Synthesis and Characterization of Stereoselective Ozonides for Sustainable Textile Wet Processes

This study focuses on the stereoselective synthesis of ozonides for potential applications in different textiles processes. By synthesizing controlled ozonide in a closed-circuit reactor, high stereoselectivity (>90% ozonide formation) was achieved, enabling sustainable denim fading, cotton bleaching and/or different textile washing processes. This method will significantly reduce water usage and chemical discharge compared to traditional processes. In-depth analyses using UV-vis spectroscopy, FTIR, NMR, X-ray diffraction (XRD), cyclic voltammetry (CV), and oxidation-reduction potential (OPR) measurements demonstrate selective chromophore degradation without cellulose degradation, confirming the role of ozonide intermediates in targeted oxidation. This innovation aligns with the EU Green Deal principles, which promote circular economy applications in textiles. Its scalability and low energy profile highlight its applicability for eco-efficient textile production.
