  • Pleatable nonwoven material and method and apparatus for production thereof
    Patent number: 10273611
    Abstract: A pleatable nonwoven material is provided, including thicker form-giving fibers and thinner fibers determining the filter effect, wherein the thinner fibers are incorporated largely homogeneously in the thicker fibers running in the direction along the surface of the nonwoven material and a distribution density gradient of the thinner fibers is established perpendicular to the surface of the nonwoven material such that the highest concentration of thinner fibers is in the region of the center or on one of the two outsides, wherein the thicker and thinner fibers are bonded together by solidification from the melted condition and are made from the same material.
    Type: Grant
    Filed: September 16, 2014
    Date of Patent: April 30, 2019
    Assignee: IREMA-FILTER GMBH
    Inventors: Anke Jung, Andreas Seeberger
  • Air filter medium combining two mechanisms of action
    Patent number: 9168471
    Abstract: An air filter medium consisting of a non-woven is provided, which is produced using a melting and spinning method and has a depth filter constituent and a surface filter constituent, wherein the air filter medium is configured such that it has long-lasting functionality owing to the depth filter constituent and can be substantially regenerated with a reverse pulse owing to the surface filter constituent.
