AVCO-CID LPH

AVCO-CID LPH

Rainbow is Avco preferable colour!

An acid donor which evenly and slowly hydrolizes in hot aqueous solution to produce an organic acid, which lowers the pH of the solution down to 4.0-5.5 according to the concentration in the liquor. This slow dissociation process is useful for dyeing wool and polyamide fibers, as the dyes are exhausted very evenly and produce level dyed yarns and fabrics.

Properties & uses:

  • An acid donor which evenly and slowly hydrolizes in hot aqueous solution to produce an organic acid.
  • During the hydrolizing process the organic acid produced is lowering the pH of the solution down to 4.0-5.5 according to the concentration in the liquor.
  • The rate of the dissociation is slow in cold solutions and increases when the temperature is raised.
  • This manner of pH control makes it useful for dyeing wool and polyamide with acid and metal complex dyes. As the exhaution rate of acid dyes is pH dependent, the slow lowering of the pH in a dyeing solution containing the product, ensures more level dyeing, due to slower exhaution rate of the dyestuffs onto the fibres.
  • Recommended for even dyeing of polyamide, wool and blends of these fibres.
  • Does not influence any of the fastness properties of the dyed fibres.

Ionicity:

  • Nonionic
