摘要： The invention relates to a method for reducing bacterial endospores in an aqueous fibre suspension comprising recycled cellulosic fibres, wherein the fibre suspension has an original endospore amount, preferably of ≥10 000 CFU/ml. The method comprises adjusting the pH of the fibre suspension to a pH value of ≤6.5, adjusting the oxidation-reduction potential (ORP) of the fibre suspension to an ORP value of ≥200 mV with a first oxidizing agent, and introducing an amount of performic acid as a second oxidizing agent to the fibre suspension for reducing the bacterial endospores to an endospore amount of ≤1000 CFU/ml.

摘要： The present invention relates to a method for manufacturing an eco-friendly antibacterial polymer-coated paper in which an antibacterial coating agent is coated without releasing harmful substances to humans on the surface of a paper to ensure antibacterial activity and is easy to separate from the paper to enable their recycling. The method includes mixing 40 to 50% by weight of a mixture of methyl methacrylate and butyl acrylate, 0.5 to 3.0% by weight of a copper nanopowder, 0.5 to 2.0% by weight of an initiator, 1 to 5% by weight of a polymeric dispersant, and a balance of water to prepare a mixed solution, stirring the mixed solution at 70 to 80° C. for 5 to 10 hours for polymerizing the mixture to prepare a polymeric coating agent, and coating the polymeric coating agent to a thickness of 5 to 10 μm on a paper.

摘要： The present invention relates to specialty pulp products produced using bifunctional reagents composed of polymeric chain and end caps. The polymeric chain is preferably a polyalkylene glycol based polymer and the end caps are preferably a cationic quaternary ammonium. The bifunctional reagents are especially useful in making specialty fluff with dual functional properties—easy defiberization and antimicrobial properties. The specialty fluff of the present invention prevents odor by inhibiting bacteria growth and production of organic matters, especially when used in an absorbent article intended for body waste management such as baby diapers and adult incontinence device.

摘要： Self-cleaning banknotes are provided using coatings, inks and additives which are photo-active and catalytic to reactions which are effective in breaking up organic contaminants or dirt to allow for the self-cleaning of banknotes by ambient light exposure as well as the cleaning of processed banknotes using equipment with more intense optical excitation, thus increasing their usable life. The invention is usable with all substrates and particularly polymeric substrates such as biaxially-oriented polypropylene (BOPP). The invention further discloses a system which allows a certain class of fitness parameters to cause these banknotes to be redirected to a cleaning module, be revaluated, and then either returned to circulation or rejected and/or destroyed. In addition, inks which are photo-catalytic can be used for extending the life of the banknotes in printed regions.

摘要： A disposable paper towel with an anti-microbial lotion and is provided with a chromatic transfer indicator which undergoes a delayed, visually perceptible color change at a predetermined time after the towel is wetted. An anti-microbial lotion on the towel increases water absorbency times (WAR) to further promote lotion transfer to the skin and increase lotion transfer effectiveness.

摘要： Disclosed is an emulsion of an internal paper size and a biocidal emulsifying agent, such as a cationic non-starchy quaternary ammonium compounds, that is introduced into a paper-making furnish to produce an anti-microbial paper. The antimicrobial paper is useful as facing for gypsum panels. A method of making the paper includes emulsifying the internal size with a biocide before introducing the size to the paper furnish. A method of making a microbial growth resistant gypsum panel that incorporates the antimicrobial paper is also disclosed.

摘要： Methods to preserve starch present in pulp are provided and also methods to control calcium precipitation and/or scaling in digesters or BOD systems. The methods can be performed as part of a papermaking process. Process water containing pulp can be treated with a chloramine. Process water containing pulp with native starch can receive a double treatment with at least one biocide, such as chloramine, and at least one oxidant, such as sodium hypochlorite. The treatment can be performed in any suitable manner. The treatment can be performed at one or more stages or locations in a papermaking system. A target residual chloramine value or range can be achieved by the treatment. Packaging sheets/boards and other paper products manufactured using the methods provided exhibit superior strength and other desirable characteristics.
