“…Some organic compounds are used directly as organic mordant agents in reactive dyes. Baig et al ( 2019 ) used sodium citrate, ammonium acetate, and potassium acetate as organic mordants in their study. It is reported that out of these three salts, sodium citrate demonstrated superior fastness characteristics in comparison to other salts, while organic salts displayed greater K/S ratios at lower concentrations.…”

“…It has been stated that the use of natural mordants increases the color's strength (Kim et al 2005). Baig et al (2019) used sodium citrate, ammonium acetate, and potassium acetate as mordants in their studies. According to the paper, among these three salts, sodium citrate showed superior fastness properties to other salts, while organic salts showed higher K/S ratios at lower concentrations.…”

“…It is stated that the dye absorption and K/S value of silk fabrics were successfully increased by mordanting with terrae rare (Praseodymium chloride) and monascorubrin pigment. Baig et al (2019) used sodium citrate, ammonium acetate, and potassium acetate as mordants in their studies. In the study, sodium citrate outperformed other salts in terms of its fastness properties, while organic salts displayed better K/S ratios at lower concentrations.…”

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.

“…1 Some chemicals, such as heavy metals, organic dyes and alkalis, may cause toxic impacts on biological health and ecological safety. 2 As necessities in our daily life, textiles and apparel products are in great demand, 3 which inevitably increases the consumption of textile chemicals and the amount of chemical pollutants discharged into the environment. Therefore, chemical management and control in the production processes of textiles and apparel products is very important, and it is essential to establish an effective environmental impact assessment method for textile chemicals.…”

Control quantity or toxicity of textile chemicals? A case study of denim jeans in the warp-dyeing phase

The extensive use and discharge of chemicals is one of the main factors leading to serious environmental pollution in the textiles and apparel industry. The chemical footprint (ChF) is a toxicity-based chemical management method that is used to quantitatively evaluate the potential toxic effects of chemical pollutants discharged during the production of textiles and apparel products on human health and environmental safety. Compared with the traditional quantity-based method, this method needs to simulate the entire process of chemicals from discharge to impact, involving a series of steps of fate, exposure and effect, which greatly increases the difficulty of modeling. A scientific question is whether it is worth spending so much effort to quantify the toxicity of chemicals. Taking the warp-dyeing phase of denim jeans as an example, this paper calculated the ChFs for both human and ecological toxicities of textile chemicals based on the USEtox model, and compared them with the values of discharge quantities. The results reveal that there is a certain inconsistency between the discharge quantity and toxicity of chemical substances. Relying solely on the amount of chemicals discharged can sometimes lead to misjudgments, emphasizing the importance of controlling the toxicity of chemicals.
