An accurate and rapid method for the evaluation of soil removal has been developed. It may be used to analyze the thermodynamics which oily soil substances are removed from a fiber substrate into an aqueous detergent solution.A liquid chromatography method with fiber power, textile yarn, or woven fabric as stationary phase has been devised for studying the mechanism by which oily soils are removed from a fiber substrate with surfactant. We measured the retention volume of oily soil substrate on polyester or cellulose substrate stationary phase as a function of the aqueous surfactant micelle concentration in the mobile phase.The oily substrate elution volumes and capacity factors were affected by micelle concentrations in the mobile phase. The partition coefficients of the oily substances between the fiber substrate and micelles (PィイD2smィエD2, between the fiber substrate and water (PィイD2swィエD2), and between micelles and water (PィイD2mwィエD2) were determined with the chromatographic treatment involving micellar mobile phases. The PィイD2smィエD2 and PィイD2swィエD2 values for the oily substances were larger for the polyester system than for the cellulose system. The changes in free energy (-Δμ) of oily substances between the micelles and fiber substrate equaled 2.9 〜 3.3 kcal / mol for polyester, and 4.3 〜 4.5 kcal / mol for cellulose, respectively, suggesting that oily substances are much more difficult to remove from polyester than from cellulose.These results are similar to those observed by other investigators using other methods. This chromatography technique may be useful for investigating the dynamic equilibrium between removal and redeposition of oily substances a fabric substrate in detergent solution.

提出了一种快速、准确地评价土壤去除效果的方法。采用液相色谱法，以纤维粉末、纱线或织物为固定相，研究了表面活性剂去除纤维基材上油污的机理。测定了油性土壤基质在聚酯或纤维素基质固定相上的保留体积与移动的相中表面活性剂胶束浓度的关系，油性基质的洗脱体积和容量因子受移动的相中胶束浓度的影响。采用胶束移动的相色谱法，测定了油状物质在纤维基质与胶束之间的分配系数（P_（max）D_2）、纤维基质与水之间的分配系数（P_（max）D_2）、胶束与水之间的分配系数（P_（max）D_2）。对于聚酯体系，油性物质的P β D2 sm β D2和P β D2 sw β D2值大于纤维素体系。聚酯和纤维素在胶束与纤维基质之间的自由能变化（-Δμ）分别为2.9 ~ 3.3 kcal / mol和4.3 ~ 4.5 kcal / mol，表明聚酯中的油性物质比纤维素中的油性物质更难去除，这些结果与其他研究者用其他方法观察到的结果相似。这种色谱技术可用于研究洗涤剂溶液中织物上油性物质的去除和再沉积之间的动态平衡。
