Product	Properties, applications
Meropan DY Meropan DG Meropan DB Meropan DA	Sequestering and dispersing agents for cotton dyeings with reactive and direct dyes, they are able to eliminate all possible negative influences due to water hardness on dyeing, particularly to prevent formation of calcium carbonate and colour stains during dyeing. In soaping off reactive dyeing, they facilitate the removal of unfixed dye and prevent their redeposition onto the fibre. In washing off of multi - coloured articles they prevent cross - staining.

Meropan RED	Reducing agent for reduction clearing subsequent to PES dyeing, Meropan RED is effective in acidic medium and often used in reductive washing-off of polyester, polyacrylonitrile and their blends. Go to top
Meropan EF	pH-controller for polyamide dyeings, special ester, Meropan EF will be slowly and evenly saponified to an acid in the dyebath during the heating and boiling stage of dyeing, consequently the pH of the dyebath will be gradually changed to acidic. As a result, the rate of absorption and the degree of final exhaustion could be regulated through changes of pH in the dyebath. Level dyeings could be, therefore, more easily obtained just by slowly changing the pH of the dyebath from slightly alkaline to acidic. Go to top
