Research on the oxidation degumming of ramie with alkaline pectinaseand sodium percarbonate
The application of the alkaline pectinase and sodium percarbonate in the degumming of ramie was studied in this paper.According to the tests such as the fiber fineness,the single fiber tenacity and the fiber surface properties,alkaline pectinase and sodium percarbonate on the properties of degummed ramie fiber was discussed.The results showed that the effect of the degumming of ramie was associated with temperature,concentration of alkaline pectinase,time and pH value.When the temperature is 60℃,the time is 3 hours,the concentration of alkaline pectinaseis 3g/L and pH 8.5,the tenacity of fiber is the highest,the fineness is the finest.Due to the application of sodium percarbonate in the inactivation process,the properties of degummed ramie fiber have been further improved and the gum of the fiber surface has been further reduced.
ramie alkaline pectinase sodium percarbonate oxidation degumming fiber property energy saving and emission reduction
