“…Depending upon the mode of isolation, the dyeing conditions and the optimum amount of metal salt used (%) has given the variety of shades with yellowish red tones through metal-dye complex formation onto fabric, where the reduction and polarizing powder of metal is the key factor. 21,53 The color coordinates given in Table 1 reveal that mostly the chemical mordants have produced brighter shades with reddishyellow hue but the application of 7% of tannic acid (T.A.) during dyeing (meta) of US treated silk fabric (RSF) with the U.S. treated aqueous extract of harmal seeds at optimal conditions has given darker shade (L* = 50.32) with reddish-yellow tone (a* = 9.07; b* = 21.85).…”

Global heat, carcinogenic, and viral diseases created due to industrial pollutants has led people to shift toward natural products particularly natural dyes in all walks of life. In this study, U.S. rays up-to 60 min, were used to extract the color in aqueous medium and employed onto silk fabric at selected conditions. It has been observed that good color strength has been found when 30 mL of acidic extract ( pH = 4.0) obtained from 6.0 g of Harmal powder containing 3.0 g/100 mL of salt as an exhausting agent was employed onto the US treated silk at 65ºC for 55 min. The utilization of the extract obtained from 7% of pomegranate as post-bio-mordant, 3% of acacia extract as meta-bio-mordant, and 7% of henna extract as meta-bio-mordants has given excellent color strength. In comparison, 5% of Al salt as meta mordant, 5% of Fe salt as pre mordant, and 7% of tannic acid as meta-mordant has given better results. ISO standard methods for fastness employed onto optimum mordanted dyed fabrics have given well to excellent fastness ratings. Hence, natural colorant extracted from Harmal seeds has excellent coloring efficacy to dye silk fabric under sustainable conditions, whereas the addition of eco-friendly mordants for shade development process has made the coloration of silk more sustainable with improved colorfastness properties.

“…Mordan membentuk ikatan yang cukup kuat dengan gugus hidroksil dan karbonil pada pewarna tetapi dalam hal ini kompleks koordinasi yang lemah terbentuk dengan gugus hidroksil dari benang. Manicketh et al (2021) membuktikan proses mordanting paling baik diterapkan pada benang sutra, benang kapas/katun dan poliester. Persentase kejenuhan pewarna rendah pada Jurnal Gema Ngabdi Vol.…”

Dyeing woven yarn using natural dyes is increasingly popular, but the process is complicated, color consistency is low, fades easily and color choices are limited. Service activities in Sukarara Village in the form of socialization and assistance on coloring techniques using pH-based anthocyanins (acidity degrees) were carried out as a solution to these problems. By varying the pH of the anthocyanin solution using buffer 2-10 followed by fixation/mordanting, more color variations (one type of plant extract), consistency and color resistance were achieved. The activity partners are 20 members of the Subahnale Tourism Awareness Group (Pokdarwis). Activities include FGD, interviews, socialization, mentoring and evaluation. The activity was carried out well without significant obstacles with an increase in the average value of partners from 55 to 87. It is hoped that Pokdarwis can synergize with the village government for the sustainability of activities so that the role of woven fabrics positively contributes to the community welfare.

“…A series of studies using lemon juice as a mordant can be summarized as follows: alum, acetic acid, CuSO 4 , and lemon juice were used to dye cotton, silk, and polyester yarns using different natural dye sources such as sepals of Mussaenda hybrid, fruits of Carissa carandas, Syzygium cumini, pink leaves of Cordyline fruticosa, and red sepals of Mussaenda erythrophylla. It has been reported that different color tones can be obtained, from pale yellow to green, depending on the mordant agents(Manicketh and Francis 2020;Manicketh et al 2021Manicketh et al , 2022 Arain et al (2021). used lemon as a bio-mordant to provide an environmentally friendly dyeing process for polyester fabric with henna.…”

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.
