摘要
The water-jet triboelectric charging technique has been widely used in China to improve the filtration efficiency of meltblown nonwoven fabric. However, there are few reports on research about water-jet triboelectric charging in the literature. In this paper, influences of the conductivity and pH of water on the filtration efficiency of meltblown nonwoven fabrics were investigated. The surface charge potential and its distribution of water-jet triboelectric charged meltblown nonwoven fabrics were characterized from microscopic and macroscopic aspects by using a bio atomic force microscope and electrostatic voltmeter. The charge stability was analyzed by using the thermally stimulated discharge technique. Meltblown nonwoven fabrics were water-jet triboelectric charged repeatedly in order to explore the charging mechanism. It is found that meltblown nonwoven fabrics with high filtration efficiency were developed by water-jet triboelectric charging treatment and the electrical conductivity of water had more influence than the pH on the filtration efficiency of triboelectric charged meltblown nonwoven fabrics. In addition, a possible mechanism of water-jet triboelectric charging is proposed based on experiments and characterizations.
