Abstract : Ecoprinting is an environmentally friendly printing technique used in the textile industry that utilizes plant-based dyes. Ecoprinted products often lack vibrant color because some natural dyes lack the active groups necessary to form chemical bonds with fabric fibers. Consequently, a mordant is required to facilitate bonding between the natural dye and the fibers. This study investigated the effects of chitosan mordant concentration and mordanting duration on ecoprinted fabrics dyed with teak leaves. Color intensity was evaluated both visually and using a chromameter. The results demonstrated that the chitosan mordanting process enhances color intensity and improves the definition of the teak leaf patterns. Optimal mordanting conditions were achieved with a chitosan concentration of 0.3% and a mordanting time of one hour. FTIR analysis revealed interactions between the active groups of the chitosan and the active groups of the fibers and dye pigments within the ecoprinted fabric.
