    Abstract: PURPOSE:To maintain the performance of a sheet-like material made of fiber in a state of electret even when used in a watery place, by laminating a sheet- like materials made of ion-exchange fiber with a sheet-like material made of fiber in a state of electret or a sheet-like material made of glass fiber. CONSTITUTION:A sheet-like material is obtained using an ion-exchange fiber having the degree of water content of 0.1-10. Weight per unit area of the sheet-like material is more than 30g/m . A sheet-like material in a state of electret is obtained after a high-molecular substance which is capable of change to electret is formed into fiber or into films. And glass micro-wool composed of fine glass wool is formed into pulp which is capable of making paper so as to be formed into a sheet. The sheet-like material made of ion-exchange fiber, the sheet-like material of fiber in a state of electret or the sheet-like material of glass wool are laminated. When they are laminated, the sheet-like material of fiber in a state of electret can be formed into a sandwich form.

    Abstract: PURPOSE:To provide a water purifying apparatus capable of absorbing and removing a harmful component in drinking water, a malodorous component and fungi, and obtaining taste water for a long period. CONSTITUTION:The water purifying apparatus has an ion-exchange body as a water purifying component, and the ion type of the exchange group of the ion-exchange body is a mixture form of one or more kinds selected from Fe, Ca Mg, Ag, K, Ni and Co.

    Abstract: PURPOSE:To obtain inexpensively and easily a practical, highly pure ion exchanger by performing the crosslinking and sulfonation reaction of a fibrous molding having an aromatic ring at a low temperature or for a short time. CONSTITUTION:A process for reacting a fibrous molding essentially consisting of an aromatic polymer in concentrated sulfuric acid containing a formaldehyde source to introduce simultaneously crosslinking groups and at least 0.05mol, per mol of the aromatic rings of the polymer, sulfonic acid groups into the molding, wherein 0.001-0.5wt.%, based on the reaction solution, at least one element selected from among Ag, Ni and Fe is added to the reaction solution.
