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.

通过对绝缘织物表面摩擦电荷向空气放电过程的分析，可以分析水分子与织物相互作用的物理状态。为了确定这一事实，在第一年就购买了一台性能优异的新品尝器，并用于测量变化衰减。这台新的测试仪也证实了同样的结果。第二年，对13种不同的织物进行了电荷衰减测量，其中包括具有防静电性能的新材料作为衬里。这些织物在温度和湿度控制箱中完全调节，并在恒温室内测量摩擦电荷衰减。将电荷衰减曲线分析为两个衰变过程。一种是受表面化学结构影响的快速放电过程，另一种是不受表面影响的慢放电过程。这一过程可以用织物表面存在的束缚水和自由水来理解。发现束缚水分子和自由水分子上的电荷是独立地从织物表面散射的。然而，这种对电荷衰变过程的解释必须深入讨论。
