feinmaschiges

Feinmaschiges is a German adjective used in technical language to describe a fabric, screen, or net with a particularly small mesh opening. It is commonly applied to textiles, metal meshes, and filter materials when a high degree of particle retention is required. In product catalogs one finds phrases such as feinmaschiges Metallgewebe, feinmaschiges Filtergewebe, or feinmaschiges Netz, indicating small apertures and high density of the weave or weave-like structure.

Dimensions and terminology: The size of the openings is specified as mesh count or aperture size. Mesh count expresses the number of openings per unit length, and openings typically range from roughly tenths of a millimeter down to the micrometer scale in specialized membranes. In membranes and sieves, pore sizes are often given in micrometers or nanometers, depending on the material and standard.

Manufacture and materials: Feinmaschige Gewebe can be produced by weaving (as fine wire cloth), knitting, or by producing perforated sheets and filter fabrics. Materials include stainless steel, brass, copper, aluminum, and synthetic polymers such as polyester, nylon, or PVDF. The choice depends on chemical compatibility, temperature resistance, and mechanical demand.

Applications: They are used for filtration and separation in chemical, pharmaceutical, and food processing, air and liquid filtration, micron-scale sieving, protective gratings, and optics or electronics where small particle exclusion is needed.

Performance and considerations: Fine meshes exhibit higher flow resistance and are more susceptible to clogging and mechanical wear. In design, factors include pore size, porosity, wire or fiber diameter, weave pattern, and material properties. Careful selection ensures adequate strength and chemical compatibility.
