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.

Composite material

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.

Warming tool in a sheet form

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&#xb7;s to 50,000 mPa&#xb7;s at a shear rate of 10 sto 1,000 sonto a flexible support of continuous length that is running continuously in a prescribed direction under a shear rate condition of 10 sto 1,000 sby an application to form a thin layer of the doughy detergent composition.

Method for producing sheetlike detergent

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