摘要/Abstract

摘要： 采用95%乙醇从红豆杉叶中提取叶绿素，优化提取工艺，并将其制备成叶绿素锌钠盐，对羊毛织物进行染色，研究了染色温度、色素用量对染色效果的影响。研究结果表明，从红豆杉叶中提取叶绿素的较佳工艺条件：采用95%乙醇，在提取温度60℃和料液比为1:15的条件下浸提2h。羊毛织物在制备的叶绿酸锌钠盐染液中染色，温度90℃时K/S值最大，且叶绿素锌钠盐用于羊毛织物染色具有较好的提升性。染色毛织物的水洗牢度较好，日晒牢度有待提高，在紫外光照射下，织物的最大吸收波长发生变化，K/S值有所降低。

Abstract: Chlorophyll was extracted from Taxus chinensis leaves with 95% ethanol and the extraction process was optimized. Sodium zinc chlorophyllin was prepared from the extraction and was used for wool fabric dyeing. Effects of dyeing temperature and dye concentration were investigated. The results showed that better extraction conditions of chlorophyll in the leaves were 95% ethanol, extraction temperature 60°C, solid to liquid ratio 1:15 and extraction time 2h. Wool dyed with sodium zinc chlorophyllin obtained the maximum K/S value when dyeing temperature was 90°C. Sodium zinc chlorophyllin had good build-up property on wool fiber. Dyed wool fabric showed good washing fastness and light fastness was needed to improve. The maximum absorption wavelength of wool changed and K/S value decreased under the ultraviolet radiation.

Key words: Taxus chinensis leaf, chlorophyll, sodium zinc cholrophyllin, wool, dyeing
