Abstract
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 hydrophillic 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 weight-% 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.

Nonwoven material produced by hydroentanglement of a wet-laid or foam-formed fibre web, comprising:
- a mixture of short plant fibres, where a major portion of the short plant fibres presents a fibre length below 5 mm, and long hydrophillic plant fibres in the form of elementary fibres where a major portion of the long hydrophillic plant fibres presents a fibre length which is at least 10 mm, wherein the long hydrophillic plant fibres is at least 1% weight of the fibre weight,
- the fibres of said nonwoven material comprise only natural fibres, and
- the short plant fibres and the long hydrophillic plant fibres have been 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 adsorbing material.
