Possesses excellent restraining and migrating properties, thereby imparting superior levelling effects with pre-metalized dyes, i.e. MODERSET® series.
Leveling agent for dyeing wool with MODERSET® dyes in the iso-electric region of the wool at pH 4.5-5 with minimum loss of wool quality. Improves fiber and surface levelness. Promotes migration, diffusion and in-tone build-up of dyestuff combinations.
Its surfactant properties provide a useful degree of dye penetration for use on hard twist yarns.
It is easily handled and can be added directly to the dyebath.
Also suitable for dyeing pre-metalized dyes on polyamide fibers.
