Patent

CA 2309446

The present invention is generally directed to base webs that are creped after a bonding material has been applied to at least one side of the web according to a predetermined pattern. The base web disclosed in the present application is made from at least three fibrous layers. The outer layers of the web contain synthetic staple fibers for increasing the tensile strength and abrasion resistant properties of the web. In one embodiment, the middle layer can further contain hardwood fibers, such as eucalyptus fibers, which improves the wipe dry properties of the web.

De manière générale, l'invention concerne des tissus de base que l'on crêpe après avoir appliqué un matériau de liaison sur au moins un de ses côtés suivant un motif prédéterminé. Le tissu de base de la présente invention comprend au moins trois couches fibreuses. Les couches externes renferment des fibres discontinues synthétiques, qui améliorent les propriétés de résistance à la traction et de résistance à l'abrasion du tissu. Dans l'un des modes de réalisation, la couche intermédiaire peut renfermer en outre des fibres de bois dur, telles que des fibres d'eucalyptus, qui améliorent les propriétés d'essuyage du tissu.
