Method for Producing a Polyamide Nanofiber Product by Electrospinning, Polyamide Nanofiber Product, a Filter Medium with Polyamide Nanofiber Product, as well as a Filter Element with such a Filter Medium
In a method for producing a polyamide nanofiber product that contains PTFE particles, a spinning solution containing polyamide, PTFE, and a conductivity-increasing additive is provided and nanofibers are produced by electrospinning from the spinning solution. The conductivity-increasing additive is an acid-resistant additive; a surfactant additive; or an acid-resistant and surfactant additive and contains one or more organic salts. The polyamide nanofiber product with PTFE particles is used in filter media and is especially applied to a filter layer of cellulose or synthetic material.
