The fibres were regenerated from N-methyl N- morpholine oxide (NMMO) solution and then analysed using XPS. The high resolution spectra of the analysed fibres indicated that the fibres regenerated from cotton waste garments were affected by oxidative degradation either during its first life cycle or during the purification and regeneration processes. The fibres reclaimed from indigo dyed waste denim revealed presence of traces of dyes on the surfaceenCottonRegenerate fibresWaste garmentsCelluloseXPSConference Proceedings
