Fig. 2: Acid hydrolysis of 44/56 polycotton waste textiles.
From: Polycotton waste textile recycling by sequential hydrolysis and glycolysis
a Glucose yield after hydrochloric acid (HCl) hydrolysis (50 mg/mL, 1000 rpm) of waste textiles over time in days (d). Shown values are averaged from three measurements and the error bars indicate the standard deviation. b 5-(Hydroxymethyl)furfural (HMF) yield after HCl hydrolysis (50 mg/mL, 1000 rpm) of waste textile over time in days (d). Shown values are averaged from three measurements and the error bars indicate the standard deviation. c TGA result of the residual waste textile after hydrolysis with 43 wt% aq. HCl for 1–4 days (heating rate 2.5 °C/min under N2 flow). All 12 measured samples showed only one decrease in mass and were identical to one another. d DTG result of the residual waste textile after hydrolysis with 43 wt% aq. HCl for 1–4 days (heating rate 2.5 °C/min under N2 flow). The peak corresponds to polyester degradation.
