A Study on the Kinetics of Reaction between Hydrogen Peroxide and Acidamide Activators during Bleaching

本文作者对酰胺类漂白活化剂与过氧化氢的反应动力学进行了研究。建立了弱酸性条件下过氧化氢活化反应的速度方程,并计算出了活化反应速度常数、半衰期及活化能等动力学参数,从而为过氧化氢在弱酸性条件下的活化漂白工艺提供了理论基础。

The authors study the configuration of combination of anionic dyes with cationic modified ramie fibre by the extraction from DMF together with the technigues of glacial acetic acid and IR spectrometry. The result reveals that various anionic dyes can combine with cationic modified ramie fibre to form ionic bond, the partial reactive groups in reactive dyes also can react upon the hydroxy group in ramie fibre to form covalent bond, but the ratio between covalent bond and ionic bond is going up along with the growth of pH value in dye bath. The research of this paper is of great guiding effect for the dyeing of cationic modified ramie fibre.
