本研究針對改質聚丙烯纖維，主要研究使用市售之三原色分散性染料，以相同溫度、時間及壓力在超臨界二氧化碳中，對改質聚丙烯纖維進行染色、，並對改質聚丙烯纖維染色織物，進行表觀色濃度及各項染色堅牢度進行評估、從染色結果得知、，染料進行萃取後，於超臨界二氧化碳染色的相對上色率會比沒有進行萃取的染料還要高、經去分散劑的三原色染料其檢測的評級級數，大部分低於未去分散劑的三原色染料、，且經還原洗階段的布樣其水洗牢度、乾溼磨擦牢度、耐水牢度耐汗液牢度(酸)以及耐汗液牢度(鹼)均達商用標準3-4級以上

This study focused on modified polypropylene fiber as the main research object, using commercially available trichromatic disperse dyes, dyeing modified polypropylene fibers in supercritical carbon dioxide at the same temperature, time and pressure, and then the modifying polypropylene dyed fabrics were evaluated for their apparent color strength and various dyeing fastness. From the results of the dyeing, the relative dye uptake of dyes used for supercritical carbon dioxide dyeing after extracted of dyes is higher than the un-extracted of dyes. The assessing of the fastness of the trichromatic dyes that have undergone the dispersant is mostly less than the trichromatic de-dispersant dyes. After the reduction washing stage, the washing fastness, dry and wet rubbing fastness, water fastness, fastness to perspiration (acid), and fastness to perspiration (alkali) were all above commercial grade 3-4.
