纺织品负离子性能检测方法研究

摘要

The testing methods (friction method and standing method) of negative textiles were introduced. The effects of friction time and testing distance on the testing results were studied. The results showed that the generation amount of negative ion increased with the increase of friction time and testing distance, and up to the maximum value and then dropped down, which indicated that the generation of negative ion had saturation value, and would not infinitely increase with the sustained action of external physical stimulation. The optimal friction time was 10s and testing distance was 2 cm.%介绍了纺织品中负离子性能的检测方法(摩擦法与静置法),讨论了摩擦时间及测试距离对测试结果的影响.结果表明:负离子发生量随摩擦时间和测试距离的变化趋势都是先增加,达到最大值后下降,说明负离子的发生特性具有饱和性,不会随外界物理刺激的持续作用而无限增加.优化的摩擦时间为10s、测试距离为2 cm.
