Document Type and Number:
Japanese Patent JP2023051889
Kind Code:
A
Abstract:
To provide a laminated nonwoven fabric having adequate friction force and a manufacturing method thereof.SOLUTION: A laminated nonwoven fabric has a first fiber layer, a second fiber layer, and an intermediate fiber layer disposed between the first fiber layer and the second fiber layer. The first fiber layer contains 10 mass% or more and 90 mass% or less of water-repellent cellulose fiber and 10 mass% or more and 90 mass% or less of hydrophilic cellulose fiber based on the total mass of the first fiber layer. The second fiber layer contains 10 mass% or more and 90 mass% or less of water-repellent cellulose fiber and 10 mass% or more and 90 mass% or less of hydrophilic cellulose fiber based on the total mass of the second fiber layer. The intermediate fiber layer contains 70 mass% or more of hydrophilic cellulose fiber based on the total mass of the intermediate fiber layer. The first fiber layer, the intermediate fiber layer, and the second fiber layer are integrated by entanglement of fibers with each other.SELECTED DRAWING: None
