U ovom radu ispitivana je morfologija vlakana otpadnih materijala i njihov uticaj na fenomen pakovanja i svojstva filtracionog sloja u koalescerima. Ispitivano je devet otpadnih materijala. Skenirajućom elektronskom mikroskopijom utvrđeno je da su površine svih vlakana glatke, dok se poprečni presek razlikuje od kružnog, pravougaonog do nepravilnog. Vlakna kružnog poprečnog preseka imala su prečnike u opsegu od 12±0,8 do 40±4 µm, dok su vlakna polipropilenskih vreća i vlakna sunđera od nerđajućeg čelika bila trake, širine 452±11 i 1001±14 µm, redom. Takođe, je primećeno da su poliuretanska vlakna povezana formirajući sunđerastu strukturu, dok su vlakna polietilen tereftalata samo na nekim mestima međusobno povezana. U ovom radu ustanovljena je eksperimentalna zavisnost poroznosti sloja od permeabilnosti sloja za sve ispitivane materijale, što omogućava formiranje sloja vlakana željene permeabilnosti. Izuzetak je sloj formiran od vlakana polipropilenskih vreća koja su najvećih dimenzija tako da je ovaj sloj pokazao različitu zavisnost poroznosti od permeabilnosti sloja u odnosu na ostale ispitivane materijale.
