A nonwoven fabric comprised of a self-sustaining pre-bonded web formed by carding together first relatively thin monocomponent fibers, second relatively thicker monocomponent fibers, and 1-5% bicomponent fibers with the low softening point component thereof bonding together the first, second and bicomponent fibers to form the self-sustaining web. Six to ten percent by weight of cured latex particles are disposed within the fabric and smeared on the outer surfaces of the fabric (54), the particles being cured in situ (80) to provide enhanced tensile strength to the fabric.
L'invention concerne un non-tissé composé d'une bande précollée indépendante formée par cardage de premières fibres monocomposants relativement fines, de secondes fibres monocomposants relativement épaisses, et de 1à 5 % de fibres bicomposées, le point de ramollissement basse température reliant toutes ces fibres entres elles pour former la bande indépendante. 6 à 10 % en poids de particules de latex durcies sont insérées dans le non-tissé et étalées sur les surfaces extérieures du non-tissé (54), les particules étant durcies sur place (80) de manière à conférer une résistance à la rupture au non-tissé.
