我國紡織染整業之環境中，隨處可見使用化工染料進行染色，由於化工染料染色後之成效，能給予服飾繽紛色彩與便利的同時，但相對易影響環境污染與廢水處理之問題產生。現今在全球綠色環保與環保意識的抬頭之下，如何提升清晰淨化的環境以及注重消費者身體健康等等因素。因而天然中藥色素應用於纖維染色性之研究又再度引起關注。本研究以天然中藥色素應用中，依色素化學屬類分為九大類染料，進而萃取出其天然色素，再針對蠶絲纖維經不同媒染劑處理後，分別檢測著色程度，耐洗色堅牢度及耐摩擦色堅牢度之變化情形。研究結果得知，1.依色素化學屬類分為九大類染料中，中藥染材萃取染料染著蠶絲纖維經不同媒染劑處理後的色相變化，皆能染出各種色相。2.耐洗色堅牢度方面以硫酸亞鐵作為媒染劑時，耐洗色堅牢度皆維在3-4級以上；以硫酸鋁處理時，其耐洗色堅牢度皆維在3-4級以上；若以硫酸銅作為媒染劑時，耐洗色堅牢度皆維在3-4級以上。3.耐摩擦色堅牢度方面 以硫酸亞鐵作為媒染劑時，耐摩擦色堅牢度皆維在3-4級以上；以硫酸鋁處理時，唯五倍子的耐摩擦色堅牢度為4級；若以硫酸銅作為媒染劑時，耐摩擦色堅牢度皆維在3-4級以上。
Regarding domestic textile dyeing and finishing industry, inorganic pigments are commonly used in dyeing silk fabric due to its powerful coloring effect. However, at the same time of giving clothe its colorful and brilliant hues, inorganic pigments also cause problems like environmental pollution and wastewater production. In today’s world where public awareness towards environmental protection is on the rise, issues like environmental protection and customer health should also be fully concentrated on. Therefore, Chinese medicine pigment’s function in dyeing silk fabric has once again received public attention, which is indeed an issue worth our further investigation. According to chemical properties, pigments can be subdivided into 9 major categories. After processing silk fabrics with different mordant (or dye fixatives), natural pigments are extracted from Chinese medicine and applied to the processed silk fabric to test their color fastness, washing color fastness, and rubbing color fastness. Here are the study results: 1. According to pigments’ chemical properties, pigments are subdivided into 9 major categories. After processing silk fabrics with different mordant (or dye fixatives), natural pigments are extracted from Chinese medicine and applied to the processed silk fabric. It turns out that all kinds of hue can be successfully created. 2. In terms of washing color fastness: washing color fastness can be maintained at a level above 3~4 when iron (II) sulfate is taken as mordant (or dye fixatives); washing color fastness can be maintained at a level above 3~4 when aluminum sulfate is taken as mordant (or dye fixatives); washing color fastness can be maintained at a level above 3~4 when copper sulfate is taken as mordant (or dye fixatives). 3. In terms of rubbing color fastness: rubbing color fastness can be maintained at a level above 3~4 when iron (II) sulfate is taken as mordant (or dye fixatives); rubbing color fastness can be maintained at a level above 4 when aluminum sulfate is taken as mordant (or dye fixatives); rubbing color fastness can be maintained at a level above 4 when copper sulfate is taken as mordant (or dye fixatives).
