In this paper, the influence of fabric structure, weft density, end spacing and yarn fineness on the dielectric constant of polyester woven fabrics was studied. The results show that at low frequencies, the dielectric constant of fabric was clearly affected by the processing parameters; when the organisation of the fabric is plain i.e. the warp density is 140/10 cm, weft density 140/10 cm and yarn linear density 32 tex, the absorbing performance of polyester woven fabrics is at its best. At higher frequencies, the effect of the varying parameters on the dielectric constant of the fabrics can be neglected. Polyester woven fabrics have better EM absorbing properties for these parameters. This study offers a new theoretical basis for the development of EM absorptive fabrics.

Badano wpływ struktury tkaniny (gęstości wątku i osnowy oraz masy liniowej przędzy) na dielektryczną stałą poliestrowych tkanin. Wyniki wykazują, że przy niskich częstotliwościach stałe dielektryczne w wyraźny sposób zależą od parametrów procesu tkania. Natomiast przy wyższych częstotliwościach wpływ struktury jest znacznie mniejszy, a nawet może być pomijany. Stwierdzono, że tkaniny poliestrowe mają dobre właściwości absorpcyjne pola elektromagnetycznego. Badania stwarzają nowe podstawy teoretyczne dla opracowywania tkanin absorbujących pole elektromagnetyczne.
