摘要
In improving the application convenience of the first generation of starch based fixing agents (SBFs) which are made by cationization followed by acid hydrolysis, three new SBFs were made respectively by degrading the molecular weight of raw starch with acid hydrolysis, enzymatic hydrolysis and hypochlorite oxidation, followed by etherification. The degree of substitution and molecular weight of the three SBFs were controlled to be similar. The performance of these experimental SBFs in controlling the dissolved and colloidal substances and paper strengthening was measured and compared to that of a traditional polyamine fixative. The results show that the polyamine fixative is better in neutralizing the dissolved substances, while the SBFs are better in fixing the colloidal substances and better in enhancing paper strengths. Among the SBFs, the effectiveness of controlling dissolved and colloidal substances and paper strengthening, from best to worst, is in the order of enzymatic, acid and finally hypochlorite degradation.
