Document Type and Number:
Japanese Patent JP2005509546
Kind Code:
A
Abstract:
The present invention is directed to a nonwoven compound fabric comprising one or more layers of nano-denier continuous filaments and at least one layer of a strong and durable substrate, wherein said nonwoven compound fabric has an improved barrier performance as measured by the hydrostatic head to barrier layer basis weight ratio. In the present invention, one or more strong and durable substrate layers are formed, each layer comprising continuous thermoplastic filament spunbond. A barrier layer preferentially comprising nano-fibers of infinite length, wherein the average fiber diameter of the nano-fiber is in the range of less than or equal to 1000 nanometers, and preferably less than or equal to 500 nanometers, is applied to at least one substrate layer.
