Abstract
The instant disclosure relates to an integral porous fiber media with distinguishable distribution of fiber density, fiber diameter and capillary force. The instant disclosure further relates to a fiber porous media that includes multiple density portions. The disclosed media is a single piece, such that the different density portions are not separable. The disclosed media provides improved liquid delivery properties for a specific liquid delivery device.
