Abstract (en)
[origin: WO2019192837A1] The invention relates to a method for producing a textile fabric that has triboelectrically charged fibers, and a textile fabric. At least two separate nozzle bars or at least one multi-polymer nozzle bar is used to produce fibers from different polymers, the polymers having a suitably large distance in the triboelectric series. In the process, the fibers produced from the polymers are mixed and triboelectrically charged at least in some regions. Alternatively or additionally, the fibers are triboelectrically charged by an uncomplicated post-treatment. Filters having quality factors greater than 0.2 can be produced using the textile fabric.
