An analysis is provided of the various models that have been proposed to account for the manner by which added NaCl or Na2SO4 promotes the uptake of reactive on cellulosic fibres. Although conventionally, mathematical interpretations of isothermal equilibrium dye adsorption data are employed to describe the mechanism by which reactive dye adsorption occurs, such an approach does not satisfactorily explain why reactive dyes display inherently low uptake on cellulosic fibres in the absence of added inorganic electrolyte, nor does it explain why added inorganic electrolyte is so effective in promoting dye uptake.

助剂在纺织品纤维浸染中的作用:传统模型的第6部分分析,描述了无机电解质促进纤维素纤维上活性染料吸收的方式
提供了对已提出的各种模型的分析,以解释添加的NaCl或Na 2 SO 4促进纤维素纤维上反应性吸收的方式。尽管通常采用等温平衡染料吸附数据的数学解释来描述反应性染料发生吸附的机理,但这种方法不能令人满意地解释为什么在不添加无机电解质的情况下反应性染料固有地在纤维素纤维上的吸收率较低,或者是否解释了为什么添加无机电解质如此有效地促进染料吸收。
