Date Dec. 22, 1994A composite nonwoven material comprises at least one layer (2) of a carded voile of hydrophobic thermoplastic fibers, the said fibers being partially disoriented in at least a proportion of the thickness of the voile so that a proportion of the said fibers has an angular orientation in relation to the main plane of the fibers of the said voile, and a layer (3) made of voile of nonwoven of noncarded type of hydrophobic thermo-plastic fibers, the fibers of at least one of the layers being chosen from fibers with a low melting point, two-component fibers, mixtures of such fibers with fibers of high melting point and fibers mixed with a binder or one face of the voile of one of the layers is coated with a binder, the layers being joined together by heat-melting. |
