The nonwoven (1) comprises structural fibres (7, 8) and binding fibres (5, 6), said binding fibres (5, 6) at least partially consisting of a polymer with a lower melting point than the structural fibres (7, 8). Said nonwoven (1) is densified by needling on both sides to a given depth while leaving an undensified central region. A method for producing the nonwoven is also disclosed.</p> |
