IODINE- AND AMYLASE-CONTAINING FIBERS, PROCESS FOR PRODUCTION THEREOF, AND USE THEREOF

WIPO Patent Application WO/2010/146875

A1

Disclosed is a process for producing amylase-containing rayon fibers, which comprises a step of mixing an aqueous alkaline solution of an amylose with viscose to prepare a mixed solution, and a step of spinning the mixed solution to produce amylase-containing rayon fibers, and a step of bringing the amylase-containing rayon fibers into contact with iodine or a polyiodide ion to allow iodine or the polyiodide ion to be included in the amylase in the amylase-containing rayon fibers, wherein the amylose is an enzymatically synthesized amylase having a weight average molecular weight of 3 × 104 to 2 × 105 inclusive. Also disclosed is a method for collecting iodine from branckish water with high efficiency utilizing the amylase-containing rayon fibers.
