机织物与皮肤间摩擦特性的测试方法

Measurement for Friction between Human Skin and Woven Fabric

  • 摘要: 为了便于研究织物与人体皮肤间的摩擦性能,作者模拟织物与皮肤的摩擦行为,在现有负荷-伸长测试仪的基础上,研制改造出一台用于测量织物与皮肤间摩擦特性的测试仪.实验发现,在同一组摩擦试验中,首次摩擦试验的曲线明显低于其后的摩擦曲线,而且动摩擦力的波动性较后者大.为保证该仪器的测量数据客观有效,进行了重现性和可比性对比试验,结果表明该仪器在相同测试条件下测得的摩擦信号重现性较好,不同织物和皮肤间的摩擦试验结果具有可比性.同时为了归纳出相对稳定的试验条件(如张力?摩擦速度?试样宽度),选择4种规格不同的机织物与皮肤进行对比试验, 根据摩擦信号的稳定性和实际测试条件, 推荐了常规机织物的基本测试参数, 其中张力为2N , 摩擦速度为5 0 0m m/ m i n , 试样宽度为1 0c m .

     

    Abstract: In order to investigate the friction between human skin and fabrics , a simulating tester based on strength - elongation tester was developed . It was found that the first friction curve was obviously lower than that of the subsequent curves in a set of trial , and the fluctuation of dynamic friction for the former was larger than that of the latter . Experiments for reproducibility and comparability were carried out to ensure the data were effective and objective. The results showed that reproducibility of the friction signal was satisfied and the friction force was comparable among different fabrics and skin . In order to generalize the relatively steady conditions ( tension , friction speed , sample width ) , comparative analysis were carried out among four kinds of woven fabrics . According to the stability of signal and actual test conditions , the basic test parameters for conventional woven fabric were recommended as follows : the appropriate tension 2N , sliding speed 500 mm / min , and the sample width 10 cm
