Research on Degumming and Bleaching Apocynum venetum in one-Bath Alkali-H2O2
This paper researched the process rapidly degumming and bleaching apocynum venetum, which is one-bath alkali-H2O2 method and a specific technique. The three-factor quadratic general rotary unitized optimization design was used to analyze the three parameters mostly affecting the degumming and bleaching process: the NaOH concentration, the H2O2 dosages and the processing time. Through the experiment, calculation, analysis and verification, the optimum combination of the three parameters for degumming and bleaching process was gotten: NaOH concentration 10～11(g/L), H2O2 dosages 9.5～10.5(g/L), processing time 120～135(min).
