Natural dyeing is an ancestral craft that dates back to the earliest civilizations. This art perfectly aligns with the eco-design approach sought by many textile industries. Indeed, the fashion industry is rethinking its ways of manufacturing, consuming, and reducing the use of all substances that lead to water contamination and environmental pollution. The industrialization of ancestral dyeing is a process adopted by several Tunisian textile companies. However, this process is somewhat complex due to the sophisticated techniques involved, with Tie-dye being one of the prominent methods. 

In this context, this article explores the fusion of this ancient technique with eco-design to reinvent modern textiles. By highlighting the Tie and Dye technique, the study examines how these methods can be integrated into sustainable design practices. The aim is to demonstrate that ancestral know-how can not only preserve cultural heritage but also offer innovative and ecological solutions to contemporary environmental challenges. This article discusses the results of our research on the industrialization of the traditional Tie and Dye effect and the exploration of new horizons in ‘textile’ eco-design within the Tunisian textile development laboratory, Chimitex, through the use of plant-based dyes.
