Abstract
A method of manufacturing calcium alginate sheets, without the use of an adhesive binder, by use of a Fourdrinier paper making machine is disclosed. Alginate material in fibrous form is obtained by squirting an aqueous solution of water-soluble alginate via a spinneret into a bath of an inorganic salt, whose cation will react with the alginate to produce a water-insoluble alginate. This fibrous alginate material is then fed into a Fourdrinier machine and formed into a sheet, and the pH value of the fibrous alginate slurry at the screen wire of the machine is at or below 7.0.
