| description | PROBLEM TO BE SOLVED: To provide a composite membrane having an ability to remove ultra low concentration ions, high water permeability, and a long life, and to provide a method for producing the same.SOLUTION: An ion exchange element 20 comprises a core material 10, flow passage material sheets 9 and laminated sheets which are wound on the outer periphery of the core material 10. The laminated sheet is prepared by intervening an ion exchange film 3 between ion exchange fiber nonwoven fabrics 4, 4 held on holding sheets 4s. The laminated sheets are passed through heating rollers 1, 2 to press the nonwoven fabrics 4 to the film 3, and the holding sheets 4s are then peeled. An embossing processing may be applied. |
