Fiber-affinity‌: Provides moderate dye-retarding effects; resistant to acid, alkali, and hard water.‌Dye-affinity‌: Offers controlled retarding effects. The moderate retarding property suppresses initial strike rate during dyeing, enabling exceptional leveling through retardation.‌Superior dispersion‌ and anti-aggregation properties, preventing dye coagulation that may cause specks, stains, or streaks. Enhances solubilization, dispersion, and protective colloid effects for acid dyes, promoting leveling.‌Chelates metal ions‌ in dye baths to eliminate their adverse effects on dyeing.‌Compatible‌ with anionic dispersants, lubricants, and other auxiliaries in dye baths.‌Improves fabric handfeel‌: Polymers impart softness, fullness, and smoothness.‌Excellent penetration aid‌, ensuring uniform dye penetration.‌Highly soluble‌ in hot water, low-foaming, suitable for jet/overflow dyeing machines.
