The hypothesis of this study is that the
cotton fabric treated with chitosan should
show an increase in the dye sites for
attaching dye molecules to the fabric over
the untreated fabrics. The study focuses
on the effect of chitosan on the dyeing
properties of cotton fabric with dye filtrate
extracted from Mangosteen Rind. In
addition, this study is also to investigates
the fastness properties, shade and depths
of shade as affect by three different
methods of dyeing, i.e. pre-mordanting,
meta-mordanting and post-mordanting.
