摘要： The invention provides methods for the preparation of nonwoven spunbonded fabrics and various materials prepared using such spunbonded fabrics. The method generally comprises extruding multicomponent fibers having an islands in the sea configuration such that upon removal of the sea component, the island components remain as micro- and nanofibers. The method further comprises mechanically entangling the multicomponent fibers to provide a nonwoven spunbonded fabric exhibiting superior strength and durability without the need for thermal bonding.
