Bulky nonwoven fabric and method for producing the same

摘要

The object of the present invention is to provide a nonwoven fabric which is excellent in bulkiness and touch feeling as well as strength and dimensional stability and to provide a method for producing the above nonwoven fabric through a simple and convenient manner without employing any particular spinning device. The invention relates to a bulky nonwoven fabric composed of a stretched filament web which is prepared from either at least one layer of a stretched unidirectionally arranged filament web which is composed of almost unidirectionally arranged long fibers being stretched and shrunk or a stretched crosswise laminated filament web made of two or more layers of the stretched unidirectionally arranged filament webs and a short fiber web which is entangled with said stretched filament web and is crimped as a result of shrinkage of the long fibers, and a method for producing the same.
