Abstract: The present invention relates to a cleanable 3D filter medium, a method for manufacturing said filter and the use of the filter.
The filter medium according to the present invention comprises at least one textile layer being a non-woven of synthetic, organic polymer fibers. The nonwoven having an embossed pattern in which the nonwoven having at the non-embossed area a thickness D and at the embossed area a thickness d and the ratio d/D is the compression factor CF, said compression factor CF being in the range 0.2≤FC≤0.5.
The filter medium according to the present invention can be cleaned and are used in filter systems for air/gas and liquid filtration, particularly in the motor vehicle industry, in air conditioning systems, passenger compartment filters, pollen filters, clean room filters, domestic filters, and as oil filters and hydraulic filters, thus removing solids from air/gas and liquids.

Abstract: Provided is a nonwoven material as base interlining in sarking, roofing, or coated sealing membrane with an improved isotropy of the material. The nonwoven material comprises a spunbond nonwoven of polyester filaments. The nonwoven has a tensile strength ratio of the specific tensile strength MD to the specific tensile strength CD between 1 and 1.5. The nonwoven material for bituminous roofing membranes has a preferential thermal dimensional stability (TDS), as well as a preferential thermal shrinkage behaviour. Further, a method is provided to manufacture a nonwoven material with an improved mechanical homogeneity. In addition, a bituminous roofing product comprising a nonwoven material according to the invention is provided. The bituminous roofing product is preferably a bituminous roofing membrane.
