From: Study on Fenton-based discoloration of reactive-dyed waste cotton prior to textile recycling
Plots of thermal analysis: TGA-plots of black-dyed cotton (a) and blue-dyed cotton (c) show the decrease in weight (%) (—) and weight derivative (---) during a temperature rise from 30 °C up to 500 °C for the dyed and Fenton-treated cotton. DSC-plots of black-dyed cotton (b) and blue-dyed cotton (d) show the heat-flow (W/g) during three heating/cooling cycles from − 25 up to 250 °C, for the dyed (—) and Fenton treated (---) cotton.
