application features：with acid buffer optimization effect, it is used to control ph fluctuations in dyeing baths such as polyester/cellulose fiber fabrics, ensuring a successful dyeing once and improving dyeing reproducibility.
application features：excellent acid buffering capacity, used to adjust the ph value of the dyeing bath of polyester and blended fabrics, ensuring ph=4.5-5.0, with chelating dispersibility, and improving dyeing reproducibility
application features：protect the disperse dyes in the high temperature dyeing bath from being reduced by reducing substances, effectively improving the dyeing success rate and reproducibility of disperse dyes (especially for blue and cyan dyes)
