文中测定了阳离子染料上染腈纶基牛奶蛋白复合纤维的上染速率曲线，且分析了不同温度对半染时间、扩散系数、染色速率常数等染色动力学参数的影响。结果表明，阳离子染料上染腈纶基牛奶蛋白复合纤维的初染率很高，染色120 min时达到上染平衡；阳离子染料上染腈纶基牛奶蛋白复合纤维的半染时间较短且随着温度的升高有下降的趋势，其扩散系数和染色速率常数都随着染色温度的升高而逐渐增大。
文中測定瞭暘離子染料上染腈綸基牛奶蛋白複閤纖維的上染速率麯線，且分析瞭不同溫度對半染時間、擴散繫數、染色速率常數等染色動力學參數的影響。結果錶明，暘離子染料上染腈綸基牛奶蛋白複閤纖維的初染率很高，染色120 min時達到上染平衡；暘離子染料上染腈綸基牛奶蛋白複閤纖維的半染時間較短且隨著溫度的升高有下降的趨勢，其擴散繫數和染色速率常數都隨著染色溫度的升高而逐漸增大。

The dyeing rate curve of acrylonitrile base milk fiber with cationic dyes was tested. The effects of different temperatures on dyeing kinetic parameters such as half-dyeing time, diffusion coefficient and dyeing rate constant were analyzed. The results show that the initial dyeing rate of the acrylonitrile base milk fiber dyed dy cationic dyes is very high. And it reaches dyeing equilibrium after 120 min dyeing time; The half-dyeing time of acrylonitrile base milk fiber dyed by cationic dyes is short and can be decreased with the increase of temperature. Besides, diffusion coefficient and dyeing rate constant can be gradually increasing with the increase of the dyeing temperature.
