摘要： The filter for gel shearing and particle filtration of molten polymer has a first layer of metal fibers of an average equivalent diameter between 8 and 65 μm. The cross-section of the metal fibers has two neighboring straight sides with an included angle of less than 90° and one or more irregularly shaped curved sides. The metal fibers have an average length of at least 6 mm. The metal fibers are bonded to each other by metal bonds; where the metal of the metal fibers of the first layer is the bonding agent forming the metal bonds. The filter has a second layer of metal fibers. The average equivalent diameter of the metal fibers of the second layer is smaller than the average equivalent diameter of the metal fibers of the first layer.

摘要： A mass of metal fibers, where the metal fibers of the mass have a discrete length. The cross section of the metal fibers has two neighboring straight lined sides with an included angle of less than 90° and one or more irregularly shaped curved sides. The metal fibers of the mass have an average equivalent diameter of the fibers of less than 100 μm. The metal fibers of the mass have a standard deviation between fibers of the equivalent fiber diameter less than 25% of the equivalent fiber diameter.

摘要： A filter membrane has at its flow in side a first metal fiber web, at least two metal fiber layers, and a fine and at least one coarser fiber layer. The fine fiber layer is located at the flow in side of the filter membrane and the at least one coarser fiber layer is located downstream of the fine fiber layer. The filter membrane has at its flow out side, a stack of one or more first two-dimensional metal structures with constant and regular openings. The filter membrane also has at least one set formed by a second metal fiber web and a stack of one or more second two-dimensional metal structure with constant and regular openings; the at least one set is provided in between the stack of one or more two-dimensional metal structures that are having constant and regular openings, and the first metal fiber web.
