Disclosed is a method for manufacturing an eco-friendly antibacterial coated paper. According to the method, an antibacterial coating agent is coated without releasing harmful substances to humans on the surface of a paper to ensure antibacterial activity. The antibacterial coating agent and the paper are easy to separate from each other to enable their recycling. The method enables the manufacture of a coated paper that has high antibacterial activity and waterproofness and is thus useful for surface coating of food. The method releases no volatile organic compounds. The coating components of the coated paper are not dissolved in water upon contact with water during use, causing no environmental problems and no harm to human health. In addition, the coating layer and the paper can be easily separated from each other after use, enabling the recycling of the paper.

A method for manufacturing a fibrous web, such as web of paper, board, tissue or the like is disclosed. The method includes obtaining at least one fibre suspension of lignocellulosic and/or cellulosic fibres and feeding the fibre suspension into an intermediate residence entity. The fibre suspension including bacterial endospores, is discharged out of the intermediate residence entity via an outlet after a residence time of at least 2 hours in the intermediate residence entity and after a time delay the fibre suspension is formed into a fibrous web. Bacterial endospores are sensitized by adding a germinant surfactant including a primary or secondary ammonium head group and a linear unsubstituted C12-alkyl tail, to the fibre suspension at an addition point located at a lower part of the intermediate residence entity or after the outlet of the intermediate residence entity, but before the formation of the fibrous web.

A composition is contained a blend zone prior to refining containing non-fibrillated virgin cellulose fibers, waste/recycle cellulose fibers or both; cellulose ester fibers, water, and one or more additives comprising fillers, internal sizing agents, biocides, process anti-foaming agents, colorants, optical modifiers, or a combination thereof. An in-line mixer can be used for adding the additives, and the consistency of the composition is lowered relative to a feed of material from a hydropulper.

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.
