Fiber-affinity‌: Provides moderate dyeing retardation.‌Dye-affinity‌: Offers controlled retarding effects to suppress initial strike rate during dyeing.‌Exceptional dispersion‌, solubilization, and protective colloid effects, preventing dye agglomeration at high temperatures. Enhances dye migration for improved dyeing performance. Delivers superior leveling and penetration for dyes.‌Compatible‌ with carriers, anionic dispersants, lubricants, and scouring/dyeing auxiliaries in dye baths. Chelates metal ions to eliminate their adverse effects on dyeing.‌Applicable‌ to natural fibers and blends with synthetic fibers. Stable across temperature ranges, including high temperatures, without fiber adsorption or dye precipitation. Imparts softness, fullness, and uniform appearance free from stains or streaks.‌Highly soluble‌ in hot water, low-foaming, suitable for jet/overflow dyeing machines.‌Improves fiber smoothness‌, mitigates density-related shrinkage issues, and enhances carding/spinning efficiency post-dyeing for loose fibers.
