活性染料上染率的多元预测模型分析

 为预测染色过程中的上染率,有效提高染色产品的质量和染料的利用率,在分析上染率试验数据的基础上,确定影响染料上染率的最主要因素为染料用量、染色时间及温度,并建立上染率与3个主要影响因素的一元特性模型。在此模型的基础上,构建上染率的多元非线性预测模型,最终实现对染料上染率较精确的预测。试验结果表明,利用该多元模型计算得到的上染率预测值与实际值基本相符,证明该方法切实可行。

Analysis of reactive dye uptake-rate model of multivariate regression

For the purpose of prediction of dye uptake rate and improving the quality of dyed products and utilization of dyestuff,this paper,based on analyzing actual experimental data of dye uptake rate,determined the key factors influencing uptake rate as follows: the concentration of dyestuff,dyeing time and temperature.Then,a single characteristics model of relation between the three key factors and uptake rate was established.Finally,a prediction model of multivariate nonlinear regression was developed and more accurate prediction of dye uptake rate was realized with it.The results predicted by the model of multivariate nonlinear regression show in good agreement with actual values,and the feasibility and validity of this method have been verified by practical experimental observations.
