Claims10
A method for producing fibers with corrugations, the method comprising:
- flowing a first fluid through a first channel at least partially defined in a spinneret;
- rotating a projection of the spinneret that extends into the first channel of the spinneret as the first fluid flows past the projection;
- and
- solidifying the first fluid to form a fiber downstream of the projection;
- wherein rotating the projection comprises rotating the projection in a first direction and rotating the projection in a second direction opposite the first direction.
