    摘要： 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.

    摘要： A non-woven alginate fabric useful as a wound dressing is made by spreading a tow of calcium alginate filaments in a flow of water, overfeeding the spread filaments onto a water-pervious support so that the filaments cross over each other and drying the filaments so that the alginate filaments become bonded to each other at their points of contact where they cross over each other. The filaments used have preferably been stretched in an atmosphere of steam and water-washed but not dried and are preferably dried by suction on the water-pervious support.

    摘要： A process is provided for manufacturing a smokeable material including a basic material consisting of calcium alginate in fibrous form into which filler material is incorporated. The calcium alginate fibers are formed from the admixture of two solutions, the filler material being suspended in at least one of the solutions in such quantity and the solutions being so mixed that the filler is incorporated integrally in the fibres as they are formed so as to constitute more than 10% of the fibres by weight.

    摘要： The invention provides a fibrous binder capable of exhibiting a bonding ability in a dry condition for fibers having no self-adhesiveness in paper making but capable of imparting the paper made by use of the same with disintegrability into discrete fibers in a wet condition so that the paper is disposable in water. The fibrous binder is prepared by wet-spinning of an aqueous dope containing a water-soluble salt, e.g. sodium salt, of alginic acid and an alkyleneglycol ester of alginic acid in a specified proportion into a coagulation bath containing a water-soluble salt of certain metals, e.g. calcium, of which the ions are replaceable with the sodium ions of the water-soluble salt of alginic acid to convert the acid into a water-insoluble salt so as to form a water-insoluble gel in a fibrous form of a blend composed of the water-insoluble metal salt of alginic acid and the alkyleneglycol ester of alginic acid.
