替代:纺织化学品的可持续发展之路|走可持续发展之路

　　从19世纪开始合成染料替代沿用几千年的天然染料；从后期种类繁多的活性染料、酸性染料、分散染料等取代早期单一的直接染料；同时，随着人们对服用纺织品功能性需求的增加，各类功能型纺织化学助剂被逐步研制、创新、并应用到纺织品中。回首这段历程，我们可以清晰地看到，纺织化学品的使用就是一次又一次的替代、取代、创新、升级的过程。在不同时期选择合适的、最符合当时人们需要的商品去满足社会需求，是每个生活在当时社会条件下的人们所绞尽脑汁去思考的问题。也许，当时的选择仅能满足当时的需求；也许，些须时日后，这样的选择就被未来的社会所遗弃。但是，社会在进步，需求在改变，真理不必永恒，创新方能前进！
　　如今，传统的纺织化学品已不能满足人们对健康、生态、安全等方面的需求。如何寻找到合适的、能满足当前人们需求的、并能替代传统的、不合时宜的纺织化学品，已成为纺织化学研究人员所面临的最大工作。本期特稿推出相关文章，以求能为广大纺织化学工作者提供些须思路。
　　In the 19th century, natural dyes used for thousands years were replaced by synthetic dyes. In the 20th century, direct dyes which had been used in early time were replaced by reactive dyes, acid dyes, disperse dyes and so on. With the increased demand for function of garment, more and more functional textile auxiliary have been created and used in fabrics. Looking back at this history, we can see that the development of textile chemicals is constantly replaced and innovated. Maybe some choices which only meet the demand of that time and will be abandoned in the future, just so, these replacements and innovations promoted our society progress continuously.
　　Today, traditional textile chemicals are difficult to meet our needs in health, ecology and safety. It is necessary for us to seek the new textile chemicals. Some new ideas have been mentioned in this Special Feature, please follow it, perhaps it will give you some help.
