Abstract:
Technical processes of chemical method, chemical and biological mixing method and biological enzymatic method for flax rove’s scouring and bleaching were summarized. In order to solve the existing problems of long process , high water and energy consumption and severe environmental pollution, scouring and bleaching technique for flax rove in supercritical CO2 fluid was proposed. The characteristics of supercritical CO2 fluid and the application of enzyme in supercritical CO2 fluid were analyzed. Base on the first supercritical CO2 scouring and bleaching apparatus for flax rove in China, scouring and bleaching of flax rove was elaborated in reaction vessel under different temperature fields, pressure fields as well as fluid fields using xylanase and hemicellulase as the compounded biological enzymes in supercritical state. It is pointed out that several exploration work should be conducted, according to characteristics of scouring and bleaching method in supericritical CO2.
Key words: flax, rove, scouring and bleaching, biological enzyme, supercritical carbon dioxide
