Sustainable and Environmental Dyeing with MAUT Method Comparative Selection of the Dyeing Recipe

Abstract

The textile industry is one of the most complex sectors, in terms of the materials and chemical processes used from petroleum and the environmental degradation during its production and disposal. It is therefore a sector looking for new possibilities and for more sustainable materials and applications. One option is to use natural dyes, as they are considered biodegradable, do not pollute the environment, and have potential use for many sectors, including the fashion industry. In this study, Alanya silk was dyed by a natural dyeing method with crocus sativus, Helichrysum arenarium, and Glycyrrhiza glabra L., plants that grow in and around the Alanya region. Quercus aegilops L. grown in the region was preferred as mordant, a natural binder, and is one of the plants with the highest tannin content, and it was used with a more environmentally friendly and sustainable approach to increase the binding in natural dyeing instead of chemical mordants. The aim is to provide an environmental and scientific contribution to the dyeing producers in this region. According to the MAUT (Multi-Attribute Utility Theory) method, the best dyes in terms of fastness and color efficiency were determined as the dyes made with the Glycyrrhiza glabra L. plant.

Bio-mordants: a review

“…While examining the use of natural dye obtained from the Sambucus ebulus L. plant in hemp fabric dyeing, gallnut extract ( Quercus aegilops L.) was used as a natural mordant. It is stated that the best dyeing characteristics were obtained using a 15% concentration of Quercus aegilops natural mordant, which was used to dye hemp fabric with Sambucus with the least amount of color difference and the greatest amount of color efficiency (Özomay and Akalın 2022a ; Özomay 2023 ).…”

Green Application of Isolated Colorant from Neem Bark for Mordant-Coated Wool: Optimization of Dyeing and Mordanting for Shade Development

“…In addition to these benefits, these dyes have numerous disadvantages, such as water pollution, the production of carcinogenic chemicals, and hazardous waste as industrial effluents [4]. From an application point of view (color range, low cost, and bright shading), these dyes are widely available and exhibit beautiful properties, yet they may cause dermatologic and genotoxic effects on humans and other living beings [5,6]. Hence, due to such acute and lethal effects of these synthetic dyes, the revival of natural dyes in all fields is underway around the globe.…”

“…Among all mordants, aluminum (Al) is the safest to use and cheapest to buy, whereas chrome (Cr) and Tin (Sn) are the most expensive mordants. However, mordants can reduce the fabric's tenacity [6].…”
