Application of persimmon (Diospyros kaki L.) peel extract in indigo dyeing as an eco-friendly alternative reductant
Abstract The aim of this study is to investigate the efficacy of persimmon (Diospyros kaki L.) peel extract as a reductant for indigo dyeing. Dried persimmon peel was water extracted and its sugar contents and functionalities were determined. Its reducing power was studied in terms of redox potentia...

Its reducing power was studied in terms of redox potential of the indigo bath and color strength (K/S value) of the ramie fabrics dyed in the indigo reduction bath.
