| 摘 要： | 采用直接湖蓝5B研究树状大分子PAMAM改性海藻酸钙纤维的染色动力学,包括上染速率曲线、半染时间、平衡上染百分率、比染色速率常数和扩散系数。与未改性的海藻酸钙纤维相比,PAMAM改性海藻酸钙纤维的染色性能大大改善,且改善程度与纤维中PAMAM的含量成正比。随着改性海藻酸钙纤维中PAMAM含量的增加和染色温度的升高,染料的平衡上染百分率提高,半染时间缩短,比染色速率常数增大,扩散系数增加,海藻酸钙纤维的染色性能得到改善。

| Abstract: | Dyeing kinetics of alginate calcium fibers modified with PAMAM was studied using direct lake blue 5B,including dyeing rate curve,half dyeing time,equilibrium dyeing percentage,dyeing rate constant and diffusion coefficient.Compared with original alginate calcium fibers,the dyeing behavior of alginate calcium fibers modified with PAMAM was improved greatly. With the increase of the dendrimer's content and temperature,equilibrium dyeing percentage was raised,half dyeing time was decreased,dyeing rate constant... |
