This study entitled, “Bangkal Bark Extract as Natural Dye and an Ion-Exchanger”, aimed
to provide a new source of natural textile dye that lessens the use of synthetic dyes which
harms the environment and human health. It focused on dye extraction of crude from the
bark of Bangkal tree and converted into powder form, and its residue was processed as
Ion Exchanger. Bangkal bark crude dye was applied into Satin and 100% Cotton, which
gave a brownish color effect on both fabrics. The dyed fabric undergone test of its
Colorfastness to Laundering, Colorfastness to Perspiration, and Colorfastness to Light.
The results showed that there was a slight change on colorfastness to laundering and
perspiration, while much change was noticed on colorfastness to light. On the other hand,
the Bangkal bark residue was determined to have a phenolic content of 3.826 mg GAE/g,
which proves its capability as another source of Ion-exchanger. The product’s
acceptability was evaluated with 20 professionals and non-professionals in terms of
product functionality, aesthetic, and saleability. It was rated with an overall mean of 4.79
with a descriptive rating as “Highly Acceptable”. This signifies that the product has high
possibility as another natural dye contributor and likely, as an Ion Exchanger.
