Influence of supercritical CO_2 fluid treatment on ramie fabrics

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.
