摘要
以一个染色模型模拟分散染料的氨纶染色,在此基础上得到分散染料与氨纶纤维大分子的结合发生在硬链段区表面上的结论。并从上染速率曲线、吸附等温线这两方面对分散染料氨纶染色的染色机理作了初步的探讨。
Some dyeing mechanisms of fiber - forming polyurethane with disperse dyes are studied. The dyeing rate curve and adsorption isotherms are obtained. With a model experiment designed, a representation of the localization of the dyestuff molecules in the fiber structure can be pictured.
