(57) [Summary] (Modified) [Purpose] A new type that has excellent elasticity, that is, excellent stretchability in a two-dimensional state, and also excellent fit to curved and stretched parts. Provided are a meltblown nonwoven fabric and various laminated materials using the meltblown nonwoven fabric. A meltblown nonwoven fabric 1 is prepared from the ethylene-α-olefin copolymer having a density of less than 0.900 g / cm 3 and a crystallinity of 5 to 40% or a resin composition mainly composed of the copolymer by a meltblown method. Then, a meltblown nonwoven fabric obtained by a meltblown method from the copolymer or a resin composition containing the copolymer as a main component and a dry process nonwoven fabric are laminated and integrated to obtain nonwoven fabric laminates 2, 2a, 2b, Further, a melt-blown nonwoven fabric 2, 2a, 2b from the above-mentioned copolymer or a resin composition containing the copolymer as a main component, a dry-laid nonwoven fabric laminated on the melt-blown nonwoven fabric, and a dry-laid nonwoven fabric A poultice is obtained from the drug layer. |
