To clarify the deformation on the surface of the back affecting aesthetics when wearing a brassiere, the backs were measured using 3D body scanners. The subjects were two women aged 30s and 60s years. They each wore several kinds of brassieres. The deformation of the body surface when wearing a brassiere reached a maximum around the posterior axillary. Then, the distance (L) from a vertical line, which is intersecting the coronal plane passing through the shoulder point and the midsagittal plane, to the body surface at the vertical cross section through the posterior axillary point was measured. Then, the deformation amounts (δ), which were defined as the difference of the distance (L) while wearing a brassiere and when nude was examined. The δ depended on clothing pressure at the upper and lower edges of a brassiere. This tendency was stronger for elderly people with a soft body surface. A multiple regression analysis was performed, and it was found that the clothing pressure and the amount of compressive deformation of the body surface (E30) under a load of 0.294N were important factors for determining the δ. It was found that the δ is an important indicator for aesthetic evaluation.

This study aimed to assess the effect of processed fabric with eggshell membrane and phospholipid polymer on the thermal performance when wearing. The moisture regain, water absorption, and heat and water transfer were evaluated using the processed fabric, with the brank fabric as a control. Wearing tests were also conducted using T-shirts made of those fabrics. An improvement in the moisture regain and water absorption of the processed fabrics led to an increase in the amounts of moisture emission and latent heat loss. In the wearing tests, the temperature and humidity within the clothing, as well as the sweating rate, decreased when wearing the processed garment; significant differences were observed during the recovery period. However, the processed fabrics did not affect the heart rate. Correlation analysis between the measurement items revealed that the humidity and temperature within the clothing had a significant correlation with the sweat rate and heart rate during the walking and recovery periods. Subjects who wore the processed shirts felt significantly lesser humid. Thus, it was concluded that the processed fabrics with high hydrophilicity enhanced the thermal performance when wearing. However, it has also been found that it is necessary to impart higher hydrophilicity to fabrics in order to have positive effects on heart rate and comfort feeling.
