|
|
|
|
ENCEE POBS is a specialty non-silicate
stabilizer for Hydrogen Peroxide bleaching liquors to regulate the
rate of release of oxygen for optimal whites on cellulose material
and for savings in the consumption of peroxide. |

| Type |
: |
Anionic |
|
Appearance |
: |
Pale
Yellow Liquid |
|
Solubility |
: |
Soluble
in water in all proportions |
|
Compatibility |
: |
Stable
to hard water and alkali, compatible with anionic and nonionic
auxiliaries |
|
|
|
-
Controls the decay rate of Hydrogen
Peroxide in bleaching baths for optimum bleaching without the use of
conventional Sodium Silicate
-
Avoids risk of damage / pin-holes due to
iron impurities
-
Enables a softer feel on fabric as
silicates are absent
-
Eliminates problems of scale build up in
bleaching machinery
-
May be used along with Sodium Silicate
wherever Silicate is found essential, as in the case of heavily seed
- contaminated cottons where Silicate - caustic soda action is
advantageous.

TYPICAL RECIPIES : |
|
Bleaching of cottons in kier - 1000 kg's
of woven cloth or hosiery is first desized if required and / or
chemicked and then piled wet into the kier. The peroxide bleach
liquor is prepared at 45 - 50°C
at pH 10 - 11 with |

in 2000 - 2500 litres water so that
total liquor (along with water carried over by the wet cloth) is
4000 liters. Bleaching is carried out for 5 -6 hours at 90 - 95°C.
Bleaching time can be reduced in case of pressure kiers where liquor
temperature 0f 105 - 110°C
are employed. After the treatment, the cloth is washed well and
neutralized. |
