Title: METHOD FOR PRODUCING ABSORBENT ARTICLE
Abstract:
The present invention provides a method for producing an absorbent article in which the flexibility and the cushioning properties of a surface sheet can be improved through bulkiness recovery, and the entry of fibers into holes in the surface sheet can be prevented to maintain the absorption performance. The method for producing an absorbent article includes: a bulkiness recovery step in which a first sheet, serving as the surface sheet, is heat-treated to recover the bulkiness thereof; a punching step in which, in the first sheet (P10) that has undergone the bulkiness recovery, a plurality of holes are formed in the first sheet by punching the first sheet from one side of the first sheet to the other side of the first sheet with a plurality of punches for punching; and a laminating step in which a laminate body, in which the first sheet, an absorbent body (P1), and a sheet (BS) serving as a back sheet are laminated, is formed.
