Abstract
Provided are a sub-micron fibrous membrane in which sub-micron fibers aligned along one axis and sub-micron fibers in a random pattern form a network, and a method for producing the sub-micron fibrous membrane.
Claims20
A sub-micron fibrous membrane comprising:
- a plurality of first sub-micron fibers spun in alignment along one axis;
- and
- a plurality of second sub-micron fibers spun in a random pattern to form a network with the plurality of first sub-micron fibers.
A method for producing a sub-micron fibrous membrane, the method comprising:
- forming a plurality of first sub-micron fibers aligned along one axis by continuously electrospinning a polymer solution through a plurality of first electrospinning portions:
- forming a plurality of second sub-micron fibers in a random pattern by continuously electrospinning the polymer solution through a plurality of second electrospinning portions;
- and
- coating a carrier with a network of the plurality of first sub-micron fibers and the plurality of second sub-micron fibers by continuously passing the carrier through an area where the plurality of first sub-micron fibers and the plurality of second sub-micron fibers are formed, while the first electrospinning portions and the second electrospinning portions are continuously electrospinning the polymer solution.
