摘要： A hydrolytic sheet is obtained by impregnating a base paper sheet with an aqueous agent. The base paper sheet has a weight per unit area of 30 to 150 gsm and includes a water-soluble binder. The aqueous agent includes a cross-linking agent which cross-links with the water-soluble binder and cellulose nanofiber.

摘要： Household tissue paper is obtained by applying a ply process to two or more sheets of base paper. First embossments and second embossments, arranged around the first embossments, are formed on an entire surface of the household tissue paper, a shape of a protruding part of each of the second embossments differing from a shape of a protruding part of each of the first embossments. Hence, because a contact area with an object to be cleaned or the like can be increased, it is possible to enhance surface strength of the household tissue paper being embossed and to enhance wiping performance.

摘要： A method for producing a roll-type gas diffusion layer is disclosed. The method includes preparing a carbon paper from carbon fiber chops having a low modulus of 10 to 100 Gpa; impregnating the prepared carbon paper with a phenol resin, and then carbonizing the resin-impregnated carbon paper at 1,800 to 2,400° C.; forming a microporous polytetrafluoroethylene resin layer on one side of the carbonized carbon paper, to prepare a gas diffusion layer sheet; and winding the prepared gas diffusion layer sheet on a roll. Since the roll of gas diffusion layer is formed using the carbon fiber chops having a low modulus, the gas diffusion layer exhibits excellent and uniform spreading properties. Therefore, sealing between the gas diffusion layer and the fuel cell separation plate is reliably secured without using a separate binder.

摘要： A process for improving the dry strength of the paper by applying a dry-strength enhancing composition to pulp during a paper-making process, said dry-strength enhancing composition comprising a solution comprising an acid mixed with at least one metal ion wherein the metal ion is generally provided as a metal sulfate or a solubilized sulfate to form a mixture (I), wherein the mixture generates an exothermic reaction to form a mixture (II) and wherein the mixture is cooled to form the dry-strength enhancing composition.

摘要： The present invention provides for a method of producing a creped paper and the crepe paper products made using this method. The method includes treating the surface of a crepe fiber web and/or surface of a Yankee drum dryer or cylinder with compositions containing a combination of hydrophobes and surfactants and wherein these compositions have been subjected to physical treatments to reduce the mean particle size to about 1 micron (μm) or less.
