A filter medium () for filtering a fluid, in particular for use in an interior air filter (), comprises a spun-bonded nonwoven formed at least in part of multi-component segmented pie fibers () having at least a first plastic component () and a second plastic component (). The multi-component fibers () are largely non-split, and in order to manufacture same, segmented pie filaments are spun in a spun-bonding process (S) to form a spun-bonded nonwoven (). The segmented pie filaments then form the multi-component fibers (), the first plastic component () and/or the second plastic component () being made in particular of a polypropylene.

Filter medium, filter element and use thereof and filter arrangement

An apparatus for making a nonwoven fabric from thermoplastic fibers has a spinneret for spinning fibers into continuous filaments and a cooler for cooling the filaments. The cooled filaments are then deposited on a conveyor to form a nonwoven web. A first consolidator surface treats the nonwoven web with a hot fluid or hot air as it is conveyed on the conveyor. A second consolidating downstream of the first consolidator has a dual-belt furnace in which the nonwoven web is passed between two circulating belts or continuous belts for surface treating the nonwoven web with a hot fluid or hot air and for applying surface pressure can be applied to the nonwoven web at the same time.

Spun-bonded fabric material, object comprising a spun-bonded fabric material, filter medium, filter element, and use thereof

The invention describes a filter medium (), in particular for an air filter, in particular an interior air filter or for a fuel cell, including at least three active layers: The invention further discloses a filter media body including the filter medium; a filter element including the filter media body or the filter medium; an air filter including the filter element or the filter media body or the filter medium, and a production method for producing the filter medium.

Filter medium

The invention relates to a method for producing a nonwoven fabric from fibres, wherein the fibres are spun by means of at least one spinneret, are cooled and then deposited on a collection device to form a nonwoven web. The nonwoven web undergoes hot fluid bonding during at least two consecutive bonding steps. In a first bonding step, the surface of the nonwoven web is subjected to a hot fluid and, in a second bonding step, the surface of the nonwoven web is also subsequently subjected to a hot fluid and, in addition and at the same time, surface pressure is exerted on the nonwoven web.

Making a nonwoven from fibers

A filtering device features a carrier medium and activated carbon stratum as adsorbent and having a sealing closing over or sealing longitudinal and width sides of the activated carbon stratum all-around a periphery of the activated carbon stratum.

Filtering device, in particular for the air to be supplied to a fuel cell

The invention relates to a filter element (), including a filter body () with a self-contained exterior side () which surrounds a self-contained interior side (), at least one filter medium () being disposed between exterior side () and interior side () and the filter body () including at least in some areas at least one winding layer () with at least one adsorbent. The invention relates furthermore to a filter system () with a filter element () with a filter body () with a self-contained exterior side () which surrounds a self-contained interior side (), at least one filter medium () being disposed between exterior side () and interior side (), the filter body () including at least in some areas at least one winding layer () with at least one adsorbent.

Filter element, particularly air filter element, and filter system having a filter element

A filtering device features a carrier medium and activated carbon as adsorbent which is immobilized due to the addition of adhesive.
