Acid dyes fixing agent FNR
Main composition
-- Sulphonate condensation polymer.
General properties
-- Appearance: red brown liquid

Properties and fields of application
-- Tarnally similar appearance as the best two acid dye fixing agents in Germany, as well as technical specification.
- Especially for wool, nylon, silk and leather with anionic dyestuffs (acid/metal complex dyestuffs) while washing,
perspiration, light, chlorine and bleeding fastness can be sharply improved after treatment.
-- Excellent dye fixing performance on nylon webbing that is obviously better than other acid dye fixing agents.
-- Slight influence on shades and hand feels that can use in the same bath of dyeing and fixing, which shortens process.
-- Outstanding acid resistance for easy operation.
