Chitosan‐assisted dyeing of cotton with sodium copper chlorophyllin: Effects of process parameters on colour yield and fastness

Abstract Sodium copper chlorophyllin (SCC), a food‐grade green pigment, offers potential for sustainable textile coloration; however, its application to cotton is hindered by electrostatic repulsion with the negatively charged cellulose surface. In this study, chitosan was used t...
