| Summary: | 碩士 === 國立臺灣科技大學 === 高分子系 === 95 === In this study, a series of ortho ester surfactants has been prepared by the reaction of polyoxyethylenated stearyl ether that change the length (EO=7, 15, 20, 30) than with TPG and TEOF. The structure of the final products was confirmed by FT-IR, 1H-NMR and elemental analysis.
The experimental results showed that these surfactants exhibited excellent surface active properties including surface tension、forming、contact angle、emulsification ability and stabilized、fluorescence.
This research complex on the direct dyes-cotton dyeing system have been found that the presence of these surfactants in direct dyeing solution can retard or increase the rate of cotton dyeing depending on the formation of the disaggregated or more aggregated direct dyes in dye-surfactant system, the degree of aggregation of direct dyes influencing the rate of cotton dyeing.
