Quest-HP is an organophosphonate (HEDP) based high power sequestering agent specially developed for scouring as well as bleaching of cotton, terry towel and polyester/cellulosic blends. It has a high chelating action for calcium, magnesium and iron under alkaline conditions and high temperature. It not only prevents precipitation of insoluble hydroxides and carbonates formed during scouring and bleaching, but also chelates iron impurities thereby preventing catalytic damage and pin-hole marks during peroxide bleaching. It is also suitable for combine scouring and bleaching operation.
|High chelation value for calcium and iron
|Suitable for processing with hard water and with high iron content
|Good sequestering action over wide pH
|Nonionic to weakly anionic
|pH of 1% solution
|2 +/- 1
|Miscible with water
|Compatible with nonionic and anionic products
|Stable to dilute acids, dilute alkalies and hard water
1. In scouring, bleaching as well as combined scouring and bleaching of cotton and blends by batch process:
0.5-1 g/l Quest-HP can be added with usual recipe to prevent
white deposits as well as pin-hole marks due to iron. When
Quest-HP is added in the recipe, reduces the concentration of
organic stabiliser as it has stabilising action.
2. For combined scouring and bleaching on continuous bleaching range
3. In bioscouring of cotton
0.3-0.5% Quest-HP is recommended to prevent precipitation of pectin residues at the end of bio-scouring and before peroxide bleaching. Quantity of peroxide stabiliser can be reduced when Quest-HP is added before bleaching.
Please note that for dosing, 10% dilution of Quest-HP is recommended instead of neat solution.
