Abstract

A nonwoven fabric laminate possesses excellent elasticity, softness, water resistance, fuzz resistance and curl resistance, and has less stickiness.The nonwoven fabric laminate includes at least one meltblown nonwoven fabric layer and mixed-fiber spunbonded nonwoven fabric layers on both surfaces of the at least one meltblown nonwoven fabric layer, the mixed-fiber spunbonded nonwoven fabric layers each comprising mixed fibers including 10 to 90 wt % of continuous fibers of a thermoplastic elastomer (A) and 90 to 10 wt % of continuous fibers of a thermoplastic resin (B) other than the thermoplastic elastomer (A) ((A)+(B)=100 wt %).
