Abstract:	T/OP混紡織物因彈性纖維在染著後易析出殘餘染料造成浮色，會對織物的染色堅牢度檢測造成影響。其耐水洗牢度品質控管，需求在3-4級以上。在生產過程中為使織物顏色及染色堅牢度皆達標準，會通過不同之還原洗工程，改變還原洗使用藥劑、洗淨次數以達到需求之染色堅牢度。本研究以黑色、紅色、寶藍色三種耐水洗牢度表現不穩定的顏色，以五種酸性和鹼性還原洗配方，分別做一次還原洗，比較五種配方的耐水洗牢度，從中擇出酸性及鹼性各一耐水洗牢度較佳之配方，再進行不同酸鹼洗次序之連續還原洗試驗。實驗結果顯示，先酸洗後鹼洗及先鹼洗後酸洗之耐水洗牢度與二次鹼洗之耐水洗牢度結果相近，經過與未還原洗之試樣用分光儀測色，三者相互之間並未有明顯色差，並未因為還原洗方式不同使其織物顏色變化不同。以此結果，若需得到良好之耐水洗牢度，可使用一酸洗一鹼洗的方式，相較使用二次鹼性還原洗，可節省製程時間、使用水量，即可達到相似之耐水洗牢度結果。 T/OP blended fabric have floating colors after dyeing, which will affect the color fastness of the fabric. The quality control of its washing fastness needs to be level 3-4. In order to make the fabric color and color fastness meet the standard. Will be used different reduction clearing of change reagents and times to achieve the required color fastness. In this study, selected the three colors fabric of black, red and royal blue with unstable washing fastness. Frist, used to once reduction clearing with the five acidic and alkaline reduction clearing formulas, and compared the fastness of the five formulas. Next, decided the two of five formulas which have better washing fastness. Finally, used the two formulas with different sequences for continuous reduction clearing. The experimental results show that. The washing fastness of the acid first and then alkaline reduction clearing and the alkaline first and then acid reduction clearing was similar then the second times alkaline reduction clearing. After colorimetric spectrometer, there was no obvious color difference between them. Let means there was no color change to the different working methods. Based on this result, if required good washing fastness, can use to one acid and one alkaline continuous reduction clearing. The methods compare with the second times alkaline reduction clearing, can save the process time and water consumption to be achieve similar washing fastness.
