» POLYCOL – OS (Organic Stabilizer for Peroxide)
exporter textile chemicals
POLYCOL-OS is a very effective organic stabiliser for Peroxide bleaching process. It is preferable to conventional silicate based stabiliser, due to its obvious advantages.
» APPEARANCEexporter textile chemicals: Pale Brown Liquid.
» IONIC NATUREexporter textile chemicals: Anionic.
» SOLUBILITYexporter textile chemicals: Soluble in water in all proportions.
» COMPATIBILITYexporter textile chemicals: Compatible with Nonionic / Anionic Auxiliaries.
» By proper stabilization of hydrogen peroxide, it produces high degree of white-exporter textile chemicalsness with minimum fiber damage.
» Lime Soap deposits are separated & dissolved.
» Heavy metal & metal ions are complexed.
» Lower & higher molecular weight degraded products of the cellulose are made exporter textile chemicalsremovable.

» POLYCOL – PKL (Peroxide Killer)
textile bleaching chemicals
POLYCOL-PKL is a ‘Special Agent’ or a Peroxide Killer that liquidates any peroxide present while exerting absolutely no effect on Reactive Dyestuffs. As a result, the use of POLYCOL-PKL ensures complete elimination of peroxide or peroxy compounds & ensures subsequent Reactive dyeing against risk of colour loss or unevenness even if added in excess.
When cottons are bleached with Hydrogen Peroxide, it becomes necessary to wash out all residual peroxide & peroxy compounds which are left in the cotton, if the material is to be subsequently dyed with Reactive dyes. In case of any peroxide getting carried into the dye bath, it affects the dyeing and causes in poor colour yield & uneven shade.
Several rinses may be required to ensure complete removal of peroxide. However, most processors give a short treatment with a reducing agent like Hydrosulphite or Bisulphite which destroys peroxides. Such treatment involves a major risk because if these reducing agents are used in excess, it may cause uneven dyeing.
» APPEARANCEtextile bleaching chemicals: Colourless to pale clear liquid.
» SOLUBILITYtextile bleaching chemicals: Readily soluble in water giving clear solution.
» pHtextile bleaching chemicals: 6 – 8.
» Nullifies totally residual peroxide used during pretreatment & helps for uniform textile bleaching chemicalsdyeing.
» Does not interfere with subsequent reactive dyeing even if used in excess.
It is important to note that POLYCOL-PKL is best utilised in alkaline conditions & at a temperatures above 70°C. It is therefore recommended that after the peroxide bath has been drained at the end of the bleaching process, POLYCOL-PKL is added in the rinse bath maintained at 70 – 75°C (the pH would be alkaline due to residual alkali from the bleach-bath) & run for 10-15min. to quench all peroxide. In fresh bath, any alkali present may be neutralised by addition of suitable acid to maintain the pH at 5 – 6 for the start of the Reacyive dyeing process at the required temperature.
