[交流] 【求助】翻译一段摘要文字谢谢

【为了避免合成染料对环境的污染及对人体的危害，人们重新重视无毒、可再生、色调别致、对人体无刺激、具有天然保健功能且与生态环境具有良好相容性的天然染料。伴随着近几年来染发的时尚流行，研究天然染料的制备以及对头发的染色工艺具有重要的意义。
本文选取在羊毛染色领域中研究较多、染色效果较好的红色系天然植物染料苏木、儿茶为研究对象，研究这两种植物染料的提取及其对头发的染色性能。首先根据两种染料植物的性能，选取不同的溶剂及提取方法，用紫外-可见光分光光度仪测出的吸光度值为依据选取最佳提取工艺。并设计三水平四因素正交试验，探讨染色温度、时间、pH值、媒染剂用量等染色工艺参数对漂白后头发染色效果的影响规律，以电脑测配色系统测量出的提取液上染漂白后头发的颜色特征值为依据，优化了染色工艺。
研究天然染料苏木上染头发颜色的稳定性及漂白后的头发与苏木素之间相互作用的热力学，探索其染色机理。结果表明，染发过程中，苏木被头发吸附的同时，苏木素的脱附作用也在进行，并且也与吸附过程相互竞争。并且漂白后头发对苏木素的吸附过程是吸热的，吸附过程是自发进行的。
用量子化学Gaussian03软件包对头发与天然染料苏木素的相互作用进行理论研究。结果表明，如果苏木染液偏酸性，则苏木主要与头发分子片段中的氨基发生作用；如果染液偏碱性，则主要与头发分子片段中的羧基发生作用。相对来说，在碱性条件下染色时，会使得染色更牢固。其中，尤以在碱性环境中头发与苏木相互作用时，结构更稳定，头发会以氨基季铵盐的形式与苏木相互作用。】

【Synthetic dyes in order to avoid environmental pollution and harm to human body, renewed emphasis on non-toxic, renewable, unique colors, the human body without stimulation, with the natural environment and ecological health functions and good compatibility with natural dyes. With the hair of fashion in recent years, the preparation of natural dyes and hair dyeing process of great significance. This paper selects the field of research in the more wool dyeing, staining the red line better natural plant dye hematoxylin, catechu as the research object, both the extraction of plant dyes and dyeing properties of hair. First, the performance of plants under the two dyes, select a different solvent and extraction method, with UV - visible spectrophotometer measured absorbance value of optimal extraction process based on selection. Four factors and three levels designed experiment, of dyeing temperature, time, pH, amount of mordant dyeing process parameters such as bleached hair dyeing effect law, computer color measurement system to measure the dye bleaching extraction the basis of hair color features to optimize the dyeing process. Research on natural dyes dye your hair the color of hematoxylin stability and bleached hair and the thermodynamic interaction between hematoxylin and explore its dyeing mechanism. The results showed that the dye process, HE was the hair, while the adsorption, the desorption hematoxylin are carried out and also compete with the adsorption process. And after bleaching the hair on hematoxylin adsorption process is endothermic, the adsorption process is spontaneous. Gaussian03 quantum chemistry package used hair dyes hematoxylin and natural interactions are studied theoretically. The results show that, if the acidic dye hematoxylin, the hematoxylin major molecular fragments and hair play a role in amino; if the alkaline dye solution, the main molecular fragment and hair play a role in the carboxyl. In contrast, dyed under alkaline conditions, it will make the stain more solid. Among them, particularly the hair in an alkaline environment interaction with hematoxylin, the structure is more stable, the hair will be in the form of quaternary ammonium salts and amino hematoxylin interactions. 】
