超临界二氧化碳流体辅助下的纺织品整理技术研究进展

为使超临界二氧化碳（SCCO2 ）流体更好地应用于纺织品功能性整理，以近些年国内外的相关研究为基础，从基本原理、影响因素、整理后纺织品性能变化及具体应用等方面，对SCCO2流体辅助下的纺织品功能性整理进行综述分析。结果表明：整理剂在SCCO2流体中的溶解性能以及被整理纤维的聚集态结构是影响SCCO2流体辅助整理纺织品的关键因素，其次夹带剂的使用和整理过程中温度、压力的变化也有较大的影响；整理后，纤维聚集态结构将发生系列变化，并导致性能变化，而整理剂在纤维或纺织品中的分布情况及含量，将极大影响整理效果。SCCO2流体辅助下的纺织品整理技术应用除目前研究较多的合成纤维整理外，可进一步加强对天然纤维整理及特种功能整理的研究。

Research progress on textile finishing with assistance of supercritical carbon dioxide

In order to apply supercritical carbon dioxide ( CO2 ) on textile finishing, the comprehensive analysis on supercritical CO2 from basic principles, influencing factors, properties change after finishing, and applications in textile finishing at home and abroad were carried out. The results show that the important factors influencing textile finishing with supercritical CO2 are the solubility of finishing agent and the state of aggregation of fiber. In addition, the entrainer, the change of temperature and pressure also greatly influence finishing with supercritical CO2 . The state of aggregation of fiber would generate a series of changes after finishing, and then lead to properties change. The distribution and content of finishing agent in fiber or textile will greatly influence the finishing effect. Besides the application of supercritical CO2 on the finishing of synthetic fibers, the research of natural fiber finishing and special functional finishing with supercritical CO2 should be strengthened.
