发明名称 METHOD FOR MAKING AN ABSORBENT ELEMENT FOR DISPOSABLE ABSORBENT ARTICLES HAVING AN INTEGRATED ACQUISITION LAYER
摘要 The present invention relates to a method for making a layered absorbent element, for use in disposable absorbent articles, which comprises a top layer and a bottom layer. The method includes providing a fibrous nonwoven layer having a basis weight from about 20 gsm to about 100 gsm, and a thickness of from about 0.25 mm to about 5 mm, providing an air laid or a wet laid manufacturing line comprising a forming screen, placing said nonwoven layer onto said forming screen, forming onto the nonwoven layer an air laid or wet laid layer comprising fibers and superabsorbent polymers by depositing these materials onto the nonwoven layer using an air laid or wet laid process where the nonwoven layer acts as forming screen. The resulting material is then compressed.

主权项 1. A method for making a layered absorbent element for use in disposable absorbent articles, said layered absorbent element comprising a top layer having an acquisition function and a bottom layer having a storage function, said method comprising the steps of: a. providing a fibrous nonwoven layer having a basis weight from about 20 gsm to about 100 gsm, and a thickness of from about 0.25 mm to about 5 mm; b. providing an air laid or a wet laid manufacturing line comprising a forming screen; c. placing said nonwoven layer onto said forming screen; d. forming onto said nonwoven layer an air laid or wet laid layer comprising fibers and superabsorbent particles by depositing said fibers and superabsorbent particles onto said nonwoven layer to define a layered absorbent element material; and e. compressing said layered absorbent element material.
