Processing of needle-punch material with the examined method increases the deformation resistance and does not affect the strength characteristics. The increase in the deformation resistance is a function of the bulk density of the initial needle-punch material. The change in the porosity during processing of the material is a function of the mobility and orientation of the fibres.
