A fibrous structure exhibits an absorbency time of equal to or less than 1.5 s and exhibits an antimicrobial effect.

Fibrous structure exhibiting an antimicrobial effect

An intermediate laminate product includes a first paper layer including lignocellulose fibers, and a dry coating layer applied to one surface of the first paper layer, the coating including expandable microspheres having an expansion temperature (T), at least one polysaccharide, and a plasticizing additive which is capable of forming a thermoplastic blend with the polysaccharide. An expanded laminate structure includes the intermediate laminate product and a second paper layer comprising lignocellulose fibers, which is attached to the dry coating by heat lamination. A liquid packaging board includes the expanded laminate structure and a liquid barrier layer. A process for forming the expanded laminate structure includes applying a second paper layer to the coating of the intermediate product at a second temperature (T), which is above the expansion temperature (T) of the microspheres, whereby the microspheres expand, and at which the plasticizing additive causes plasticizing of the polysaccharide, to form a thermoplastic blend.

Intermediate laminate product, an expanded laminate structure, and process manufacturing thereof

The present invention relates to an odor control material consisting of a water-insoluble particulate odor control agent and a thermoplastic water-soluble carrier matrix encapsulating the odor control agent. The carrier matrix dissolves when in contact with an aqueous solution, such as urine and the odor control material is obtained by means of thermoforming. The invention relates also to a method for the preparation of the odor control material and the use of the odor control material in absorbent products. The present odor control material minimizes dusting problems caused by particulate odor control agents in production processes.

A superabsorbent polymer composite including superabsorbent polymers and cellulosic nanofibrils having a diameter equal to or less than 100 nm. The composite may be in the form of particles or a foam. Methods for producing the composite and absorbent articles including the superabsorbent polymer composite are also provided.

The invention concerns the use of a fiber modified with functions capable of interacting with microbial cell wall proteins for immobilizing micro-organisms in hygiene products. Those functions are particularly capable of interacting with anionic groups and amine groups, and are especially cationic groups and aldehydes, respectively. The fibers may be synthetic or cellulosic. Also hygiene products containing these fibers are described.

Bacteria trapping fibrous material

An absorbent article has two side edges (), two end edges (), a liquid-permeable surface layer (), a liquid-tight surface layer (), and an absorption body () arranged between the surface layers (). The absorption body () includes at least one intermediate storage part () arranged along a side edge (), in direct contact with a liquid transfer part (). The liquid transfer part () has a higher liquid affinity than the intermediate storage layer, so the liquid transfer layer drains from the intermediate storage part () better than the intermediate storage part () drains liquid from the liquid transfer part ().

Absorbent article with improved liquid-handling ability

The present invention relates to a method of producing polysaccharide fibres (), wherein the polysaccharide is dissolved and the solution is sprayed into a bath () which contains a water-miscible organic solvent and a cross-linker. The invention also relates to a polysaccharide fibre () produced by the method, and to an absorbent article which includes the polysaccharide fibre ().

A method of producing a porous, liquid absorbent, open-cell polymeric foam material having properties which makes it suitable for use as an absorbent structure in absorbent articles such as diapers, pant diapers, sanitary napkins, incontinence guards, wound dressings, bed protections etc, comprising dissolving a polymer in a solvent, adding a surfactant and causing foaming, after which the polymer is crosslinked in the foamed mixture by means of a crosslinking agent. The temperature of the foam thus formed is lowered to a temperature below the freezing point of the solvent and the crosslinking reaction is continued during the freezing step, and after the main part of the solvent is removed from the formed foam material.

Method of producing an absorbent foam material

The invention refers to an absorbent structure in an absorbent article such as a diaper, a pant diaper, an incontinence guard, a sanitary napkin etc., the absorbent structure comprises an open-cell foam structure, the pore walls of said foam structure comprising a liquid-storing material having the capacity to store more than 7% synthetic urine defined according to the CRC method. The absorbent structure is characterized by that the pores of the foam structure contains hydrophilic fibers, at which at least the main part of the hydrophilic fibers are firmly anchored in the pore walls of the foam structure, and that the fiber amount is at least 10% by weight of the total weight of the open-cell foam in dry condition. The invention also refers to an absorbent article containing such an absorbent structure.
