超临界二氧化碳染色的原理及研究进展

The Theory and Research Advances of Supercritical CO2 Dyeing

超临界二氧化碳染色技术是一种新型的染整技术,它具有染色时间短、匀染透染性好、染后不用还原清洗等优点,且整个染色过程中不会造成任何污染。解决了传统染色工艺使用大量的水,存在环境污染严重及资源消耗、浪费大,以及有机溶剂染色的生态、成本、很难工业化应用的问题。文章介绍了超临界二氧化碳染色法的基本原理,对国内外超临界二氧化碳染色技术在合成纤维和天然纤维纺织品中的研究现状作了全面分析,并对其发展前景进行了展望。

Supercritical carbon dioxide dyeing was a novel technology for dyeing and finishing.It has the advantages of shorter dyeing time,good levelness and thorough dyeing,without reduction and washing,and it would not cause any contamination in whole dyeing process.The problems of traditional dyeing process such as large resource consumption,severe environmental pollution and the problems of organic solvent dyeing process such as ecological damage,high cost,difficult industrial application were resolved.The theory of supercritical carbon dioxide dyeing was introduced.The research advances of supercritical carbon dioxide technology in synthetic and natural fibers textiles at home and abroad were analyzed comprehensively.The development of it was prospected also.
