Industrial Applications in Bangladesh
Bangladesh Market Context: Essential mild alkali in textile reactive printing (prevents premature dye hydrolysis during drying prior to steaming) and chrome-tanned wet-blue leather neutralization.
- Mild alkali donor in reactive dye printing pastes for cotton and viscose fabrics
- Uniform pH neutralization of chrome-tanned leather (wet blue) in Savar tanneries
- Flue-gas desulfurization, fire extinguisher dry powder, and detergent formulation
