US 2022/0104972 A1 · METHOD FOR PRODUCING ABSORBENT ARTICLE

Abstract

[Object] To provide a method for producing an absorbent article comprising a fiber assembly layer of a cellulose acetate fiber, which can sufficiently apply a drug to the cellulose acetate fiber. [Solution] A method for producing an absorbent article, wherein the absorbent article comprises: a fiber assembly layer including a cellulose acetate fiber, and a member including a water absorbent fiber and directly disposed on the fiber assembly layer, and the method comprises: a first step of opening a cellulose acetate tow and collecting a cellulose acetate fiber to form a fiber assembly layer, a second step of spreading a fiber solvent on the fiber assembly layer and drying the fiber assembly layer; a third step of spreading a drug aqueous solution containing an antibacterial agent and/or a deodorizer on the surface where the fiber solvent has been spread of the fiber assembly layer; and a fourth step of mounting the member on the surface where the drug aqueous solution has been spread of the fiber assembly layer.
