サイド（H2O2,APS,KPS…等）を用いるものがある。[Prior Art] Conventionally, antibacterial. As a method for producing a hydrophilic puff having antifungal properties, a puff base material is dipped in an aqueous solution of polyethylene glycol / dimethacrylate and heated to cause graft polymerization. Inorganic peroxide (H 2 O 2 , APS, KPS, etc.) are used.

イドを過剰に添加する必要がある。[Problems to be Solved by the Invention] The conventional techniques described above have the problems that a processing odor is generated during the production of the hydrophilic puff and that the antibacterial agent flows out, but this is due to the oxidation action of the inorganic peroxide. It is based. Further, since this inorganic peroxide is consumed by the oxidizing action, it is necessary to add an excessive amount of the inorganic peroxide when preparing the aqueous solution.

First, the polymerization treatment liquid is 0.1 to 3 parts by weight (preferably 1.5 parts by weight) of polyethylene glycol / dimethacrylate # 600 per 100 parts by weight of water, a water-soluble azo initiator (trade name v-50 manufactured by Wako Pure Chemical Industries, Note 1) (Reference) 0.001 to 1 part by weight (preferably 0.01 part by weight) is added and blended. Immerse the puff base material in this polymerization treatment liquid under reduced pressure, impregnate the puff base material with the polymerization treatment liquid, and then
Graft polymerization occurs by heating in a water bath at ℃ for 50 minutes. After the completion of the reaction, the hydrophilic puff is obtained by washing with water, removing the attached chemicals, and drying.

The obtained puff has the highest hydrophilicity, can withstand more than 20 soap washings, and does not fall over.
