The natural dye source is environmentally friendly and stays on the fabric permanently. The study aimed to develop and evaluate the dyestuff from Acacia Branches dyestuff, determine the color value, evaluate the colorfastness to washing, sunlight, and perspiration, and determine the significant differences in mordant used (alum, copper sulfate) and boiling time (60 minutes - 30 minutes, 60 minutes - 60 minutes). The study utilized the developmental-descriptive-evaluative research design. The statistical tool used was the weighted mean. Questionnaire was used in colorfastness properties. Mobile application (Grab Color) was used to determine color value. Findings shows that the color value of the dyed royal poplin and linen fabrics yielded light color. The evaluation of the colorfastness to washing, sunlight, and perspiration was good performance and there was no significant difference existed in terms of mordant used.xiii, 79 p.: ill.
