摘要:
A nonwoven fabric laminate, comprising an elastic nonwoven fabric and a stretch spunbond nonwoven fabric having a rate of elongation with maximum load of 50% or more that is positioned on at least one side of the elastic nonwoven fabric, and satisfying following (1) and (2): (1) the elastic nonwoven fabric is formed from a resin composition comprising a specific low crystallinity polypropylene and an afpha-olefin copolymer A, and the alpha-olefin copolymer A comprises a structural unit derived from ethylene and a structural unit derived from propylene, has a melting point of 100°C or more, and has a degree of crystallinity of 15% or less. (2) the resin composition comprises alpha-olefin copolymer A in an amount of from 5 parts by mass to 50 parts by mass with respect to 100 parts by mass of the resin composition.本發明是一種不織布積層體,其包括彈性不織布、及配置於所述彈性不織布的至少單面側且至少一方向的最大負荷伸長率為50%以上的伸長性紡黏不織布,且滿足下述(1)及(2)。(1)所述彈性不織布包含含有特定的低結晶性聚丙烯、及α烯烴共聚物A的樹脂組成物,所述α烯烴共聚物A包含源自乙烯的結構單元及源自丙烯的結構單元且熔點為100℃以上、結晶度為15%以下。(2)所述樹脂組成物相對於所述樹脂組成物100質量份而含有α烯烴共聚物A 5質量份~50質量份。
