本實驗利用田口實驗規劃法，來探討界面活性劑在不同參數設定下包括：界面活性劑不同親水 基鏈長、界面活性劑濃度以及界面活性劑型態，透過染料相互作用之實驗，並利用L9直交表 計算出S/N比，計算出因子反應表及因子反應圖，期望用最少的實驗次數，找出分散染料在染 液中的最佳化條件。最後為了要驗證此最佳化條件在染著方面與染料粒徑分佈方面為效果最好 之組合，會利用最佳化條件來實驗，皆以I組合(親水基鏈長為15、界面活性劑濃度0.15wt%、 界面活性劑結構為單分子型態)為最佳染著效果與最佳粒徑分佈。

In this study, Taguchi experiment planning method to investigate the surfactant at different parameter settings include: surfactants of different hydrophilic group chain length, concentration, and surfactant types, through the interaction of the dye experiment and use L9 orthogonal table calculation the S/N ratio, to calculate the factor reaction table, it is desirable to use the least number of experiments to find the best conditions in the disperse bath. Finally, in order to verify the best conditions in terms of distribution of dye-stained particle size and the combination of the best results, take advantage of the best conditions to experiment, I begin with a combination of (hydrophilic group chain length of 15, surfactants concentration of 0.15wt%, surfactant structure monomolecular patterns) for optimum effect dyed with optimum particle size distribution.
