Document Type and Number:
WIPO Patent Application WO/2008/010307
Kind Code:
A1
Abstract:
A process for producing a fiber assembly requiring micropores, such as a battery
separator or any of various filters; in particular, a process for producing a
fiber assembly according to electrostatic spinning that excels in productivity,
being easy in maintenance. There is provided a process for producing a microfiber
assembly, comprising applying high voltage to bubbles (4) continuously generated
in polymer solution (3) or a polymer melt to thereby carry out electrostatic spinning.
The bubbles (4) can be those generated by passing compressed air (1) through porous
material (2), or minute canal, of a member or a combination of two or more members
selected from among plastic, ceramic and metal material.
