摘要

現今科技越來越發達，在各領域上的實驗越來越複雜，相對的實驗成本與時間越來越高，本研究目的在運用田口方法於合成纖維製程的實驗上來降低實驗次數與提高實驗效率。以合成纖維之亞克力絲束熱延伸製程為例，應用田口式直交表進行實驗，藉由控制因子與水準之設定，評估其在亞克力絲束熱延伸製程中影響的重要性程度，並考量因子間的交互作用，使得實驗預測值之準確度提高，再將評估之實驗組合進行小範圍實驗，找出製程中可能的較佳參數組合，達到降低實驗成本的效果。
本研究考慮了因子間的交互作用，研究中預測結果比未考慮因子間交互作用之預測值準確度提升。經由實驗得知，考慮因子間交互作用之預測較準確，30次的實驗可與48次的實驗得到相同的實驗結果，節省至少288小時的實驗時間，並減少了18次實驗以上的實驗成本，經由此次實驗得知，田口方法有效的提升實驗效率、降低實驗成本，可以藉此提供合成纖維製造工廠之其他製程實驗之參考。

Now technology is increasingly developed, experiments in various domains are increasingly complex, thus relatively experimental cost and time used are increasingly getting higher, so the study aims at using Taguchi method applied to experiment for synthetic fiber process to reduce experiment times and enhance experimental efficiency. The study takes acrylic strand hot drawing process as example, applies Taguchi orthogonal table to experimental process, by means of setting control factors and levels, to evaluate their importance of effect in acrylic strand hot elongation process, and considering interaction effect among factors, so that accuracy of experimental prediction can be enhanced, and further conducts small range experiment with evaluated experimental combinations, to find out possible preferred parameter combinations in the process, thereby effect of reducing experimental cost can be achieved.
The study considers interaction effects among factors, the prediction results in the study has enhanced prediction accuracy comparing to that of interaction effects among factors not considered. From experiment, it is found that prediction with interaction effects among factors considered is more accurate, the same experimental results of 30 times of experiments are the same as results of 48 time, through the experiments, it is found that Taguchi method is capable of effectively enhancing experimental efficiency, reducing experiment cost, and thereby it can be provided for reference in experiments of other processes in synthetic fiber processing plants.
