一种用于评估土壤清除已经开发出来的精确和快速方法。它可能会用来分析热力学，其中的石油土壤物质被从纤维物质中去除，进入一种特殊的分离解决方案。一种带有纤维功率、纹理纱线或编织结构的液体色谱法方法，即静态相位已经被修改用于研究机理的石油土壤被从具有表面活性剂的纤维物质中去除。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 volume and capacity factor were affected by micelle concentrations in the mobile phase。The partition coefficients of the oily substances between the fiber substrate and micelles （PイD2smイD2， between the fiber substrate and water （PイD2 swイD2）， and between micelles and water （PイD2 mwie D2） were determined with the chromatManagement treatment involving micellar mobile phases。P-D2 sm-D2 sw-D2 values for the oily substances were larger for the polyester system than for the cellulose system。有机硅和纤维基质在游离能量（-Δμ）之间的变化（2.9 - 3.3千卡/摩尔的聚酯，以及纤维素的4.3 - 4.5千卡/摩尔的变化，适当地建议说，有机硅物质在从聚酯中去除以外有很多不同的地方，这些结果类似于其他研究人员使用其他方法观察。这种色谱技术可能是有用的，用于调查在去除和重新沉积的有机质平衡物之间的动态平衡物，将一个织物基础物用于去除解决方案。

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.
