SARAQUEST-W

Saraquest-W | Sequestering Agent

Product Information

Saraquest-W is 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, magnessium 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.

Application
  1. In scouring, bleaching as well as combined scouring and bleaching of cotton and blends by batch process:

    0.5-1 g/l Saraquest-W can be added with usual recipe to prevent white deposits as well as pin-hole marks due to iron. When Saraquest-W 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
    0.5-1 gm/kg Saraquest-W is recommended
  3. In bio scouring of cotton

    0.3-0.5% Saraquest-W 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 Saraquest-W is added before bleaching.

Note : Please note that for dosing, 10% dilution of Saraquest-W is recommended instead of neat solution.

Precautions

Storage : Store in cool, ventilated shed away from heat and direct sunlight.Storage temperature should not exceed 35 deg C.Close lids firmly to avoid contact with air and moisture.
