摘要：
The fabrics of this invention have a unique combination of liquid barrier properties and high air permeability and comprise at least one carded nonwoven web comprising at least 10% by weight, based on the total weight of cardable fibers, of cardable polyolefin fibers having a fiber fineness of about 0.5 to about 1.2 decitex. Preferably the polyolefin fibers are hydrophobic polyolefin fibers, and the nonwoven material is thermally bonded. Laminates comprising at least one layer of the fabrics of this invention and at least one layer of another nonwoven material have the same unique combination of properties.
