This study was primarily conducted to compare the fresh and fermented Malatayum leaves dyestuff using indigenous mordants on cotton yarn. It aimed to determine the yield of the dyestuff as affected by the fresh and fermented Malatayum leaves using five different indigenous mordants, compared the absorptive capacity of the cotton fabric as affected by the fresh and fermented Malatayum leaves dye extracts and compare the color fastness of the cotton yarn as affected by the fresh and fermented Malatayum leaves dye extracts. Malatayum leaves were collected and prepared for eight weeks fermentation and extraction. Indigenous mordants such as vinegar, rust, gabi extract, ash and salt were selected and prepared to mix to the dyestuff produced in both fresh and fermented leaves. CRD [complete randomized design] was the experimental design used in this study. The dye yielding performance of fresh and fermented malatayum was significantly different. Fermented malatayum leaves produced more crude extract than fresh malatayum leaves. Among the mordants used salt showed the greatest dye yielding performance of both the fresh and fermented malatayum leaves. Nonetheless, native vinegar, gabi extract and salt has no significant difference with the crude extract produced as compared to rust and ash. Fermented dyestuff was significantly different from fresh malatayum dyestuff in terms of the absorptive capacity of the cotton yarn. The effect of mordant to the cotton yards was highly significant to vinegar, ash and salt as compared to gabi extract and rust. The color fastness of fermented malatayum dyestuff mixed with following mordants brought out the army green color (vinegar), battleship gray (rust), dim gray (gabi extract), chamoisse (ash) and (ecru salt) colors to the cotton yarn. Likewise, the fresh malatayum dyestuff gave desert sand and tan (vinegar), seal brown, follow and khaki (rust), fawn and tan (gabi extract), ecru and follow (ash) grollu and follow (salt).
