Abstract
A non-woven fabric laminate that is excellent in strechability, flexibility, and bulkiness, and that is less sticky and is suitable for a mechanical fastening female material. The non-woven fabric laminate includes a mixed fiber spunbonded non-woven fabric and a non-woven fabric comprising a crimped fiber that is laminated on at least one face of the mixed fiber spunbonded non-woven fabric, which includes a continuous fiber of a thermoplastic elastomer (A) in the range of 10 to 90% by weight and a continuous fiber of a thermoplastic resin (B) in the range of 90 to 10% by weight (where (A)+(B)=100% by weight). The non-woven fabric laminate can be suitably used for a sanitary material and other materials. More specifically, there can be mentioned for instance an absorbent article such as a disposable diaper and a menstrual sanitary product as a sanitary material.
