【摘要】 运用MatLab处理染料浓度、吸光度、上染率的相互关系,可获得有关染料的上染速率曲线。由于染料稀溶液的浓度与吸光度的关系符合朗伯比尔定律,故能以一组准确的染料浓度与吸光度的对应关系,建立标准曲线及其方程。以分光光度计测定恒温染色不同时刻的染液吸光度,再由MatLab拟合出的标准曲线方程式计算出相应时刻的染液中染料浓度,对照初始浓度推断该染料不同时刻对纤维的上染率。以MatLab对恒温条件下的上染率与上染时间拟合,获得该染料恒温条件下的上染速率曲线方程式和图形。更多还原

【Abstract】 The data about the concentration of dye liquor,absorbency and dye uptake,can be used for dyeing rate′s curve fitting on MatLab.Since the relation between the concentration of dye liquor and absorbency follows Lambert-Beer law, standard curve and equation can be established based on the correlation of a set of known concentrations of dye liquor and absorbency.Testing the absorbency of the dye liquor at a group of time-series,the corresponding dye uptake can be determined according to the standard curve.Combining the dye uptake with the time,the dyeing rate curve can be founded with a range of absorbency data in different time corresponding with standard curve.The dyeing rate curve is preserved finally both in multinomial and figure on MatLab.The detail of the data processing about the dyeing rate on MatLab,is showed in the paper.更多还原
