畢 業(yè) 論 文甲基丙烯酸甲酯存在下滌綸分散染料低溫染色甲基丙烯酸甲酯存在下滌綸分散染料低溫染色摘 要滌綸纖維性能優(yōu)良,但是纖維結晶度高,缺少極性基團,染色困難。盡管分散染料高溫高壓染色是一種比較好的染色方法,但是近年來,人們追求服裝個性化、多樣化和功能化,多元纖維復合織物應用更為廣泛,一些不耐高溫的纖維,如羊毛、蠶絲、醋纖、氨綸等與滌綸纖維混紡,染色溫度受到限制,研究如何在常壓條件下染色已成為當前發(fā)展的趨勢。本文主要探討了滌綸分散染料染色新工藝,即采用甲基丙烯酸甲酯改進滌綸分散染料染色工藝,并對分散染料常規(guī)染色工藝和甲基丙烯酸甲酯存在下分散染料染色新工藝進行了研究和對比。結果發(fā)現(xiàn),在低溫染色條件下,甲基丙烯酸甲酯對于改善滌綸纖維的染色性能起到了重要的作用,這為滌綸分散染料低溫染色提供了新途徑。關鍵詞 滌綸;分散染料;低溫染色;甲基丙烯酸甲酯THE LOW TEMPERATURE DYEING OF POLYESTER WITH DISPERSE DYES IN THE PRESENCE OF METHYL METHACRYLATEABSTRACTPolyester(PET) fibers possesses many good performances. But its dyeing behaviour is very poor from an aqueous dyebath because of the high degree of crystallinity and the lack of dyeing groups in fibers. Dyeing at high temperature is a better way and more mature technology. But in recent years, individuation, diversification and function of costume are pursued, so the posite fibers are applied widely. The blended PET fabrics with other fibers such as wool, silk, acetate cellulose and spandex and so on are not endured high temperature. Therefore, the dyeing of PET fiber at atmosphere pressure is a developmental current at present.In this paper, polyester fabric was dyed with disperse dye in the presence of methyl methacrylate. The effect of methyl methacrylate on the dyeing properties was studied., especially between the conventional dyeing methods and the new technical dyeing methods when methyl methacrylate appears. The results show that the presence of methyl methacrylate improves the dyeing properties of polyester fabric. The dye uptake and K/S value increase significantly even at a low dyeing temperature.KEY WORDS polyester;disperse dyeing;low temperature dyeing;methyl methacrylate目 錄中文摘要 ……………………………………………………………………Ⅰ英文摘要 ……………………………………………………………………Ⅱ1 前言 ……………………………………………………………………… 1 滌綸纖維的結構和染色性能…………………………………………1 滌綸的染色方法………………………………………………………1 高溫高壓染色法…………………………………………………1 熱熔染色法………………………………………………………2 載體染色法………………………………………………………2 本實驗研究內容…………………………………………………22 實驗部分……………………………………………………………………4 實驗材料及設備………………………………………………………4 實驗材料…………………………………………………………4 實驗藥品…………………………………………………………4 實驗儀器…………………………………………………………4 實驗方法………………………………………………………………4 染色工藝…………………………………………………………4 測試方法…………………………………………………………4 實驗結果與討論………………………………………………………6 染料濃度對上染百分率和 K/S 值的影響………………………6 染色溫度對上染百分率和 K/S 值的影響………………………6 染料時間對上染百分率和 K/S 值的影響………………………7 甲基丙烯酸甲酯濃度對上染百分率和 K/S 值的影
