PARAKOL-YS |

Dyebath conditioner and washing off agent

Parakol-YS is an economical concentrated polymeric compound which is used as a dyebath conditioner and washing off agent. Calcium and Magnesium impurities in the dyebath lead to precipitation of dyes as well as poor washing off of hydrolyzed dyes at the end of dyeing. Due to its chelating action, Parakol-YS prevents such precipitation and also helps in easy removal of hydrolyzed reactive dyes at the end of dyeing operation. Parakol-YS is recommended as a washing off agent for reactive dyes in batch operation as well as in continuous operation.

Dye bath conditioner

1. Dye bath conditioner
   0.15-0.3% Parakol-YS is added to the bath before addition of dyestuffs or chemicals. A quantity of Parakol-YS would depend upon liquor ratio, quality of process water, quality of salt and efficiency of scouring operation as well as concentration and solubility of the dyestuffs used in the recipe.
   
   
2. Washing off by Batch Operation in Jigger
   0.15-0.3 g/l Parakol-YS
   0.1-0.2 g/l Kalium-NNS (Conc) (optional)
   pH adjusted to 7, Residual salt concentration should be less than 2 g/l before soaping.
   
   Carry out soaping at 85-95 deg.C for 10-30 min., hot wash, cold wash, neutralise. Repeat soaping in a fresh bath for dark and problematic shades. Carry out fixation for dark and problematic shades.
   
   
3. 0.3-0.6 g/l Parakol-YS OR 1.0 g/l Parakol-YS (after dilution 1:3)

Note : Product is hygroscopic, so container to be closed properly after use.

Instructions For Dilution

Instructions For Dilution

• Take 70 parts of DM water
• To this, gradually add 30 parts of Parakol-YS under constant stirring at 500-600 rpm using a paddle stirrer to obtain clear homogeneous liquid.

Preservation: It is recommended to add 0.1% Bronopol (2-Bromo,2-nitropropane, 1,3-diol) or Methyl Paraben (methyl para hydroxy benzoate) as an antimicrobial agent to avoid fungal/microbial growth.

• In order to carry out dilution of Parakol-YS faster, 60 deg.C DM water may be used.
• pH of final dilution should be maintained at 7-7.5.
• The diluted product will be colourless to light brown liquid.
• Un-dissolved particles if any can be filtered off.

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.

Shelf Life : 9 months from the date of manufacturing, if stored under controlled conditions.
