稀土在活性染料真丝绸染色中的应用及染色机理

Application and Mechanism of Rare Earth in Real Silk Dyeing with Reactive Dyestuff

本文研究稀土离子与真丝纤维的作用性能,讨论稀土盐类能显著提高活性染料在真丝上固色率的机理。结果表明,稀土离子不会提高染料与丝纤维固色速率常数,主要是改变纤维的电性效应结果。

Discusses the function of rare earth ions toward real silk fibre and the mechanism in real silk dyeing with reactive dyestuff in the presence of rare earth salt. The results show that rare earth improves notably the dye fixation mainly because of its function of changing the electric effects in the fibre.
