(57) [Problem] To provide a nonwoven fabric structure which is bulky, has good water absorption, and has high strength even when wet. SOLUTION: The pulp fiber (A) and the heat-adhesive composite short fiber (B) are mixed, and the heat-adhesive composite short fibers (B) and / or the pulp fiber (A) and the heat-adhesive composite are mixed. A nonwoven fabric structure in which at least two layers of a nonwoven fabric substantially bonded to a short fiber (B) are laminated, and in the two-layer nonwoven fabric, the mixing ratio of (A) and (B) is different from each other. And the mixing ratio of (B) in one of the nonwoven fabrics is 40 to 90% by weight based on the weight of the nonwoven fabric, and 5 to 60% of the surface area of the nonwoven fabric located in the outermost layer. Are thermocompression bonded. |
