Abstract
Subject headings
Close
- Textile-to-textile recycling from cotton textiles can be done either mechanically or chemically. In chemical textile recycling of cotton there are challenges to overcome in order to regenerate new fibres. Two of the challenges among others are reactive dyes and wrinkle-free finishes that could disturb the regeneration process steps since these finishes are covalently linked to the cellulose.This poster discusses the impact of using a novel alkaline/acid bleaching sequence to strip reactive dyes and wrinkle-free finish (DMDHEU) from cotton textile for production of regenerated viscose fibre properties. The results might generate a promising step forward to overcome quality challenges for cellulosic chemical recycling.
