In this study, the relationship between the synthesis of a series of polyethylene glycol derivatives Gemini surfactant with disperse dye, the first use of UV-vis spectroscopy to study the interaction of the dye synthesized product, and the product combined with the dye particle size, the product is used dyeing of polyester dyeing test, understand the impact of this series of products for the disperse dye polyester. Found by test results for this series of synthesis products are surfactant helps disperse the dye in a dyebath nature.
