Abstract

In this study, five blue disperse dyes were dyed at different concentrations (1%, 2%, 4%, 8% o.m.f.) at a high temperature and high pressure dyeing method and dyeing with supercritical carbon dioxide at 1% o.m.f. . The apparent color strength (K/S value) was used to find dyes with the high relative rate of dye uptake and suitable dyes for supercritical carbon dioxide dyeing. The result showed that dye uptake of Dye BLUE A and Dye BLUE B are lower, so these dyes are not suitable for supercritical carbon dioxide staining. The apparent color strength values of Dye BLUE C and Dye BLUE D tend to be close to that of conventional high temperature and high pressure dyeing (4% o.m.f.), but due to the relative rate of dye uptake at first time in first time supercritical carbon dioxide dyeing, so these dyes may not be suitable for supercritical carbon dioxide dyeing. Only the apparent color strength value of Dye BLUE E is high enough and the primary relative rate of dye uptake is 90.477%. It should be suitable for supercritical carbon dioxide dyeing. Finally, the results of dyeing fastness showed that the dyeing fabrics with various fastness up to grade 4 were in needs with commercial.?

摘要

本研究係使用5支藍色分散性染料在不同濃度(1%, 2%, 4%, 8% o.m.f.)以傳統高溫高壓染色與濃度 1% o.m.f.以超臨界二氧化碳進行染色後，檢測其表觀色濃度(K/S值)，藉此找出相對上色率高且適合用於超臨界二氧化碳染色之染料。實驗結果發現染料BLUE A與染料BLUE B表觀濃度值相對較低不適合用於超臨界二氧化碳染色，而染料BLUE C及染料BLUE D雖然表觀濃度值趨近傳統高溫高壓染色(4% o.m.f.)，由於一次上色率不佳，可能也不適合用於超臨界二氧化碳染色，只有染料BLUE E表觀濃度值夠高，一次上色率也達90.477%，應較適合用於超臨界二氧化碳染色。最後經染色堅牢度結果得知各染色布樣的各項染色堅牢度都達到4級均符合商業需求。
