Fiber-affinity‌: Moderate blocking effect; resistant to acid, alkali, and hard water.‌Dye-affinity‌: Moderate retarding effect. The controlled retardation suppresses initial strike rate, ensuring exceptional leveling.‌Excellent migration‌: Corrects uneven dyeing and color differences. Resists oligomer interference.‌Superior dispersion‌: Prevents dye agglomeration or precipitation, avoiding defects like specks, stains, or streaks. Enhances leveling by solubilizing, dispersing, and protecting acidic dyes. Chelates metal ions in the dye bath to prevent adverse effects.‌Compatibility‌: Non-interference with anionic dispersants, lubricants, or other auxiliaries.‌Softening effect‌: Polymers impart soft, full, and smooth hand feel to fabrics.‌Easy dissolution‌: Soluble in hot water; low-foaming, suitable for jet/overflow dyeing machines.‌Enhanced penetration‌: Promotes uniform dye penetration.
