細丹尼聚丙烯纖維的優良物性,使其具有很高的附加價值。但是聚丙烯結晶度高、缺乏染色基座,不易染色,而原液染色使用的顏料不適用於細丹尼聚丙烯纖維的著色。因此在本文中嘗試使用屬於偶氮型分散性染料的C.I. Disperse Orange 1、C.I. Disperse Orange76、C.I. Dis- perse Yellow 3、蒽醌型分散性染料之C.I. Disperse Red 60、C.I. Disperse Blue 3和雜環型分散性染料C.I. Disperse Yellow 54等六種結構各異的分散性染料,嘗試應用新式的超臨界流體染色技術以及不同比例的水/甲苯混合之溶劑染色方式,以解決細丹尼聚丙烯纖維不易染色之問題。
實驗結果顯示:以水和甲苯混和作為溶媒,其染著量僅達1.9μmole/g,無法有效的讓細丹尼聚丙烯纖維上色,而超臨界二氧化碳流體對聚丙烯的塑化能力較大,能藉由選擇適當的染色條件獲得較佳的染色效果,可達到8.11μmole/g,惟染色堅牢度均不甚理想,尤其是水洗堅牢度最高僅達3級。在超臨界二氧化碳系統中染色處理溫度高於100℃時,由於再結晶作用而明顯改變其結晶性質。由微差掃描熱分析和X射線繞射分析結果發現,染料本身的吸熱特性對染色後細丹尼聚丙烯纖維之熱性質並無很大的影響。

Some unique properties of fine denier polypropylene fibers take advantage in commercial uses. The high degree of crystalline and absence of dyeing site, however, result in its poor dyeability of polypropylene. Pigments using in dope dyeing does not appropriate for spinning of fine denier polypropylene fibers. For this reason, an attempt to overcome this problem by using two dyeing processes of supercritical carbon dioxide fluids and water/toluene as dyeing medium, with three disperse dyes of azo structure (C.I. Disperse Orange 1,C.I. Disperse Orange 76 and C.I. Disperse Yellow 3), two of anthraquinone structure (C.I. Disperse Red 60 and C.I. Disperse Blue 3) and one of heterocyclic structure (C.I. Disperse Yellow 54) were used in this study.
The results reveal that medium of water/toluene does not capable of dyeing fine denier polypropylene fibers which showed 1.9μmole/g dye amount on fiber. On the contrary, supercritical carbon dioxide fluids carries out better dyeing effort due to its greater plasticizing ability for polypropylene which showed more than 8.11μmole/g dye amount on fiber, but still the unaccep-tably low washing fastness(up to degree 3)can not besettled. Through the analysis of Differential Scanning Calorimetry (D.S.C.) and X-Ray Diffraction(X.R.D.), we find it will cause remarked change in crystalline structure of fine denier poly-propylene fibers as temperature higher than 100℃.And the heat absorption behavior of dyestuff do not have much influence to the thermal properties of dyeing specimen.
