Abstract—Problem statement: Traditionally the dyeing of
natural dyes from plant materials was done by boiling using
roaches method which requires longer time, higher temperature
and metallic mordant to get good color fastness. Metallic
mordants usually used in dyeing posed some serious bad effect to
ecological. Thus this study explored a suitable technique for
more efficient natural dyeing using suitable bio mordant to
improve the color fastness of natural dyes on silk fabric.
Approach: This study demonstrated ultrasonic cleaner as a
technique of dyeing the colorant from a selected plant, i.e
Xylocarpus moluccensis to a selected fabric, i.e silk. Colorant
from combination of heartwood and bark (as a biomordant) of
Xylocarpus moluccensis was dyed at different ultrasonic volume
and time. Result: Results show the highest percentage of dye
absorbed to silk fabric using ultrasonic cleaner was produced at
optimum condition of medium sonic volume in 80 minutes time.
Bark of Xylocarpus moluccensis was used as the biomordant to
produce good color fastness properties to washing and
perspiration. Conclusion: The utilization of ultrasonic cleaner
and biomordant was found to have significant improvement in
the dyeing color of natural dyes to silk fabric with lower dyeing
temperature compared to traditional roaches method.
