Definitions

  • a nonwoven fabric made of staple fibers and / or continuous fibers such as spunbond fibers and / or mixed with natural fibers such as pulp does not have a uniform distribution of the fibers in the longitudinal and transverse directions due to the manufacturing conditions.
  • the fibers are stretched substantially in the longitudinal direction of the fleece, so that in the transverse direction a lower strength after z. B hydrodynamic needling arises.
  • the invention has for its object to find a method of how a uniformly consolidated nonwoven and thus an overall increased consolidated nonwoven can be obtained over the surface in the two directions MD and CD.
  • the fleece is at least partially forced to reorient the fibers before, during and / or after a first hydrodynamic needling and / or a subsequent hydrodynamic needling across the width and then the fleece is subjected to a further water jet treatment.
  • the reorientation of the fibers can arise during lateral stretching, pressing and / or only surface treatments such as brushes or with water jets that are offset or shifted sideways. This gives the fleece a higher overall strength than would be possible without this reorientation of the fibers.
  • This treatment can also be carried out several times in succession. It is important to ensure that the fleece is uniform across the width, e.g. B. is stretched, which occurs in any case when the fleece is fully supported during stretching, brushing or pressing and the forces acting on the fleece attack uniformly across the width of the fleece.
  • Devices for this are known in the textile field for the treatment of fabrics and knitted fabrics.

Abstract

Un non-tissé de fibres discontinues composé d'une carde, ou d'autres non-tissés composés de filaments, présentent une rigidité plus importante dans le sens longitudinal que dans le sens transversal en raison des longueurs de fibres orientées longitudinalement après l'aiguilletage, l'aiguilletage hydrodynamique par ex. Ce fait peut être modifié lorsque le non-tissé pré-renforcé est soumis à une réorientation des fibres, par ex. lors d'un traitement d'étirage latéral au cours duquel les fibres entrelacées dans le non-tissé sont au moins partiellement réorientées, par ex. dans le sens transversal. Ensuite, les fibres ainsi réorientées sont soumises à un traitement de renforcement hydrodynamique supplémentaire afin de fixer les fibres dans leur nouvelle position. De cette façon, le non-tissé présente une rigidité plus importante qu'avant réorientation des fibres.
