Sodium percarbonate: A new type of degumming reagent applied to the production of ramie degumming
Sodium percarbonate has been widely used in industries. However, it has not found any reports about the application of the sodium percarbonate in degumming of bast fiber. In this paper, the application of the sodium percarbonate in ramie degumming process was investigated and discussed. The research showed that sodium percarbonate can be effectively used in the degumming of ramie. An acid treatment with 2g/L H2SO4 solution at a temperature of 50℃ for 1 hour was found to produce the degummed ramie fibers with the thinnest fineness and the highest tenacity. The experimental results showed that with the sodium percarbonate, the fiber strands in degummed ramie fibers decreased greatly, while tenacity and breaking elongation of the fiber decreased slightly.
