Title:
NONWOVEN FABRIC HAVING LOW FIBER DENSITY
Document Type and Number:
WIPO Patent Application WO/2004/104285
Kind Code:
A1
Abstract:
Disclosed is a nonwoven fabric having a low fiber density, characterized in that a nonwoven fabric is sequentially drawn in a first axis and then in a second axis, thus increasing an open pore ratio and flexibility. That is, a biaxial drawing process of the nonwoven fabric can lead to an increased open pore ratio and flexibility of the nonwoven fabric. Thereby, nonwoven fabric articles having high qualities can be inexpensively provided.
