Abstract

See full text

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.
