摘要：
A method for imparting an electrostatic charge to a nonwoven fibrous web 20. The fibrous web 20 is wetted with a wetting liquid 24, followed by being saturated with an aqueous polar liquid 30 and drying 31. The resulting dried product is an electret article 43 that could be used as an air filter in, for example, a respirator 50.
