Absorption Ability of Odor for Wool as Clothing Materials

采用反相气相色谱法测定了各种探针在羊毛上的保留体积。这些探针是萜类化合物：β-蒎烯、费兰烯、柠檬烯、芳樟醇、柠檬醛和L-香芹酮，它们可用作香料和香精的原料。这些萜类化合物具有不同的官能团，保留体积（VR）与样品量呈线性关系。这一事实表明，羊毛纱线和探针分子之间的弱相互作用。极限保留体积（V_R^O）随探针极性的增大而增大，且与官能团类型密切相关，在V_G ^O对1/T（K）的关系图中，保留体积在所有探针中均呈线性关系。对于在所用温度范围内不发生变化的保持机制，曲线应呈线性。该直线段的斜率由 *Hi/R给出，其中 *Hi是探针在羊毛表面上的吸附热，R是气体常数。虽然极限比保留体积（Vg^O）的值略有变化，吸附热（*Hi）的计算值是独立的柠檬烯/羊毛系统的值。

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.
