Patent ID: 7837814

Claim:
A process for manufacturing a fine-fibers-dispersed nonwoven fabric comprising the steps of: ejecting bundled aggregates of fine fibers having a fiber diameter of 4 μm or less and a fiber length of 3 mm or less and made of an organic material prepared by removing a sea component from islands-in-sea type fibers, or a group of the aggregates, from a Venturi tube into a gas by an action of a compressed gas having a pressure of 2 kg/cm 2 or more and introduced from an inlet located upstream from and near the Venturi tube, and bringing the bundled aggregates of fine fibers or the group thereof, into collision with a flat region of a colliding means placed in front of an ejecting opening of the Venturi tube, to thereby divide the bundled aggregates or the group thereof into the fine fibers, and disperse the resulting fine fibers; collecting the dispersed fine fibers to form a fiber web; and bonding the fiber web to obtain the fine-fibers-dispersed nonwoven fabric.
