The needle punched fabrics are produced when barbed needles are pushed through a fibrous web forcing some fibres through the web, where they remain when the needles are withdrawn. If sufficient fibers are suitably displaced the web is converted into a fabric by the consolidating effect of these fibres plugs or tufts.
