Nestolev – DA – DLP | Migration Based Levelling Agent

• Product Information

  Nestolev – DA – DLP is a non-staining levelling agent based on migration. No cloud point  effect and compatible with the most commonly used  polyester dyeing  auxiliaries.

• Key Features & Benefits

  • Improves migration of even the most difficult, high molecular size disperse dyestuffs.
  • No restraining action on exhaustion of disperse dyes, full yields are obtained in deep shades.
  • Helps compensate for lack of compatibility of dyes in mixtures, used because of economy or particular fastness properties.
  • Anionic chemical nature ensures compatibility with all commonly used polyester dyeing auxiliaries. No cloud point effect.
  • No carrier content, no formaldehyde content, no anti-foam content.
  • Low viscosity suitable for liquid dispensing.

• General Characteristics

  • Appearance: Clear Yellow Brown Liquid
  • Nature: Anionic
  • Composition: Proprietary anionic compound
  • Solubility: Readily soluble in water
  • Stability to hard water: Good
  • pH: 6.5 ± 1

• Application

  [ I ]. NestoLev- DA-DLP used as levelling agent in dyeing of Polyester: NestoLev DA-DLP is suitable for use on all types of high temp. dyeing machinery. After scouring the goods, the dye bath is set with fresh water, and the temperature is raised to 60°C.

  • NestoLev DA-DLP: 0.5 to 1.0 gpl
  • Proton AH – 6*: 1.0 to 1.25 gpl
  • Disperse Dyes: X% (O. W. F.) [*Possesses buffering, sequestering, and dispersing action]
  • Add NestoLev- DA-DLP to the bath together with other required chemicals and circulate.
  • Adjust the pH to 4.5 to 5.5.
  • Add pre-dispersed dyestuffs, preferably through a sieve or filter.
  • Raise the temperature from 60°C to the maximum dyeing temperature (130-135°C) at the desired temperature gradient.
  • Rapid rates of rise of 2-4°C per minute are possible.
  • Run for 30-60 minutes.
  • Cool to a temperature at which the liquor can be safely drained without causing creasing, then rinse or perform reduction clearing if necessary.

  [ II ]. NestoLev- DA-DLP used for re-leveling of faulty dyeing of Polyester: NestoLev DA-DLP can be used to correct unlevel dyeing or reduce the depth of dyeing that was dyed too heavily.

  • Treat for 45-60 minutes with NestoLev DA-DLP: 2 to 5 gpl.
  • At the maximum dyeing temperature, this treatment will hold the dye removed in the bath.
  • If shade correction is necessary, these should be carried out after first replacing all or most of the bath.
  • Re-leveling treatments should be followed by thorough rinsing and reduction clearing to ensure maximum fastness.
