  • Circular colour: Reusing colour from previous textile lifecycles in textile finishes

Ribul, Miriam, 2023, Conference or Workshop, Circular colour: Reusing colour from previous textile lifecycles in textile finishes at 5th Product Lifetimes and the Environment (PLATE) Conference in Aalto University, Espoo, Finland, 31 May – 2 Jun 2023.

Abstract or Description:

Colour is a key component of textiles, drawing interest while also changing with the seasons, which calls for a systemic perspective of its materials circularity in the context of future product lifetimes. To develop new design processes with regenerated cellulose obtained from post-consumer textiles, an exploration of solely undyed materials is not consistent with the reality that established design techniques produce a wide range of multi-coloured textiles. On the other hand, the presence of dyes reportedly impacts on chemical recycling, and conventional dyestuff for cellulosic materials is often oil-based and includes persistent dyestuff made up of unknown chemicals. Keeping the dyes of discarded textiles in a closed loop would replace the need for new dyestuff, reducing the use of water and energy for dyeing and de-dyeing processes, and avoiding the dispersion or landfill of potentially hazardous chemicals. This paper presents a textile technique that reuses the colour from waste textiles as the dye for cellulose-based textile screen printing processes. This was developed from the interaction and integration of textile design techniques with materials science processes for cellulose regeneration using a methodology developed by the author. When printed textile finishes reuse the colour from the cellulose source from previous textile lifecycles, no added dyes are needed, and the resulting mono-material textiles are compatible within the context of the circular bioeconomy. The results facilitate a material’s future circularity, since the reused dyes do not disrupt the chemical recycling process in the regeneration of colourful, cellulose-based textiles for future product lifetimes.
