Ergonomic Fashion Design: Sustainable Dyes
Authors: Gabriela Santos, Cristina Carvalho
Abstract: Water waste, contamination, and fossil fuel generated energy are acknowledged issues within the textile industry. Current dyeing processes pose serious threat to the environment and human health, often associated with toxic and carcinogenic substances that are released into the environment, through effluents not conveniently treated before being discharged into natural waters. Besides print and pattern, consumers demand for basic characteristics in textiles – these must resist to agents that cause colours to fade. On the other hand, industry must provide a great range of colours and access to huge quantities of coloured substance to dye. Simultaneously, it must be cost-effective. Natural dyes are perceived as less harmful for the environment due to its biodegradable nature. Studies reveal certain natural dyes possess UVR protection properties, as well as antimicrobial and anti-inflammatory assets. Nevertheless, depending on the nature of the dye, there are many advantages and disadvantages to consider.Through an extensive study on various fields such as Biotechnology, History, Ethnography, Biology, Archaeology, amongst many others we gathered information regarding natural coloured compounds, colour sources (plants, animals and microorganisms), ancient and modern techniques of extraction and application. This study shows the evolution of dyes throughout the centuries. It also reveals that the revival of natural dyes in addiction to new cutting edge technologies such as biotechnology might allow for an industrial feasibility.
