| 摘要: | 本研究係以反應性染料之印花色糊，經印花後分析色糊的存放時間及不同類型反應性染料之水解速率。其中主要針對低、中、高三種反應性染料之色糊於不同置放溫度及時間下探討黏度、酸鹼度(pH值)及上色性之變化，求其染料之印染後之染色堅牢度及水解速率常數。由結果顯示，低反應性染料色糊當置放溫度為30℃時，且置放時間不超過一週時，色糊仍具良好之再利用性，不僅上色率高且染色堅牢度亦佳。另不同反應性之反應染料以低反應型在pH=7時水解率常數最小，亦即水解速率最慢。
The main purpose of this research is to analyze the preservative time of the printed dye colour paste that dealt by reactive dye. The study is looking forward to analyze viscosity and pH of low-active dye colour paste that placed in different temperature and time. Then to test its viscosity, pH, colour fastness and hydrolysis rate with hi-active dye colour paste, and mid-active dye colour paste and low-active dye colour paste in 40℃ ~50℃. The result shows that it's better to preserve the low-active dye colour in the environment below 30℃ but its preserved limit of a week. And the low active dye colour paste has the best performance in viscosity, k/s and colour fastness. When pH=7, the low active dye colour paste has the least hydrolysis rate constant and the lowest reacted rate. |
