SANITARY TAMPON
A sanitary tampon that includes a body of generally cylindrical shape provided with a rounded front end in the insertion direction of the tampon and with a rear end from which an extraction cord protrudes; the body including an absorbent core, rectangular, with two major sides and two minor sides, covered with an absorbent sheet of non-woven fabric, and wound in the longitudinal direction and pressed together with said absorbent sheet, its major sides being oriented towards the front and rear ends of the body of the tampon and the tampon being made entirely of natural materials.
AN ABSORBENT HYGIENIC ARTICLE FOR ABSORBING BODY FLUIDS
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.
ABSORBENT FIBROUS WEB
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.
Absorbent hygienic article for absorbing body fluids

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.
ELASTIC DIAPER ELEMENT
An elastic diaper element that includes an elastic layer (1) and at least one layer (2) made of a nonwoven. The elastic element has connection regions (5) between the elastic layer (1) and the non-woven layer (2). The connection regions (5) extend in a preferred direction. The non-woven layer (2) is wavy when the diaper element is in the unstretched condition in order to provide regions (6) as a reserve allowing stretching. The connection regions (5) have an oscillating shape along their extent.
AN ABSORBENT HYGIENIC ARTICLE FOR ABSORBING BODY FLUIDS
An absorbent hygienic article for absorbing body fluids, the article including a liquid absorbent top layer and a backing layer, the top layer and the backing layer being made from roll materials and being joined together. The top layer is constituted by a cellulosic fibrous web, the fibres in the cellulosic fibrous web being constituted by a mixture of cellulose fibres, the mixture including regenerated cellulose fibres or natural cellulose staple fibres and cellulose pulp fibres, the cellulosic fibrous web being a foam-formed, hydroentangled cellulosic fibrous web.
Nonwoven material and a method for producing nonwoven material
The present invention relates to a nonwoven material for use as an absorbent wiping material produced by hydroentangling of a substrate web comprising at least one layer of fibers selected from amongst synthetic fibers, regenerated fibers and natural fibers, wherein the nonwoven material (1) has a base level h.sub.0 with protuberances (2, 3) on one side, wherein the protuberances (2, 3) form at least a first and a second surface structure respectively in the form of first (2) and second (3) protuberances from the base level h.sub.0, wherein the first protuberances (2) have a height h.sub.1 from the base level h.sub.0 and the second protuberances (3) have a height h.sub.2 from the base level h.sub.0, where h.sub.2 is higher than h.sub.1, and each of the second protuberances (3) occupies an area of the surface of the base level at least 4 times greater than each of the first protuberances (2). The present invention also relates to a method for producing a nonwoven material (111), wherein hydroentangling of a substrate web (101), which comprises natural fibers having a length of less than 10 mm, takes place on a surface-shaped carrier device (109) containing holes which form at least a first and a second pattern in the form of first and second holes respectively, wherein the second holes are at least 4 times larger than the first holes.
THREE-DIMENSIONAL NONWOVEN MATERIALS AND METHODS OF MANUFACTURING THEREOF
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a method can include providing a precursor web that includes a plurality of fibers and transferring the precursor web to a forming surface having a plurality of forming holes. The method can also include directing a plurality of pressurized fluid streams of entangling fluid in a direction towards the precursor web on the forming surface to move at least some of the fibers into the plurality of forming holes to create a fluid entangled web. The method can further include removing the fluid entangled web from the forming surface such that the at least some of the fibers moved into the plurality of forming holes provide a plurality of nodes. The plurality of nodes can have an anisotropy value greater than 1.0 as determined by the Node Analysis Test Method.
Process for making fluid-entangled laminate webs with hollow projections and apertures
The present invention is directed to a process and apparatus for formation of a fluid-entangled laminate web. The laminate web includes a support layer and a nonwoven projection web having a plurality of projections which are preferably hollow. The laminate web also includes a plurality of apertures interspersed with the projections. As a result of the fluid-entangling process, entangling fluid is directed through the support layer and into the projection web which is situated on a forming surface. The force of the entangling fluid causes the two layers to be joined to one another and the fluid causes a portion of the fibers in the projection web to be forced into openings present in a forming surface thereby forming the hollow projections. The force of the entangling fluid also causes the fibers of the two layers to be moved around protrusions present in the forming surface thereby forming the apertures.
NONWOVEN AND ABSORBENT ARTICLES CONTAINING THE SAME
The present disclosure relates to an absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and an intermediate layer disposed between the topsheet and the absorbent core, wherein the intermediate layer comprises a nonwoven which comprises a plurality of apertures, absorbent fibers, and ultrafine fibers. The nonwoven comprises the ultrafine fibers of about 3% to about 35% by weight of the nonwoven, and at least most of the plurality of apertures have a hydraulic diameter in the range of about 600 μm to about 4500 μm.
