Title: SPUN-BONDED FABRIC MATERIAL, OBJECT COMPRISING A SPUN-BONDED FABRIC MATERIAL, FILTER MEDIUM, FILTER ELEMENT, AND USE THEREOF
Abstract:
A filter medium (10) for filtering a fluid, in particular for use in an interior air filter (32), comprises a spun-bonded fabric material formed at least in part of multi-component segmented pie fibers (1) having at least a first synthetic component (2) and a second synthetic component (3). The multi-component fibers (1) are largely non-split, and in order to manufacture same, segmented pie filaments are spun in a spun-bonding process (S4) to form a spun-bonded fabric material (10). The segmented pie filaments then form the multi-component fibers (4), the first synthetic component (2) and/or the second synthetic component (3) being made in particular of a polypropylene.
