Abstract
A material for distributing fluid can include a first side edge, a second side edge, a first end edge, and a second end edge. The material can include a first surface and a second surface opposite from the first surface. The material can be liquid impermeable and at least one of the first surface and the second surface include at least one channel. The channel can include a channel width, a channel length, and a channel depth. The channel width can be from 0.1 mm to 2.5 mm. The channel depth can be configured such that the channel does not extend completely through the material.
Claims20
A material comprising:
- a first side edge;
- a second side edge opposite from the first side edge;
- a first end edge;
- a second end edge opposite from the first end edge;
- a first surface;
- and
- a second surface opposite from the first surface, a distance between the first surface and the second surface as measured along a line that is perpendicular to a plane defined by a longitudinal axis and a lateral axis of the material defining a thickness of the material;
- wherein the material is liquid impermeable and at least one of the first surface and the second surface comprise at least one channel, the at least one channel comprising:
- a channel width, the channel width being from 0.5 mm to 2.5 mm;
- a channel length;
- a channel depth, the channel depth being configured such that the channel does not extend completely through the material, and wherein the channel depth is greater than the thickness of the material, wherein the channel depth is a greatest depth of the channel as measured along the line perpendicular to the plane defined by the longitudinal axis and the lateral axis of the material.
