However, it lacks washing durability, and is used for futon cotton, wall paper, etc., but is unsuitable for items that require washing resistance.

At present, a deodorizing fiber structure that has good washing durability and can maintain its deodorizing effect for a long period of time has not yet been completed.

(Problems to be Solved by the Invention) An object of the present invention is to provide a fiber structure that has excellent washing durability and has a deodorizing effect for a long period of time.

This is related to durable deodorizing fiber structures made by imparting oii%, and the washing durability, which has not been solved with conventional methods, has been improved.
Moreover, the deodorizing effect can be maintained for a long period of time.
