摘　　要：采用超临界二氧化碳流体萃取的方法研究了超临界二氧化碳流体处理对苎麻织物的成分和性能的影响。通过测定苎麻织物胶质成分含量、上染性能、白度、强度、透气性能、毛细效应和透湿性能指标等,研究经超临界二氧化碳处理后苎麻织物的性能。结果表明:超临界二氧化碳处理可以降低苎麻织物中的胶质含量,提高苎麻织物的透气透湿性、毛细效应、染色性能等,从而提高苎麻织物的服用舒适性能;超临界二氧化碳处理使织物的强度及白度下降,但下降幅度较少,对织物影响不大。This paper investigated the influence of supercritical CO2 fluid treatment on the structure and properties of ramie fabrics by extraction method.Composition and content of the gum,dyeing property,whiteness,strength,capillary effect and permeability of the ramie fabric treated by supercritical CO2 fluid were measured,and it was found that the pectin content of the ramie fabric decreased,the permeability,capillary effect,dyeing property improved,thus enhancing the wearability of the fabric.Though the strength and whiteness decreased slightly,it had little effect on the fabric.
