COMPOSITE SHEETS FOR ABSORBENT MATERIALS

Abstract

The invention relates to a composite sheet for absorbent materials that exhibits superior durability while maintaining a pleasant feel against the skin.The composite sheet (10A) is a composite sheet (10A) for absorbent materials with the first (W), second (L), and thickness (T) orientations perpendicular to each other, consisting, in order, of the first nonwoven fabric (11) and the second nonwoven fabric (14) in the thickness (T) orientation, and also includes several thermal bonding (18) parts between the first nonwoven fabric (11) and the second nonwoven fabric (14) together, in which the first nonwoven fabric (11) has the first (12) and second (13) fiber layers arranged between the first (12) and second (14) fiber layers; the first fiber layer (12) consists of composite fibers; The composite fiber, in cross-section, consists of a polypropylene-based resin layer (20) and a polyethylene-based resin layer (22) consisting of a polyethylene-based resin; a second fiber layer (13) consisting of monofilaments made from polypropylene-based resin; and a second nonwoven fabric (14) containing polypropylene-based resin on the surface of the side in contact with the second fiber layer (13).
