AI Technical Summary
Technical Problem
Existing absorbent articles face issues with sweat transfer and diffusion due to adhesive or heat-sealed joints between layers with different sweat-absorbing properties, leading to hindered sweat diffusion and potential skin problems.
Method used
A laminated nonwoven fabric with a hydrophilic gradient, where the first layer has lower hydrophilicity than the second layer, and fibers are intertwined without adhesion, allowing for efficient sweat draw-in and diffusion.
Benefits of technology
The laminated nonwoven fabric enhances sweat transfer and diffusion, reducing skin problems like eczema and heat rash by promoting quick sweat movement from the skin side to the non-skin side.

Abstract
To provide a laminated nonwoven fabric with excellent fluid absorption and diffusion properties. [Solution] A laminated nonwoven fabric (100) for absorbent articles comprises a first layer (101) having first fibers (101a) and a second layer (102) having second fibers (102a), wherein the first layer (101) is located on the skin side of the laminated nonwoven fabric (100), and the second layer (102) is located on the non-skin side of the laminated nonwoven fabric (100), the hydrophilicity of the first fibers (101a) is lower than that of the second fibers (102a), and at least a portion of the first fibers (101a) and at least a portion of the second fibers (102a) are intertwined with each other.
