Iodine fiber with fast iodine absorbing and stabilizing effects and sterilization function, and preparation method and use method of iodine fiber

The invention belongs to the technical field of iodine fiber sterilization and iodine stabilization, and particularly relates to iodine fiber with fast iodine absorbing and stabilizing effects and a sterilization function, and a preparation method and a use method of the iodine fiber. The problems of poor stability, easy damage, easy generation of iodine secondary pollution and the like of the existing anion exchange resin adsorption or exchange of iodine or polyiodides are solved. The iodine fiber is prepared from iodine and ion exchange fiber, and is iodine-iron change fiber or polyiodides-ion exchange fiber. The preparation method comprises the following steps of performing pretreatment on the ion exchange fiber; testing the exchange volume of the ion exchange fiber after the pretreatment; taking a reaction with the simple substance of iodine or polyiodides ions or iodine ions and the simple substance of iodine for preparation. The use method is completed through a simple filtering tube device. In the use process, the iodine fiber has the advantages that the adsorption speed is high; the preparation method and the process are simple; the iodine fiber is suitable for mass production.
