摘要
本文研究了棉纤维的稀土预处理对活性染料在棉纤维上上色率的影响,并讨论了稀土浓度、处理温度、处理时间等因素的影响。结果表明:稀土预处理可明显提高活性染料在棉纤维上的上色率;上色率在稀土离子浓度为1.0×10(-6)mol·L(-1)左右时有一极大值,随处理温度的升高而升高,在80分钟内随处理时间而升高,80分钟后基本达到平衡。
An application of rare earths in the treatment of cotton textile fiber was studied,and the effects of rare earths concentration, of the treatment temperature and time on uptake of active dyes on fiber are discussed. The uptake increases with the treating temperature, and reaches a maximum under the condition of rare earths ion concentration of 1. 0×10 ̄(-6) mol/L and treatment time of 80min.
