天然染料及其染色(待续)

Natural dyes and their dyeing (to be continued)

天然染料的历史可追溯到3000年前,那时人们已开始用天然染料染色,公元前150年,已能把黄、红、蓝三原色天然染料拼混染成各种颜色。19世纪中叶,开创了合成染料新纪元,天然染料逐渐消亡。由于天然染料的绿色环保,30年前重新掀起天然染料新的提取和染色方法的研究。概要介绍一些重要的天然染料及其化学结构以及天然染料古代和现代的染色方法,根据化学结构与染色方法归拼到现代染料分类中去。

The history of natural dyes dates back to 3000 years ago when natural dyes had been applied in dyeing.In 150 BC,three primary colors of natural dyes had been combined for different colors.In the mid-19 th century,synthetic dyes marked a new epoch and natural dyes died gradually.Due to green environmental protection of natural dyes,the research of natural dyes extraction and dyeing was gained attention again thirty years ago.This paper introduces some natural dyes and their chemical structures as well as ancient and modern dyeing methods of natural dyes.According to chemical structure and dyeing method,natural dyes are classified to modern dyes classification.
