ABSTRACT:
Nonwoven structures, prepared from meltblown microfibers, and fibers having heterogeneous melt viscosity. The structures can be in the form of composite nonwoven fabrics, made from alternating layers of the indicated meltblown and heterogeneous fibers; the melt flow rate, of the surface of the heterogeneous fibers, can be one third or more of the meltblown fibers' melt flow rate. The composite nonwoven fabrics have excellent barrier properties, and are useful as sterilization wraps, and for other medical, industrial, and hygiene applications.
