A composite nonwoven material with a high liquid flow-through rate and excellent resistance to secondary wetting and fuzzing. The composite nonwoven material includes at least one layer (2) of a card web of hydrophobic thermoplastic fibres which are partially disoriented in at least a part of the web thickness so that some of said fibres are at an angle to the main fibre plane in said web, and a layer (3) of a non-card nonwoven web of hydrophobic thermoplastic fibres. The fibres in at least one of the layers are selected from low-melting point fibres, bicomponent fibres, mixtures of such fibres with high-melting point fibres, and fibres mixed with a binder, or one side of the web of one layer is coated with a binder and the layers are joined together by hot melt bonding. The material may be used in absorbent sanitary articles.

Matériau non-tissé composite présentant une vitesse élevée de traversée par les liquides, une excellente résistance au remouillage et au peluchage. Le matériau non-tissé composite comprend au moins une couche (2) d'un voile cardé de fibres thermoplastiques, hydrophobes, lesdites fibres étant partiellement désorientées dans au moins une partie de l'épaisseur du voile pour qu'une partie desdites fibres ait une orientation angulaire par rapport au plan principal des fibres dudit voile, et une couche (3) en voile de non-tissé de type non-cardé de fibres thermoplastiques, hydrophobes, les fibres d'au moins une des couches étant choisies parmi les fibres à bas point de fusion, les fibres bi-composants, les mélanges de telles fibres avec des fibres à point de fusion élevé et les fibres mélangées avec un liant ou une face du voile d'une des couches est enduite d'un liant, les couches étant réunies entre elles par thermofusion. Application aux articles d'hygiène absorbants.
