摘要：There is provided a nonwoven fabric comprising a layer of a nonwoven web comprising filaments prepared from a thermoplastic polymer. The thermoplastic polymer is a blend of at least one isotactic polymer having an isotacticity of at least 85, up to 40 weight percent of at least one atactic polymer having a isotacticity of less then 20, and the blend may also have a fluorocarbon in a amount between about 0.1 and 3.0 weight percent. The fabric may be produced by the spunbonding and meltblowing processes and has good strength, barrier and softness.
