pH Stabilization‌: Maintains dye bath pH at ~9 (measured by pH meter) throughout the process, preventing polyester oligomer deposition (90+% removal rate) and associated defects like white powder or speckles.‌Process Simplification‌: For polyester/cotton blends, enables combined scouring/dyeing in one bath, eliminating pre-bleaching and reducing water/energy consumption.‌Leveling & Dispersion‌: Compensates for uneven pretreatment, allows omission of acid washing for T/C or T/R fabrics, and supports combined pretreatment/dyeing processes.‌Color Enhancement‌: Produces brighter shades than acid dyeing, with superior dispersion/leveling and minimal batch-to-batch variation (higher first-time success rate).‌Energy Savings‌: Shortens dyeing cycles, reduces reduction cleaning, decreases equipment cleaning frequency, and lowers utility costs (water/steam/electricity).‌Water Conservation‌: Minimizes pre- and post-dyeing rinses.‌Softening Effect‌: Eliminates need for anti-creasing agents during dyeing while delivering softer, smoother handfeel and easier post-dyeing rinsing.
