Support pantyhose, consumption of which has recently increased, have been advertised as follows; for example, support pantyhose make women's legs beautiful or slim silhouette, or make the swelling of legs lower. This paper aims to comfirm whether the effects of support pantyhose on silhouette or swell of lower limbs are true or not. Three kinds of pantyhose, the clothing pressure of which is high, middle and low, were used as samples. An experiment on silhouette of lower limbs were conducted by female students as subjects. An experiment on swelling of lower legs were conducted by working women as subjects with standing posture amd little walking actions at a constant working position in a pantyhose factory. The results were obtained as follows;
1) By wearing hard-support pantyhose, maximum thigh girth and foot girth largely decreased, but ankle girth considerably increased. Because the ankle girth which most young Japanese women want to be looked slim or slender increased considerably, there were little effects of the pantyhose on silhouette of lower limbs.
2) When the clothing pressure of pantyhose is higher, the swelling of lower legs became lower. However, it could be suggested that support pantyhose having higher clothing pressure was undesirable to women of over middle age.

The diffusion of oily materials into polyester (PET) film has been investigated by the dynamic viscoelastic measurement of the films heat-treated with several model components in human sebum. The summary is as follows:
1) Loss modulus peaks of α -dispersion of PET films shifted to lower temperature side with heat treatment (150°C, 30min) with fatty acids (oleic acid and stearic acid) and alcohols (stearyl alcohol, cholesterol, monostearin and glycerol) . The results suggest that these fatty acids and alcohols diffuse into the film with the treatment.
On the other hand, fatty acid esters (triolein, tristearin and cholesterol oleate) and hydrocarbons (squalene, squalane and liquid paraffin) did not affect α-dispersion peak. The results indicate that it is difficult for these nonpolar compounds to diffuse into the film.
2) In the presence of glycerol, α-dispersion peak temperature reduction occurred at a lower treatment temperature, and another reduction was added for fatty acid or alcohol treatment.
