LUBIGAN, ARABELLE C., Applied Research IV (General Science Curriculum), Laboratory School, Cavite State University, Indang, Cavite, April 1999. “UTILIZATION OF BIGNAI (Antidesma bunius Linn. Spreng) AS DYE” Adviser: Emil L. Escalante

In order to know the dyeing potential of bignai, this study entitled “Utilization of Bignai (Antidesma bunius Linn Spreng) as Dye” was conducted with the following objectives: (a) utilize bignai to produce dye through manual operation; (b) compare the efficiency of the produced dye to the commercial dye based on fastness to light and fastness to wash on textiles such as cotton, silk and synthetic; and (c) analyze the chemical composition of bignai.

The study used four treatments three of which are bignai solutions: T1 (90 mL bignai + 90 mL water), T2 ( 90 mL bignai + 180 mL water) and T3 (i80 mL bignai); and a Control Treatment (commercial dye), which serves as the basis of comparison.

In order to determine the effectiveness of the treatments, the dyed textiles were subjected to the light fastness and wash fastness test.

The physical properties of the textiles were evaluated by 50 panelists based on their fastness, odor and general acceptability. The statistical tools that were used in analyzing the data are three-way Analysis of Variance and

Duncan's Multiple Range Test (DMRT).

Analysis of the mean scores shows that Control Treatment (commercial dye) was found to be superior to the other treatments in terms of fastness in all the textiles (cotton, silk and synthetic).

The result also showed that there are significant differences in the interaction between the treatments and the textiles on odor of dye. However, Control Treatment is still highly superior to all other treatments.

Mean scores for general acceptability of dye on the different textiles revealed that Control Treatment gained the highest mean score on the textiles (cotton, silk and synthetic).
