Patent number: 4744830Abstract: 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.Type: GrantFiled: November 26, 1986Date of Patent: May 17, 1988Assignee: Agency of Industrial Science & TechnologyInventors: Yoshinari Kobayashi, Ryukichi Matsuo
