Abstract:
1. An elastic nonwoven fabric consisting of one layer wherein a long elastomeric fiber and a long nonelastomeric fiber are uniformly mixed together by spinning with a melt-blowing method that uses a spinneret having both a spinning hole for discharging elastomeric resin and another spinning hole for discharging nonelastomeric resin thereon, wherein a ratio of said long elastomeric fiber to said long nonelastomeric fiber ranges from 50/50 to 95/5 on a weight basis, said long elastomeric fiber has an average diameter (Bd) of 5 to 40 μm, an elongation recovery rate of the elastic nonwoven fabric after 50% elongation is 70% or higher, a separation resistance of two sheets of the same is equal or less than the strength at 50% elongation, and a ratio of Bd to an average diameter (Ad) of said long nonelastomeric fiber is no less than 2.
