摘要
本文对稀土（ＲＥ）在皮革染色过程中所起的作用进行了初步探讨。通过比较稀土助染与常规染色的上染率，染色过程曲线，染色后成革的外观及理化性能，认为稀土在皮革染色过程中除具有匀染作用外，还能提高染料在革上的上染率，并能改善成革的染色牢度。
The effects of RE in dyeing process were studied initially in this paper. The dyeing ratio, dyeing ptocess-curve, appearance and properties of leather dyed with RE-assisting dyeing were compared with those of leather dyed with normal dyeing. The results have shown that RE is a better assisting-dyeing agent. It can increase dyeing-ratio and improve dyeing fortness. The goods dyed with RE-assisting dying have a bright and full colour appearance.
