The paper is concerned with some fundamental aspects of filtration of molten polymers, used in the synthetic fibre industry. The process of filtration of spinnable polymers is of great importance to the quality of the fibres produced. Because of the leading position of polyester and polyamide fibres in the world production of man-made fibres, we investigated the rheological properties and flow through granular beds of molten poly (ethylene terephthalate) — PET, and polycaproamide — PA6.
