The application of peracetic acid and sodium percarbonate in green production processing of ramie

摘要

The drawbacks of traditional chemical degumming for raw ramie are long process line, huge energy consumption, with large environment pollution, and low efficiency. Therefore, an attempt has been made to carry out degumming of ramie with an ecofriendly chemical namely, peracetic acid and sodium percarbonate in this communication. Compared with the traditional chemical degumming process, the oxidation degumming process with the characteristics of environment-friendly production technology is short process, less pollution, low energy consumption and high production efficiency and so on. Meanwhile, the hydrolysis products of peracetic acid and sodium percarbonate do a little harm to the environment. Tenacity, fineness, and breaking elongation of degummed samples were determined by standard methods. The results were confirmed through COD, pH, colority, SEM, tensile properties etc. The performance of peracetic acid degumming and sodium percarbonate degumming were also compared with conventional chemical degummed fiber. In addition, the COD, pH value, colority of degumming solution is greatly reduced using oxidation degumming process, environmental pollution and sewage treatment costs are significantly reduced.
