摘要
为了给染料上染纤维配以较为准确的数学模型,以希尔公式为基础,结合实验数据分析,采用多项式曲线拟合,建立上染率动力学模型。以活性RR-红、弱酸性绿GS和分散红玉S-2GFL分别上染针织物为例,利用建立的上染率动力学模型以及希尔公式计算这3组染料不同时刻对应的上染率,并与实际测得的上染率进行比较。结果表明,新建的上染率动力学模型其计算结果略优于希尔公式,特别是当染料上染接近平衡状态时预测的上染率与实际的测量值更为吻合。
For accurate computation of the dye uptake rate of the fiber, this paper has developed a kinetics model for simulating the dye uptake rate by using multiple curve-fitting in combination with experimental data analysis on the basis of Hill equation. Knitted fabrics are dyed with Reactive Red RR, Weak Acid Green GS and Disperse Crimson S-2GFL respectively and the dye uptake rates at different times of these three groups of dyes are computed using this kinetics model and Hill equation and the results obtained are compared with the practical values measured. It showed that this new model is slightly advantageous over Hill equation, and in particular, the predicted dye uptake rate by the model is more agreeable with the actual value when up-taking of dye nearing the state of balance.
