  • Patent number: 9243128
    Abstract: A composite material of the invention is a mixture of cellulose microfibers having a carboxyl group content of 0.1 to 3 mmol/g and a moldable polymeric material selected from the group consisting of a biomass-derived polymer and a petroleum-derived polymer. The biomass-derived polymer is preferably polylactic acid or pulp. The cellulose microfibers are preferably present in an amount of 0.01% to 60% by mass. Another composite material of the invention is a mixture of cellulose composite microfibers and a moldable resin, the cellulose composite microfibers being obtained by adsorbing a surfactant onto cellulose microfibers having a carboxyl group content of 0.1 to 3 mmol/g.

  • Patent number: 8256412
    Abstract: A warming device of sheet form having (1) a heat generating sheet prepared by papermaking and containing an oxidizable metal, a moisture retaining agent, and a fibrous material and (2) an air permeable holder holding the heat generating sheet. The warming device has a thickness of 0.1 to 10 mm and a flexural strength of 0.01 to 0.3 N/cm. The sheet preferably has a thickness of 0.1 to 2.0 mm. The fibrous material preferably has a CSF of 600 ml or less.

  • Patent number: 7094744
    Abstract: A method of producing a sheet type laundry detergent which comprises continuously or discontinuously applying a doughy detergent composition that has been prepared so as to have a viscosity of 1,000 mPa·s to 50,000 mPa·s at a shear rate of 10 s?1 to 1,000 s?1 onto a flexible support of continuous length that is running continuously in a prescribed direction under a shear rate condition of 10 s?1 to 1,000 s?1 by an application to form a thin layer of the doughy detergent composition.

  • Patent number: 6881441
    Abstract: An intermittently laying method for intermittently forming laid layers (14) comprising a fluidized substance (13) laid thereon on a surface of a sheet-like member (12) moving in one direction, in the moving direction, the method comprising steps of: folding a part of the sheet-like member (12) corresponding to a non-laid portion (15) between adjacent laid portions inwardly towards a back surface side of the sheet-like member (12) on an upstream side of a coating head (16) for laying the fluidized substance (13) on the sheet-like member (12) thereby forming a continuous surface-to-be-laid (30) on a surface side; continuously supplying the fluidized substance (13) from the laying means to the surface-to-be-laid thereby forming the laid layer (14); bringing back the inwardly folded non-laid portion (15) so as to be flush with the surface-to-be-laid (30) on a downstream side of the coating head (16); and intermittently interposing the non-laid portion (15) between continuously laid adjacent laid layers (14).
