摘要
本文通过向染色系统中加入不同性质的有机溶剂,提高了上染率,并分析得出提高上染率的关键原因是溶剂对染料一定的溶解度和膜内外的浓度梯度为染料单分子跨膜提供了推动力。
In disperse dye micro-porous membrane dyeing,the dye uptake was improved by adding different organic solvents. The key of the improving was solubility of the dyes and the concentration gradient between inside and outside of the micro-porous membrane.
