Use:
It is mainly used to dye cotton fibre .The pop "cowboy" clothes mostly are made by indigo blue dying longitudinal yarn and white
yarn interweaving;It can be used with sulfurated coloring matter;Also we can get indigo white,bromized indigo blue from it,
they are well used in food coloring matter, biochemistry etc.
Packages:
