Abstract

•CA firstly forms aconitic acid before forming anhydrides under elevated temperature.•H2O2 can improve the whiteness of CA–treated fabrics via Michael addition reaction.•H2O2 bleaching of CA–treated fabrics is a more kinetically controlled reaction.•Yellowing problem is reduced under proper pH, short bleach time and high temperature.
