An absorbent hygienic article for absorbing body fluids, the article including a liquid permeable topsheet, a backing layer and an absorbent core arranged between the topsheet and the backing layer, the topsheet and the backing layer being made from roll materials. The topsheet or an absorbent layer in the absorbent core is constituted by a cellulosic fibrous web, the fibres in the cellulosic fibrous web being constituted by a mixture of cellulose fibres including regenerated cellulose fibres or natural cellulose staple fibres and cellulose pulp fibres, the cellulosic fibrous web being a foam-formed, hydroentangled fibrous web.

Articles, such as sanitary tissue products, including fibrous structures, and more particularly articles including fibrous structures having a plurality of fibrous elements wherein the article exhibits differential cellulose content throughout the thickness of the article and methods for making same are provided.

The present disclosure relates to an absorbent fibrous web, in which the fibres are constituted by cellulosic fibres including cellulosic staple fibres and cellulose pulp fibres and the absorbent fibrous web is a foam-formed hydro-entangled fibrous web. The present disclosure further relates to a method of manufacturing such an absorbent fibrous web.

A process for foam forming webs is disclosed. The foam formed webs can be used as wiping products, such as industrial wipers, food service wipers, and the like. The web contains a mixture of cellulosic fibers and longer, strength building fibers. The web is foam formed and then subjected to one or more hydroentangling steps. After hydroentangling, the web is dried in a non-compressive manner.

The invention relates to a filter material for a smoking product, comprising a nonwoven material, wherein the nonwoven material is hydro-entangled, the hydro-entangled nonwoven material contains min. 50% and max. 90% wood cellulose fibres, min. 10% and max. 50% fibres from regenerated cellulose and less than 30% non-natural polymers, in relation to the mass of the hydro-entangled nonwoven material, and together the amount of wood cellulose fibres and fibres from regenerated cellulose make up at least 70% of the mass of the hydro-entangled nonwoven material, and the hydro-entangled nonwoven material has a density of min 100 kg/m.sup.3 and max. 300 kg/m.sup.3 and a thickness of min. 100 μm and max. 1000 μm. The invention also relates to a segment with the filter material, a smoking product and a production method.
