  3. Keeps unfixed dyes in water dispersion, and prevents staining of white and
    colored grounds of the printed fabrics.
  4. Pruduces clear and bright shades, with better rubbing and washing fastness.
  5. While printing polyester blends with cellulosic fibres, AVCO-LEVOLUZE WPE keeps
    disperse dyes from staining the cellulosic fibres.
  6. The product contians complexing and dispersing agents which prevents
    precipitation of thickeners and dyestuffs residues due to interaction with water
    hardness.
  7. Liquid product which can be dosed as is.
