Acid dyes fixing agent FNR
Main composition -- Sulphonate condensation polymer. General properties -- Appearance: red brown liquid -- Ionicity: anionic -- pH: 3.5-4.5 -- Solubility: easily soluble in water -- Stability: stable to acid, alkali, electrolytes and hard water 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. Application -- Dye fixing of fabrics with acid/metal complex dyestuffs. Pale shades: 1-2% (o.w.f) Medium shades: 2-3% (o.w.f) Deep shades: 3-4% (o.w.f) Bath ratio: 1: 10-15 Temperature & time: 80℃× 20 min Packing and storage -- Packing: 125 kg/polyethylene drum -- Storage: 6 months in sealed container at room temperature |
