Nonwoven material produced by hydroentanglement of a wet-laid or foam-formed fibre web. The material comprises a mixture of short plant fibres, in particular pulp fibres, and long hydrophilic plant fibres, where the major portion of the fibres presents a fibre length which is at least 10 mm, whereby the portion of long fibres is at least 1 wt.% of the fibre weight. The fibres were mixed with each other in the presence of a dispersing agent which allows a uniform fibre formation, in a wet-laid or foam-formed fibre web which has been hydroentangled with sufficient energy to form a compact absorbing material.

Non-tissé produit par liage par jets d'eau d'une nappe de fibres formée par voie humide ou au moyen d'un agent moussant. Ce non-tissé comprend un mélange de fibres végétales courtes, en particulier des fibres de pâte, et de fibres végétales hydrophiles longues, la majeure partie de ces fibres présentant une longueur d'au moins 10 mm, et la partie composée de fibres longues constituant au moins 1 % en poids du poids des fibres. Ces fibres sont mélangées les unes aux autres en présence d'un agent de dispersion qui permet un agencement régulier des fibres sous forme de nappe obtenue par voie humide ou au moyen d'un agent moussant, qui a été liée par jets d'eau avec une énergie suffisante pour former un matériau absorbant compact.
