POROSTAR FILTER® are often used for the fabrication of Polyester-Filaments and Micro-Filaments.

POROSTAR^® XL-Filters have an extremely large pore volume consisting of a large number of woven wire cloth layers with square aperture widths that are arranged over the specific filtration layer. The individual woven wire cloth layers are bonded together as one stable filtration layer via sintering.

The edge is formed by a stainless sheet steel ring that, in combination with aluminium flat packings, creates a complete sealing.

Depending on the individual usage, the filter layer consists of 15 up to 25 woven wire cloth layers. The pore sizes of the filtration layers range between 20 and 5 micrometers. The melt passes through the porous filtration layer, arrives at the spinneret nozzle with a high degree of homogeneity and is ideally suited for the spinning process.
