本研究利用soy protein與不同氧乙烯鏈長之polyoxyethylenated stearyl ether及dextrin反應，製備一系列具大豆蛋白衍生物構造之高分子型界面活性劑。合成物以FT-IR、1H-NMR及EA進行確認其結構。並測試其基本性質包括表面張力、起泡性、濕潤性、乳化作用、螢光性質等，並測試其精練、漂白及染色性等的應用性質。
由實驗結果顯示，所製備之大豆蛋白衍生物具有界面活性且氧乙烯鏈長在0~30之間，隨著構造中氧乙烯鏈長的增長，其表面張力隨之增加，接觸角皆比純水小，並具有較高之起泡性，而且乳化物之粒徑大小幾乎不隨時間的增加而改變，其粒徑為5 μm以下，界面電位也隨著氧乙烯鏈長的增長而增加，表示具有良好的乳化品質及穩定性。應用在棉胚布的精練、漂白等前處理過程中，可增進精練漂白的效果，且作為酸性染料染尼龍織物的染色助劑，亦具有緩染效果。

In this study, a series of polymeric surfactant is prepared by the reaction of soy protein, polyoxyethylenated stearyl ether and dextrin. The structures of these products were conformed by the measurement of FT-IR, 1H-NMR and EA analyses. The fundamental properties containing surface tension, foaming, wetting, emulsion, and fluorescence properties and application for scouring, bleaching and dyeing of surfactants have been evaluated.
From the results, the good properties including surface tension, foaming and wetting properties were found. The surface tension increase with the increase of polyoxyethylene length in structure. The emulsified oil particles were found below 5 μm and almost independent of the time changes. Zeta potential decrease with the increase of polyoxyethylene length of surfactants.
In application, it presents good effect on cotton scouring bleaching, and in nylon-acid dyes system, they present a retarding effect.
