Dispersing and levelling agent for high temperature dyeings of polyester
PERIGEN SEF is preferably used for the dyeing of polyester and polyester blends on cheese dyeing or beam dyeing systems.
In addition PERIGEN SEF can be used on HT-jet dyeing machines as dispersing and levelling agent.
PERIGEN SEF has excellent dispersing and levelling properties. In polyester dyeing the product avoids filtration of dyes even with critical disperse dyes.
Besides the classical dyeing in the slightly acid medium PERIGEN SEF is also very well suitable for the alkaline dyeing of polyester. In addition to an optimal dye yield the reproducibility of dyeings is excellent.
PERIGEN SEF is perfectly suitable for the optical brightening of polyester at HT conditions.
