This research aims to explore eco-friendly dyeing methods for cotton fabric using a natural dye and bioproducts as mordants.
Utilized alkaline extraction of dye from achiote seeds at 85°C for 2 hours.
Conducted dyeing trials on cotton fabric with glycine max protein extract as a mordant.
Measured color strength and fastness characteristics for evaluation.
Achieved a maximum crude dye yield of 25%.
Demonstrated optimum color strength (K/S) of 5.18.
Exhibited reliable color fastness characteristics in the dyed fabrics.
