Multilayer porous fabric

摘要: A multilayer porous fabric comprises a core provided with plurality of suitably located hook means structures on at least one its surfaces. At layer nonwoven fibrous batt, pre-needled to desired density, is attached by entanglement onto the pressing and batt together, so that engage entangle sufficient fibers from anchor reliably without further needling. The then ready for use processing can be handled before use, example in preparation installation papermaking machine press section. may formed weaving or as an extruded sheet. Compressive loads applied enhance level means.
