Abstract
The volume-mass properties of unwoven fibrous needle-pierced materials in and outside of the zones created as a result of the action of needles were calculated. The properties were determined using a volume approach. Equations were derived for calculation of the masses, the volume and mass concentrations of all and type 1 fibers, and other properties in the regions mentioned. Both single and multiple needle piercings were considered. A program was developed to carry out the indicated calculations.
