Nonionic Leveling Agent for Polyester
A polyethylene oxide (PEO)-based nonionic leveling agent designed for high-temperature disperse dye dyeing of polyester and polyester blends. It acts as a dye-bath dispersant and migration promoter, preventing dye aggregation and ensuring uniform shade at 130°C. Compatible with all disperse dye classes and suitable for jet, beam, and winch dyeing machines.
