Title:
NONWOVEN FABRIC AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2012077388
Kind Code:
A
Abstract:
To provide a cellulosic nonwoven fabric that is excellent in mechanical properties, stiffness under high temperature, and a water absorbing property.
A method for producing a cellulosic nonwoven fabric comprises: forming a web of fibers obtained by melt spinning a resin composition including a thermoplastic cellulose ester as a main component; bonding the web thermally by heat embossing rolls to obtain a sheet-like material; and subjecting the obtained sheet-like material to an alkali saponification. The fibers are fixed and integrated with each other without interposing a binder. The cellulosic nonwoven fabric has a tensile strength in the longitudinal direction of 1.0 (N/5 cm)/(g/m2) or more.
