稀土改性尼龙66染色机理的研究

Dyeing Mechanism on Rare Earth Metal Modified Nylon 66 Fabrics

近几年来,稀土化合物在纤维染色过程中的应用取得了良好效果.随着稀土染色的推广和应用,对稀土染色机理的研究也愈加引起人们的关注.有人在研究锦纶和涤纶稀土染色时提出了分子络合理论,认为在染色过程中,稀土化合物的加入会生成纤维大分子-稀土离子-染料分子复杂的配位体,从而改善了染色效果.

An increase of dye uptake and improvement of dyeing properties of acid dye have been achieved on rare earth metal modified nylon 66 fabrics. The interaction between fiber, dye and rare earth ions and the type of how the interaction takes place were studied by examining the IR and visible spectra and the change of the dye solubilities. A dyeing mechanism of acid dyes in water on such fabrics was then proposed.
