In this paper, we discussed the particle based mechanical model for numerical simulation of clothing pressure. Human body and clothing were represented as an elastic body by particle system, collision between human body and clothing was represented by impulse force based model. The two simulations were conducted to evaluate the validity of the suggested model. In the first simulation, clothing pressure on the elastic cylinder covered with cloth was predicted to evaluate the precision of static clothing pressure prediction. As a result, it was confirmed that it had the accuracy of 0.08 kPa, but there was a room for improvement to predict on the edge of cloth. Although it is considered that the mesh resolution (particle distance) caused the problem, it is important to decide a suitable mesh resolution for purpose because it is directly with calculation time. In the second simulation, we conducted the simulation that winding elbow with sleeve to evaluate the precision of dynamic clothing pressure prediction. As a result, it was observed that clothing pressure changed with elbow flexion. However it was not able to obtain the accurate result caused by numerical instability in the case of fast elbow flexion. It is considered that time step and collision model between clothing and human body on the simulation caused numerical instability. Improvement and implementation of the simulation considering whole body motion for dynamic clothing pressure prediction are our future work.

Poly (vinyl alcohol) (PVA) reacts with borate ions to give a thermoreversible gel. In this work, gel films (PVA-G) were successfully prepared by drying this gel or by soaking PVA films (PVA-O; crosslink-free PVA films) in a solution containing borate ions. On the other hand, the crosslinks formed in PVA-G can be removed by soaking PVA-G in an acid solution. The mechanical properties and structure of PVA-G were investigated by means of dynamic viscoelastic, wide angle X-ray diffraction, hot water resistance and thermogravimetric measurements, and were compared with those of PVA-O.The results of dynamic viscoelastic measurements show that PVA-G retains a high value in storage modulus up to ca. 200°C which are different from PVA-O. In addition, there appeared a mechanical dispersion around ca. 220°C. Wide angle X-ray diffraction patterns show that the crystallite size of PVA-G is smaller than PVA-O. The characteristic behaviors in viscoelasticity are explained by the presence of crosslinks and/or crystallite size. Hot water resistance of PVA-G was also found to be improved by the introduction of crosslinks.
