摘要： The invention relates to a multi-layer composite for use in an air filter, comprising at least one upstream ply and a support ply that is connected to the upstream ply. The upstream ply is made of a non-woven fabric and has a finer porosity than the support ply. The aim of the invention is to form and further develop a multi-layer composite for use in an air filter, in particular in a filter bag in such a manner that the upstream ply can be connected in a stable and economical manner to the support ply. The invention is characterised in that the upstream ply is embodied as a spun bonded non-woven, the continuous filaments of which are at least partially twisted or interwoven with the support ply.
