Industrial Applications in Bangladesh
Bangladesh Market Context: Sourcing 60%–75% concentrated mother liquors directly from China allows Bangladesh mills and chemical houses to cut freight and packaging costs by 65% compared to importing diluted drums.
- Formaldehyde-Free Fixing Agent: Elevates wet rubbing, washing, and perspiration fastness of deep red/black/turquoise reactive dyes to Grade 4–4.5
- Silicate-Free Peroxide Stabilizer: Controls H2O2 decomposition rate without hard silicate scale buildup on dyeing rollers
- Soaping-Off Agent: Strips unfixed hydrolyzed reactive dyes in 1 bath at 90–95°C without staining white stripes
