“…Water pollution is caused by the addition of unwanted substances or foreign matter that significantly alter the original characteristics of water [31]. In the dyeing processes, water pollution comes from the high concentrations of chemicals, such as salt, dye, soap agents, surfactants, acid, peroxides, and softeners that are present in the textile effluent [3,4,32].…”

“…In conventional textile dyeing, 1 tonne of fabric could result in the pollution of up to 200 tonnes of water. The wastewater produced in textile processes is highly colored and contains complex concentrations of chemicals, such as salt, dye, detergents, peroxides, and heavy metals [3][4][5]. In addition to water pollution, other environmental issues emerge from the burning of fossil fuels, which result in atmospheric emissions and contribute to climate change and greenhouse gases.…”

Ecological Approaches to Textile Dyeing: A Review

Conventional dyeing processes currently practiced in the textile industry have a great environmental impact, mainly in relation to the quantity and pollution of water, use of toxic chemicals, atmospheric emissions, and high energy consumption. This study aims to discuss the relationship between the variables that involve conventional dyeing processes and environmental issues. It presents the mapping of the materials and emerging technologies for ecological coloration, specifically for the pretreatment and dyeing stages. Regarding pretreatment, it discusses biochemical (enzymes) and physical treatment (ultraviolet radiation, plasma, and ozone technology) approaches. With respect to the dyeing processes, it addresses ecological materials (natural dyes) and emerging technologies (such as plasma, supercritical CO2, AirDye®, ultrasonic, microwave, Nano-DyeTM, and electrochemical). Given the importance of ecological coloration, this study provides important reflections on the urgency of resolving issues related to barriers and economic viability in the implementation of the alternatives presented and demonstrates the need to develop educational projects to prepare fashion and textile professionals.

“…A significant amount of metal ions remains unexhausted in the mordant baths used during synthetic dye dyeing production, which are then discharged into wastewater [2]. The wastewater generated from textile processes is characterized by intense colouration and contains complex concentrations of chemicals such as salts, dyes, detergents, peroxides, and heavy metals, raising concerns and negative impacts on https://doi.org/10.31881/TLR.2024.088 ecology and public health [3,4]. The United Nations 2030 Agenda for Sustainable Development proposes a broad and ambitious vision for social, economic, and environmental development [5].…”

Synthetic dyes are the primary colouring materials for textile dyeing; however, the residual industrial wastewater from the dyeing process contains complex concentrations of chemical substances, which result in toxicity and environmental pollution with severe negative impacts on ecology and health. This study adopts an eco-friendly perspective, utilizing a mixture of lychee leaves and sappan wood extracts for dyeing silk-linen fabrics. It explores the impacts of dyeing time, mordants, and dyeing methods on the colour quality of the samples. A computer colourimeter was used to compare the colour effects of different dye solution ratios on silk-linen fabrics, and the colour fastness to water, perspiration, and dry rubbing of the dyed fabrics was tested. The results show that the optimized dyeing process for silk-linen fabrics using a mixed solution of lychee leaves and sappan wood includes the following findings: Dyeing time has no significant impact on the CLE L*, a*, and b* values. The highest L* value and colour brightness are achieved under conditions without mordants. By mixing dye solutions in different proportions and treating them with mordants, the colour gamut of silk-linen fabrics has been expanded. The dyed colours are similar to the main popular colours of 2024, making them the trend colours of this year; the samples' fastness performance tests indicate that the colour fastness to water, perspiration, and dry rubbing essentially meets the requirements for textile fabrics. The use of lychee leaves and sappan wood for fabric dyeing is not only environmentally friendly but also possesses significant health-beneficial properties, offering potential commercial value.
