Index Color 5 Mangosteen Rind Extract (Garcinia Mangostana L.) For Silk Dyeing
This study was to explore and extract the color from the fresh rind of mangosteen Index Color 5. The extract was
then applied on silk fabric to examine its dyebility. Freeze-drying methodology and mechanizable equipments have helped to
produce excellent colors of natural dye. The established dyes were experimented on silk fabrics via three types of mordanting
and dyeing procedures; pre-mordanting, simultaneous mordanting and post-mordanting. Silk fabric treated simultaneously
with mordanting and dyeing with Index Color 5’s dye produced a brilliant shade of red color and the color is also discovered
sensitive to light and washing during the fastness tests. The preliminary evaluation and instrumentation analysis allowed us to
examine whether the application of different mordanting and dyeing procedures with the same extract samples and
concentrations affected the colors and shades of the fabric samples.
