Abstract
A method for producing a shaped article includes a second web forming step, in which a mixture containing fibers and a binding material is deposited in the air, the binding material containing starch and an alkali metal salt; a moistening step, in which the mixture is supplied with water; and a sheet-forming step, in which heat and pressure are applied to the mixture supplied with water to give a sheet. The alkali metal salt content of the binding material is 2.0% by mass or less of the total mass of the starch.
Claims10
A method for producing a shaped article, the method comprising:
- a deposition step, in which a mixture containing fibers and a binding material is deposited in air, the binding material containing starch and an alkali metal salt;
- 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 the water to give a shaped article, wherein:
- an alkali metal salt content of the binding material is 2.0% by mass or less of a total mass of the starch.
A binder for dry shaping, the binder comprising a binding material that contains an alkali metal salt and a starch that joins fibers together when supplied with water, wherein:
- an alkali metal salt content of the binding material is 2.0% by mass or less of a total mass of the starch.
