AVCO-LEV VAT

AVCO-LEV VAT

Rainbow is Avco preferable colour!

An anionic levelling agent with dispersing properties, for dyeing vat dyes in high liquor ratio dyeing machines and in continuous vat dyeing processes. Warp stripes and affinity differences between cottons of different origins are largely or completely covered.

Properties & uses:

  • Improves the levelling properties of vat dyes. Warp stripes and affinity differences between cottons of different origins are largely or completely covered
  • In the case of dense woven fabrics, excellent dye penetration is achieved with the product. In particularly difficult cases, the effect can be assisted by raising the temperature to 70-80°C and somewhat prolonging the dyeing time
  • Because it has no stripping action, the product permits faulty dyeing to be levelled with only a very small addition of dye to the blind vat
  • Performs well not only in exhaust dyeing but also in pad-steam dyeing. Addition of this product to the Caustic-Soda/Hydrosulfite reducing liquor accelerates dye vatting in the steamer, and so ensures complete vatting and fixation even with relatively short steaming times
  • Has a stabilizing effect on shade consistency during the steaming phase. It largely prevents shade changes due to temperature variations in the steamer or to the use of excessive or insufficient amounts of reducing agent

Ionicity:

  • Anionic
