小应力下织物拉伸和弯曲性能对其湿态贴体性的影响

为了研究湿态下织物脱离皮肤时对皮肤的贴附性能，本文采用新型研发的织物湿态黏附仪对织物试样在湿态下对皮肤的贴服性能测试，得到黏附力，黏附距离和黏附功三个指标，并得到黏附曲线。对10种不同类型的织物试样的黏附曲线形状进行观察分析，总结出黏附曲线的共性特征，发现黏附曲线分为3个区域，每个区域对应不同分离过程。为探讨影响织物的湿态舒适性的力学因素，采用KES系统对织物试样测试其拉伸和弯曲性；同时测试得到相应试样在分离速度为15mm/min下的黏附曲线和黏附指标值；对数据进行分析，发现织物的拉伸功与最大黏附力大致呈正相关，而弯曲刚度恰好相反；最大黏附距离越大，黏附曲线越平坦。

Impact of fabric tensile and bending properties on adhesion propertyunder wet condition atlow tension

In order to study the adhesion property of fabric when it was seperated from skin in wet condition, the new developed wet fabric adhesion apparatus was used to test the adhesion property of fabric to skin in wet condition. There were three indices: adhesion force, adhesion distance and adhesion work. And a wet adhesion curve can be obtained from this method. Based on the observation and analysis of ten adhesion curves’ shapes of different kinds of fabric samples, it was concluded that adhesion curves had common characteristics. And it was found that the curve can be divided in to three parts and each part reflected different separation process. The KES system was adopted to test tensile and bending properties of fabric samples in order to study the impact of mechanics on wet fabric comfortability; meanwhile, adhesion data and curves were tested at the separation speed of 15mm/min. The results show that it is positive correlation between the tensile work and maximum adhesion force, opposite from the bending rigidity and the curve tends to be flatter with the longer adhesion distance.
