Levelling agent for dyeings with disperse dyes, dispersing agent for oligomers
PERIGEN BIT is used as levelling agent for polyester and polyester blends.
For dispersing oligomers the product is used when dyeing as well as in the reductive cleaning.
PERIGEN BIT is a highly effective dispersing, migration and levelling agent for disperse dyes. The product enhances the dispersion of the dyestuff molecules and supports the migration of the dyestuffs. These migration supporting effects benefit in case of dyeings at high temperature.
PERIGEN BIT is dispersing oligomers and avoids filtration on the fabric and on yarn cones. Oligomers are kept in dispersion and do not precipitate during the cooling of the dye-bath.
