Article Formed Into Sheet, Method for Producing the Same and Exothermic Formed Article

A molded article comprising a powder and a fibrous material obtained by a wet papermaking process,

• the fibrous material having a fiber length frequency distribution characterized in that 30% to 90% of the fibrous material has a fiber length of 0.4 to 2.0 mm and 9% to 50% of the fibrous material has a fiber length of 0.4 mm or less, and
• the molded article containing at least 50% by weight of the powder.

A method of producing a molded article by a wet papermaking process using a slurry composition prepared by adding a cationic flocculant and an anionic flocculant to a slurry system containing a powder, a fibrous material, and water,

• said method comprising first adding one of the cationic flocculant and the anionic flocculant to the slurry system to make the slurry system bear an excessive amount of charge and then adding the other flocculant to the slurry system to put the charges of the slurry system into a neutralized state.

A method of producing a molded article by a wet papermaking process using a slurry composition containing a powder, a fibrous material, water, a cationic flocculant, and an anionic flocculent,

• wherein the anionic flocculant is a carboxymethyl cellulose salt having a degree of etherification of 0.6 to 1.5 and a 1% viscosity of 100 to 4000 MPa·s.
