Porosity is an important characteristic of a filter textile, which affects permeability and retention properties. Determination of the inter-yarn and inter-fibre pore sizes of barrier textiles is also required to assess the filter behaviour of these textiles. In this study, a software tool was developed to detect the inter-fibre pore size distribution and pore size intensity of multifilament woven barrier fabrics using cross-section images. Fabrics were chosen according to their fabric construction parameters, such as the fabric index, weft yarn filament fineness and weft yarn structure (flat or textured).Microscopic cross-section images of weft yarns were taken, processed to binary images, and analysed with respect to the pore size distribution, number of pore lengths and pore intensity. It was also analysed how the fabric index; filament cross-section and filament fineness affect the inter-fibre pore lengths and separation level proposed. It was found that weft yarns with wider lengths and lower height showed wider inter-fibre pores. Inter-fibre pores decreased with a decrease in filament fineness. Moreover, the separation level proposed deviated from the 90% level depending on the fabric index. This deviation was very small in samples with reduced filament fineness and textured samples. The separation level proposed will be useful to understand the effect of fabric construction parameters to obtain targeted properties regarding inter-fibre and inter-yarn pore size.
Porowatość jest ważną cechą tkanin filtracyjnych, która wpływa na przepuszczalność i właściwości retencyjne. Niezbędne do oceny zachowania filtrów jest określenie wielkości porów w przędzy i między włóknami. W badaniu opracowano narzędzie programowe do określenia rozkładu wielkości porów między włóknami i ich intensywności z wykorzystaniem przekrojów poprzecznych w przypadku tkanin barierowych. Tkaniny zostały wybrane zgodnie z ich parametrami konstrukcyjnymi, takimi jak indeks tkaniny, próba włókna nitki i struktura przędzy wątku (płaska lub teksturowana). Wykonano mikroskopowe obrazy przekroju nitek wątku, przetworzono je na obrazy binarne i analizowano pod względem rozkładu wielkości porów, liczby długości porów i intensywności porów. Przeanalizowano również, w jaki sposób indeks tkaniny, przekrój poprzeczny włókna i drobnoziarnistość wpływają na proponowane długości porów międzywłókienkowych i poziom separacji. Stwierdzono, że pory między włóknami zmniejszyły się wraz ze zmniejszeniem rozdrobnienia włókien. Ponadto proponowany poziom separacji odbiegał od poziomu 90% w zależności od indeksu tkaniny. Odchylenie to było bardzo małe w próbkach o zmniejszonej próbie rozdrobnienia i teksturowanych.
