The textile industry, a cornerstone of global manufacturing, faces increasing scrutiny regarding its environmental impact, particularly in coloration processes. Conventional dyeing methods are notorious for high water and energy consumption, alongside the generation of significant wastewater effluent laden with chemicals. Recognizing this challenge, a growing body of research is dedicated to developing and implementing sustainable dyeing techniques that mitigate these adverse effects. This ongoing exploration aims to transform the textile sector towards more environmentally responsible practices, aligning with global sustainability goals and consumer demand for eco-conscious products. The exploration of novel eco-friendly dyeing techniques for cotton and polyester is a critical area of focus, concentrating on reducing water and energy consumption. These advancements highlight the potential for natural dyes and biodegradable auxiliaries, alongside innovative methods like supercritical fluid dyeing and plasma treatment, to significantly lower the environmental footprint of textile coloration while maintaining or improving dye fastness and fabric properties. The findings suggest a promising shift towards more sustainable textile manufacturing processes [1].
Further investigations delve into the application of plant-derived dyes specifically for cotton, detailing the optimization of dyeing parameters to achieve high color yield and fastness. Comparisons of different extraction methods and mordanting techniques, alongside data on wash and light fastness, underscore the viability of botanical sources for sustainable textile coloration. This approach offers a greener alternative to synthetic dyes and contributes to reducing effluent pollution [2].
Supercritical carbon dioxide (scCO2) dyeing for polyester fabrics has emerged as a significant area of study, examining the influence of pressure, temperature, and dyeing time on dye uptake and fastness properties. This research demonstrates that scCO2 dyeing provides a solvent-free and energy-efficient method, substantially reducing water usage and eliminating wastewater discharge, positioning it as a highly sustainable option for polyester coloration [3].
The development of biodegradable auxiliaries for the reactive dyeing of cotton is another key area of advancement. This work investigates new formulations of wetting agents and leveling agents derived from renewable resources, showing that these bio-based auxiliaries not only maintain dyeing performance but also significantly improve the biodegradability of the dyeing effluent, thereby contributing to a reduced environmental impact [4].
Plasma pre-treatment is explored as an effective method to enhance the dyeability of polyester fibers with disperse dyes. By examining the effects of atmospheric pressure plasma on the surface properties of polyester, this research indicates that plasma treatment improves dye uptake, reduces dyeing time, and allows for lower dyeing temperatures, consequently contributing to energy savings and enhanced environmental sustainability [5].
The utilization of microalgae biomass as a source for natural dyes in cotton coloration is also being investigated. This research details the extraction of pigments and their application in a dyeing process, evaluating the resultant color properties and fastness. The work highlights the considerable potential of utilizing abundant microalgae resources for eco-friendly textile coloration, offering a sustainable and renewable alternative [6].
Innovative approaches to dyeing polyester using a water-bath method with reduced water and energy consumption are being developed. These methods explore novel dispersant systems that facilitate efficient dye dispersion in a lower liquor ratio. The studies demonstrate that this modified water-bath dyeing can achieve fastness properties comparable to conventional methods, coupled with significant environmental benefits [7].
The use of ionic liquids as a green solvent for vat dyeing of cotton is gaining traction. This research investigates dye uptake and fastness properties in ionic liquid media, suggesting that these solvents offer a promising eco-friendly alternative to traditional water-based dyeing. Their application minimizes wastewater generation and improves dye exhaustion [8].
Optimization of ultrasonic-assisted dyeing for cotton using natural dyes is another avenue being explored. The impact of ultrasonic parameters on dye penetration and color yield is examined.
