CA 2264180

The invention is lyocell fiber characterized by a pebbled surface as seen at high magnification and having a variable cross section and diameter along and between fibers. The fiber is produced by centrifugal spinning, melt blowing or its spunbonding variation. The fibers can be made in the microdenier range with average weights as low as one denier or less. The fibers have inherently low gloss and can be formed into tight yarns for making fabrics of very soft hand. Alternatively, the fibers can be formed into selfbonded nonwoven fabrics.

Fibre lyocellulaire caractérisée par une surface granuleuse révélée par un fort grossissement, présentant une section transversale et un diamètre variant sur la longueur des fibres et d'une fibre à l'autre. La fibre est obtenue par filage centrifuge, par fusion-soufflage ou par la variation "spunbonding" de cette dernière technique. Les fibres peuvent être réalisées ä des finesses de l'ordre du microdenier, leurs poids moyens étant égaux ou inférieurs à un denier. Ces fibres sont naturellement peu lustrées et se prêtent à la fabrication de fils serrés permettant de réaliser des tissus ou toucher très doux. Ces fibres se prêtent également à la fabrication de matériaux non tissés auto-agglomérés.
