Absorption Ability of Odor for Wool as Clothing Materials

用反相色谱方法测定了不同探针在羊毛上的保留体积。这些探针是萜类化合物：β-蒎烯、铁烯、柠檬烯、芳樟醇、柠檬醛和L香芹酮，可用作香料和香料的原料。这些萜类化合物各自具有不同的官能团，各体系的保留体积(V_R)与样品量呈线性关系。这一事实表明羊毛纱线与探针分子之间的相互作用很弱。极限保留体积(V_R^O)随探针极性的增加而增大，且与官能团的类型有很强的相关性，In_R^O与1/T(K)的关系图，即保留图显示了所有探针的线性关系。对于不随应用温度范围变化的保留机构，曲线图应该是线性的。直线段的斜率由*Hi/R给出，其中*Hi是探头在羊毛表面的吸附热，R是气体常数。对于柠檬烯/羊毛体系，极限比保留体积(Vg^O)值变化不大，但吸附热(*Hi)的计算值与其值无关。

Inverse gas chromatography was used to determine retention volumes for various probes on wool. These probes were terpenoids : beta-pinene, ferandrene, limonene, linalool, citral and l-carvone, which were useful as raw materials for flavors and fragrances. These terpenoids had various functional groups, respectively.The retention volumes(V_R) of all systems were linearly related with sample size. This fact indicated a weak interaction between wool yarns and probe molecules. The limiting retention volumes(V_R^O) increased with increasing the polarity of probes and strongly depended on the type of functional groups.A plot of in Vg^O against 1/T(K), that is, a retention diagram showed a linearity over the whole variety of probes. The plot should be linear for a retention mechanism which dose not change over the temperature range applied. The slope of this straight segment is given by *Hi/R, where *Hi is the heat of adsorption of probe on the wool surface and R is the gas constant. Although the values of the limiting specific retention volume(Vg^O) varied slightly, the calculated values of the heat of adsorption(*Hi) were independent of its values for limonene/wool systems.
