This additive is a buffer for pH stabilization, an anti-reducing agent, and a chelating agent
Function of this auxiliary: (dosage: 2.0g/l+HAc 1.0g/l).
● It has excellent pH buffering, and the dyeing of polyester can stabilize the pH=4.0±0.2 of the dyeing process, so that the dyeing reproducibility is optimized.
● Aiming at the problem that the alkali content of tatting polyester chemical fiber is removed by alkali bath and affects the reproducibility of dyeing, it can be completely improved.
● Especially for the pH sensitivity of disperse dyes with high washing fastness, it can be perfectly controlled and improved.
● Contains anti-reduction, for dyes susceptible to reducing chemicals such as lignin, it has the function of stabilizing hue.
● Contains metal blocking function to improve water quality and prevent color passivation.
