| Research Abstract |
Physical state of water molecule interacting with the fabric can be analyzed by the analysis of discharge process of triboelectric charges into the air from insulating textile fabric surface. In order to make this fact sure, in the first year a new taster having excellent performance was purchased and used for measuring the chage decay. The same result was confirmed by this new tester. In the second year the charge decay measurement was carried out for 13 different fabrics including the new material having anti-electrostatic property for a lining. These fabrics were completely regulated in a temperature and humidity control box and measured for triboelectric charge decay in a thermohygrostat room. The charge decay curves were analyzed into two decaying processes. The one process is a fast discharging process effected by the surface chemical structure and the other is a slow discharging process disregarding the surface. This process can be understood with the bound and free water existing in the fabric surface. It was found that electric charges trapping on bound and free water molecules are scattered from fabric surface independently. However, this interpretation for charge decaying processes must be discussed deeply.
