The invention relates to highly effective disinfecting or sterilising cloths with chlorine dioxide as the main active ingredient. For this, the chlorine dioxide is only generated shortly before use by bringing a cloth impregnated with a chlorite or chlorate salt in contact with a clearly defined amount of a suitable activation agent that is fluid or dissolved or admixed in a fluid, and prepackaged as a single dose, for the generation of chlorine dioxide. In a preferred embodiment, the impregnated cloth and the activation fluid are packaged in a common packaging unit and the activation occurs by breaking through a barrier separating the cloth or the cloths and the activation fluid. In a further preferred embodiment, the packaging is a moulded part having two packaging spaces separated from one another by removable barriers, which can be converted into a moulded part with only one chamber via simple pressure in one direction. The activation fluid or the disinfecting cloth can contain further substances, such as the pH-value-controlling substances, surfactants, guanidine derivatives, aldehydes, phenoxyethanols, phosphate esters, alcohols, sulfoxides, etc. Preferably, the disinfecting cloth according to the invention is used for disinfecting and/or sterilising medical instruments and/or medical products and/or surfaces.

To provide an antibacterial and water-disintegrable toilet paper.

A toilet paper includes three or four sheet layers. Each sheet has a basis weight of 12.0 to 16.0 g/m.sup.2.

Each sheet has a paper thickness of 80 to 140 μm. At least one pair of adjacent sheets are bonded to each other at a large number of bonding points with an adhesive 10. The adhesive 10 is polyvinyl alcohol, and contains benzalkonium chloride.

Disclosed is a method for controlling a biofilm, for removing a formed biofilm and/or for controlling a growth of microorganisms, preferably bacteria, in an aqueous environment of an industrial manufacturing process including cellulosic fibre material. In the method, a composition including a compound selected from a group consisting of 3-[(4-methylphenyl)sulphonyl]-2-propenenitrile and 4-amino-N-2-thiazolyl-benzenesulphonamide is administered to the aqueous environment of the process.

A wipe has a substrate, a treatment solution impregnated into the substrate, the treatment solution including an antifungal agent, an antifungal agent solvent, and a carrier fluid, wherein the treatment solution is essentially free of alcohol. A treatment solution, has an antifungal agent, an antifungal agent solvent, and a carrier fluid, wherein the treatment solution has an alcohol content of 6 wt % or below of the total solution.

The invention relates to a cellulosic fibre loaded with a biologically active substance formed by the steps of: a) producing a cellulosic fibre loaded with ion exchanger, b) after-treating the fibre thus produced with an aqueous solution of a metal salt which exhibits antibacterial activity and/or antiviral activity, and c) after-treating the loaded fibre with an aqueous fixing solution to convert the metal salt into a water-insoluble form. The cellulosic fibres thus produced can be used to form textile fabrics, wound dressings, sanitary products, specialty papers, packaging or filter materials.

A ply fibrous product comprises at least one ply selected from a nonwoven ply and a tissue paper ply, wherein the at least one ply selected from a nonwoven ply and a tissue paper ply comprises cellulosic fibers comprising an organic polycarboxylic acid and wherein the organic polycarboxylic acid has at least one carboxyl group covalently bound to the cellulosic fibers and at least one free carboxyl group. Due to the presence of covalent chemical bonds between a carboxyl group of the polycarboxylic acid and hydroxy groups of the cellulosic fibers present in all substrates, the ply fibrous products display a long-lasting acidic pH even after having been rinsed with water. In some embodiments a long-lasting acidic pH may be achieved in the nonwovens treated with an organic polycarboxylic acid even after washing with a washing detergent.

A method includes forming an aqueous fibre suspension including cellulosic fibres from one or more raw material flows, and applying at least one chemical and/or physical control measure to the aqueous fibre suspension or at least one of its raw material flows for control of microbial activity in the aqueous fibre suspension or the raw material flow before an inlet of an intermediate residence entity. In this manner a starting ORP value for the aqueous fibre suspension is obtained. The aqueous fibre suspension is in the intermediate residence entity at least a minimum delay time. A final ORP value is measured for the aqueous fibre suspension after an outlet of the intermediate residence entity before the formation of the fibrous web. An ORP difference value between the starting ORP and final ORP values is calculated. Finally, the aqueous fibre suspension is formed into a fibrous web and dried.
