Title:

FIBER CAPABLE OF FORMING METAL CHELATE, PROCESS FOR PRODUCING THE SAME, METHOD OF TRAPPING METAL ION WITH THE FIBER, AND METAL CHELATE FIBER

Document Type and Number:

WIPO Patent Application WO/2000/052252

Kind Code:

A1

Abstract:

A fiber capable of forming a metal chelate which comprises a natural or regenerated fiber and, bonded to the molecules thereof through a crosslinking compound having a reactive double bond and a glycidyl group in the molecule, at least one metal-chelate-forming compound reactive with glycidyl which is selected from the group consisting of aminodicarboxylic acids, thiocarboxylic acids, and phosphoric acid; a process for producing the fiber; a method of trapping metal ions with the fiber; and a metal chelate fiber which effectively takes advantage of properties of the metal and can be easily discarded or incinerated.
