Application of natural dye from pomegranate (Punica Granatum) skin on cotton fabric treated with chitosan / Nurulhazwani Sulaiman

In this study, the application of pomegranate skins as natural dye on chitosan treated cotton fabric was examined. Two dye extraction methods were used namely boiling and solvent extraction. Solvent extraction gave darker brown shade compared to boiling. Application of chitosan was done using paddin...
