Natural Dyeing of Modified Cotton Fabric with Cochineal Dye [PDF]

Molecules, 2022
Natural dyes are not harmful to the environment owing to their biodegradability. For dye application to textiles, salts are necessary as mordant or electrolytes and make an environmental impact. In this paper, the influence of cationization during mercerization to the dyeing of cotton fabric with natural dye from Dactylopius coccus was researched.
