摘要： A method for manufacturing a molded product of the present disclosure includes a deposition step of depositing a mixture including a fiber and starch in air, a humidification step of applying water to the mixture, and a molding step of heating and pressurizing the mixture applied with water to obtain a molded product. The starch has a gelatinized and then pulverized particle diameter d50 of 0.30 mm or more and 1.0 mm or less, which is the average particle diameter of the finely pulverized product determined by a prescribed measuring method.

摘要： A method for producing a shaped article includes a deposition step, in which a mixture containing fibers and starch is deposited in the air; a moistening step, in which the mixture is supplied with water; and a shaping step, in which heat and pressure are applied to the mixture supplied with water to give a shaped article. The starch has a viscosity of 20 mPa·s or more and 200 mPa·s or less as a final viscosity at 50° C. of a 25% by mass aqueous suspension of the starch measured using a Rapid Visco Analyzer.

摘要： A waste paper recycling apparatus includes a liquid ejection device which receives a first liquid and a second liquid different from the first liquid; a receiving portion receiving a selection operation which selects one of the first liquid and the second liquid which is adhered to a predetermined region of a sheet containing fibers formed from waste paper; and a control portion which controls the liquid ejection device to adhere the liquid selected by the selection operation to the predetermined region. In the waste paper recycling apparatus, the first liquid contains a binder which binds fibers together, and the second liquid contains a pigment and a binder which binds fibers together.

摘要： A method for manufacturing a molded body, includes a deposition step of depositing a mixture containing fibers and a starch in air; a moisturizing step of applying water to the mixture; and a molding step of forming a molded body by heating and pressurizing the mixture to which the water is applied. In the method described above, the starch has a value of 100 or less, the value being represented by the following expression (I) and being obtained by measurement performed in accordance with the following measurement methods (1) to (4) using a rapid visco analyzer (RVA).
1,000−7×T−9×η (I)
In the expression (I), T represents a gelatinization peak temperature (° C.) of the starch, and h represents a setback viscosity (mPa·s) thereof, and the measurement is performed such that (1) after a water suspension containing the starch at 25 percent by mass is charged in the RVA as a measurement sample, the temperature thereof is increased to 50° C. and then maintained for one minute; (2) the temperature of the measurement sample is increased from 50° C. to 93° C. over 4 minutes and then maintained at 93° C. for 7 minutes; (3) the temperature of the measurement sample is decreased from 93° C. to 50° C. over 4 minutes and then maintained at 50° C. for 3 minutes; and (4) in the above (2) and (3), a rotational speed of a measurement paddle of the RVA is set to 960 rpm for 10 seconds after the start of the viscosity measurement and is then set to 160 rpm 10 seconds thereafter.-
