Mercerization remains indispensable in textile dyeing for enhancing fabric luster, improving dye absorption, and stabilizing product dimensions. While conventional dilute mercerization lye recycling via evaporators suffers from contaminant accumulation degrading alkali quality, Keysino's proprietary alkali purification technology effectively removes contaminants through optimized recovery processes, delivering regenerated lye meeting operational standards for reuse in desizing, scouring, and mercerization cycles.
