at 65℃ for 45 min. It is found that biomordanting profoundly added value in coloration and also enhanced the fastness rating of the dyed wool fabrics. It is concluded that US rays have excellent efficacy for exploring the coloring wealth of plants for dyeing of natural fabrics.

“…Natural dye applications have been restricted due to low dye fi xation rates and poor color strengths, especially for cellulose cotton-based fabrics [4]. Several approaches have been reported to improve the dyeing process, such as chemical and physical surface modifi cation by enzymatic action, plasma, gamma radiation, or cover materials [5][6][7][8][9][10], modifi cation of solution-surface equilibrium energy [11,2], modifi cation of the dye activation energy by ultrasonic waves [12][13][14], and the use of different mordants, tertiary amines/quaternary ammonium compounds (cationization methods), metal/metalloids salts, tannins, and enzymes [15][16][17][18]. All these methods try to increase the chemical affi nity between the dye and fi ber fabric surface, improving a high electrostatic affi nity or the covalent bond formation [19,20].…”

Cochlospermum vitifolium flowers were evaluated as a raw material of natural dye on different fabrics, natural and synthetic. The dyeing process evaluation was performed by CIELa*b* color coordinates analysis. Color fastness was evaluated using the AATCC 61-1B and AATCC 116 methods. The chemical identification of the compounds in the color fraction was carried out by HPLC–MS/MS. The naringenin was determined to be the color compound. Among the natural textiles, the wool presented the best uniformity of dyeing and fixation of color, achieving the best hue when a pre-mordant treatment was used. The combination of sodium and potassium tartrate dye resulted in the best final hue, between the yellow and red regions of the CIELa*b* space (L = 49.84, a* = 5.41, b* = 45.52). The dyeing of the wool by the sodium and potassium tartrate pretreatment showed the best fastness properties to the laundering test (ΔEab = 54.56), as well as in the rub test (ΔEab = 67.36). The extract of C. vitifolium could be considered as an alternative natural dye for textiles with a protein base (e.g., wool fabrics), obtaining the best results when mordant pretreatment is used.
