Title:
NONWOVEN FABRIC AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2009074196
Kind Code:
A
Abstract:
To provide a bulky nonwoven fabric having excellent heat and chemical resistances and to provide a method for producing the bulky nonwoven fabric.
The nonwoven fabric is formed from filaments having a melting liquid crystal-forming wholly aromatic polyester having a melt viscosity of 20 Pa s or less at 310C or above as a main component and having an average fiber diameter of 1-15 m, and the principal plane has a plurality of peak parts 1. The apparent density of the nonwoven fabric is 0.01-0.3 g/cm. The ratio (Sm)/(Ym) of the average interval (Sm) of the apexes of the adjacent peak parts to the average height (Ym) of the plurality of peak parts may be about 0.02-100.
