The low fixation rate and colorfastness of natural dyes limit their practical application in modern textile coloration. Further, hazardous mordants are used in conventional natural dyeing to achieve better fixation and colorfastness. Herein, a green, sustainable, and environmental benign fixation process of natural dye was developed using a non-aqueous medium in the absence of mordants… Continue reading Green and Sustainable Method to Improve Fixation of a Natural Functional Dye onto Cotton Fabric Using Cationic Dye-Fixing Agent/D5 Microemulsion

Abstract: Natural dyes exhibit a low dye uptake when cellulosic fiber dyeing is carried out using a conventional water bath dyeing process. In this research, cotton fabric was exhaust dyed in a microemulsion dyebath containing cacao husk extracts dye and decamethylcyclopentasiloxane (D5) to achieve higher dye exhaustion percentage on cotton fiber, which is an environmentally… Continue reading Adsorption, kinetics, and thermodynamic studies of cacao husk extracts in waterless sustainable dyeing of cotton fabric
