  • Filter medium, method for producing same, and use of the filter medium in a filter element
    Patent number: 11266935
    Abstract: A filter medium has a substrate layer and a nanofiber layer arranged on the substrate layer. Adhesive fibers are laid onto the nanofiber layer and connect the nanofiber layer with the substrate layer. The nanofiber layer is located between the substrate layer and the adhesive fibers.
    Type: Grant

  • Method for producing a polyamide nanofiber product by electrospinning
    Patent number: 8801998
    Abstract: 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.

  • Method and system of determining the fiber diameter distribution of a fibrous media
    Patent number: 8594382
    Abstract: A method and system of determining fiber diameter distribution of a fibrous media is disclosed. The method includes providing at least one digital image representative of the fibrous media, pre-processing the images, binarizing the images, generating virtual lines on the image, solving for fiber fringe points on each of generated line, solving for fiber center points as a mean of the fringe points, generating and growing measurement circles about the fiber center points, repositioning circles and center points to avoid fiber intersections, resizing the repositioned measurement circles to intersect the opposing fringes, and calculating fiber diameters and fiber spacing.
