The iodine compound solution used in the present invention is not particularly limited, and potassium iodide (a mixture of iodine and potassium iodide) or sodium iodide (a mixture of iodine and sodium iodide) is dissolved in a solvent such as water or alcohol. Or a mixture obtained by adding any of nonylphenoxypolyethylene glycol, polyethylene glycol polypropylene glycol block polymer, and polyvinylpyrrolidone thereto. The iodine concentration of the solution is not particularly limited, but is usually selected from the range of 0.01 to 20% by weight.
Preferably, the concentration is 0.1 to 10% by weight, and when the concentration is less than 0.01% by weight, the bactericidal property is inferior.
If it exceeds, the amount of iodine scattered in the air increases, which is uneconomical, which is not preferable. Potassium iodide or sodium iodide to be added is 5 to 20 times the amount of iodine (weight conversion)
It is preferable to put in.

The above-mentioned treatment may be performed after the above-mentioned fabric is formed, and the latter method may be suitably employed. In the above treatment, a coating method or a dipping method is adopted. In the coating method, the above-mentioned iodine compound solution is coated by a method such as a coater method or a spray method.
