Based on a survey of the mechanism for reactive dyes containing β-hy-droxy-ethyl sulfonyl sulfuric ester on the cellulosic fibre, and the structures of non-ionic nature of disperse dyes , a new range of reactive disperse dyes for polyester cotton blends is proposed.

本文综合分析了含β-羟乙基碸硫酸酯基活性染料的染棉机理和聚酯纤维用非离子型分散染料的结构特点，提出了一类用于涤棉混纺织物的含β-羟乙基碸硫酸酯基活性分散染料。

The effect of flow rates, initial concentrations, resin bed heights, its height/ diameter ratios and temperature on breakthrough curves of sulfuric acid/2-naphthalenesulphonic acid, 2-naphthalenesulphonic acid/sulfurous acid and sulfuric acid/ 2-naphthalenesulphonic acid/sulfurous acid systems was investigated. Excellent agreement was obtained between experimental data and the suggested breakthrough data model, with which the breakthrough curves can be accurately predicted for multi-component adsorptive separation in resin bed, the experiment of adsorptive separation may be scaled up, and the plant may be designed.

考察了流速，初始浓度，床层高度，床层高径比，温度等因素对硫酸-2-萘磺酸，2-萘磺酸-亚硫酸和硫酸-2-萘磺酸-亚硫酸等混合体系穿透曲线的影响，所建立的穿透曲线模型与实验结果拟合较好，模型可较准确预测多组分吸附分离的穿透曲线，可用于指导吸附分离实验的放大以及装置的设计。
