Industrial Applications in Bangladesh
Bangladesh Market Context: Crucial electrolyte in Bangladesh knit/woven dyeing mills (used at 30–80 g/L) to drive reactive and direct dyes from the dyebath onto cotton fibers without spotty calcium precipitation.
- Electrolyte exhausting agent in cotton reactive, direct, and sulphur dyeing baths
- Free-flowing carrier and ionic strength builder in synthetic laundry detergent powders
- Fining agent to remove micro-bubbles in molten glass and kraft pulp cooking liquor makeup
