Jiefa’s ES series sodium lignosulfonate is an high-performance dye dispersant engineered to set a new industry benchmark. Derived exclusively from sustainably pine wood, this lignin-based formulation is fully biodegradable and contains no APEO, quinoline or other hazardous by-products. As an industry leader, the ES series consistently outperforms competing American products such as 83A and 85A—providing textile processors with faster, more uniform dye uptake and a significantly wider working window.
Under lab testing, the ES series high-performance dye dispersant exhibits exceptional high-temperature dispersibility and outstanding thermal stability, maintaining uniform particle size distribution even at elevated dyeing temperatures. Its inherent stain-resistant properties minimize undesired shade variations and fiber damage, while its ultra-low foaming profile ensures smooth circulation in high-speed dyeing machines. Also, natural pine-derived aromatic note further distinguishes ES series, enhancing user comfort without masking process odors.
Globally recognized dyestuff manufacturers—including Dystar, Archroma, Colourtex, Flariant and many other industry leader—have integrated ES series into their specialty disperse and vat dye ranges, replacing traditional naphthalenesulfonate dispersants. This shift has been driven not only by ES series’s superior performance but also by its compliance with the EU’s stringent REACH regulations on chemical safety.
