发明名称 Elastomeric nonwovens
摘要 A nonwoven fabric and disposable articles comprising the same are provided. The nonwoven fabric can include one or more facing layers thermally bonded to one or more inner layers. The facing layers are inelastic or partially elastic nonwoven webs comprising one or more propylene-based polymers. The facing layer has a permanent set above 30%. The inner layers are elastic nonwoven webs comprising one or more propylene-based polymers and one or more slip agents. The inner layer has a permanent set below 28%, and the one or more propylene-based polymers have (i) 60 wt % or more units derived from propylene, (ii) isotactically arranged propylene derived sequences, and (iii) a heat of fusion less than 45 J/g.
