Patent

CA 2053088

A fabric is disclosed for supporting a web in a papermaking machine. The fabric includes a base which defines a first and a second side. The base includes a plurality of hydrophobic filaments, and a first layer of fibers is disposed contiguously relative to the first side with the first layer of fibers being applied onto the first side of the base. A second layer of fibers is disposed contiguously relative to the second side of the base with the second layer of fibers being applied, onto the second side of the base. At least one of the layers of fibers includes a mixture of hydrophobic and hydrophilic fibers. The layers and the base are combined such that the fabric has a low permeability permitting water to be absorbed thereby while inhibiting rewetting of the web.

Toile pour supporter un voile de fibres dans une machine pour la fabrication du papier. La toile comprend une base constituée de deux côtés. La base comprend un ensemble de filaments hydrophobes et une première couche de fibres appliquées sur le premier côté de la base. Une deuxième couche de fibres est accolée au deuxième côté de la base, la deuxième couche de fibres étant appliquée sur le deuxième côté de la base. Au moins une des couches de fibres contient un mélange de fibres hydrophobes et de fibres hydrophiles. Les couches et la base sont combinées de manière à ce que la toile présente une faible perméabilité, ce qui permet à l'eau d'être absorbée et ainsi d'éviter que le voile ne se mouille à nouveau.
