Nestogen - RDL | Dyeing Aid For Reactive

• Product Information

  Nestogen - RDL is a special formulation for dyeing of reactive dyes and vat dyes by exhaust as well as pad application. Nestogen - RDL improves the solubility of reactive dyes under adverse conditions of dyeings such as low liquor ratio, poor quality of salt, hardness in water, poor solubility of dyestuff.

• Key Features & Benefits

  • Solubilizing action prevents precipitation of low solubility reactive dyes at low MLR.
  • Uneven dyeing with incompatible dyes can be minimized.
  • Can be added in padding.
  • Improves dyebath stability and application uniformity of dyeings.
  • Does not affect color value or tone.
  • Recipe correction is not required.
  • Low foaming.
  • Suitable for jet and package dyeing.

• General Characteristics

  • Physical appearance: Clear to turbid brownish liquid
  • Ionic nature: Anionic
  • Miscibility: Miscible with water
  • Compatibility: Compatible with anionic and non-ionic products
  • Stability: Stable to dilute acids, dilute alkalies

   

   

• Application

  1. Exhaust process:

     • 0.5 - 2 g/l Nestogen - RDL (Concentration to be added depending on dyestuff and depth of shade).

  2. Continuous dyeing:

     • 3 - 6 g/l Nestogen - RDL is recommended in the pad liquor for uniformity of the dyeing as well as good bath stability.

  3. Grey dyeing of cotton yarn & knits in medium and dark shades with reactive dyes:

     • 0.5 - 1.0 g/l Nestodet-R
     • 0.3 - 0.5 g/l Nestoquest-W
     • Treat at 85°C for 15-20 min, cool the bath below the required dyeing temperature,
     • Add 1 g/l Nestogen - RDL,
     • Circulate for 5 mins and carry out isothermal dyeing as recommended by dyestuff manufacturer.

  4. Dyeing of Bleached Yarn in package form:

     • 0.5 - 0.7% Nestogen - RDL for regular dyes,
     • 1 - 1.2% Nestogen - RDL for critical & poor solubility dyes.

  5. Print Paste:

     • 0.3-0.5% Nestogen - RDL.

• Advantage

  Nestogen - RDL act as a solubilising and levelling agent particularly for bath dyeing. It does not affect colour value or tone. Nestogen - RDL can also be added in print paste to obtain brighter and uniform print.

• other Information

  For all above processes half quantity of Nestogen - RDL to be added during dissolving of the dyestuffs
  and balance quantity to be added in the dyebath / padding liquor.
