Weave and construction parameters of high density woven filter fabrics influence the pore morphology, which directly affects the functional properties such as permeability and retention. It is established that the morphology of multifilament woven filter fabrics comprises of meso and micro pores and, furthermore, their permeability can be tailored within suitable limits by adjusting the weaving machine, weave pattern and yarn type. It is known that the pore morphology will change due to mechanical loads, which occur during use, for instance. First, the change in morphology of the meso and micro structure is due to the transversal contraction of the yarns. Second, it changes since the overall textile structure deforms. This leads to a change of permeability and retention properties.

In this work, we present a comparative experimental and numerical study to reveal the change of permeability and barrier properties of filter fabrics under tensile stress...
