Abstract
A fiber is disclosed having a central axis or spline and a major outer surface, the fiber made of a base material and poly(vinylidene fluoride), the proportion of base material to poly(vinylidene fluoride) being greater towards the central axis or spline of the fiber than at the major outer surface of the fiber. The base material may be selected from the group consisting of polyethylene, polypropylene and nylon. The fiber has a surface roughness.
Claims24
A fiber having a central spline and a major outer surface, comprised of a base material and a polymer wherein the proportion of base material to the polymer is greater towards the central axis of the fiber than at the major outer surface of the fiber.
A fiber, comprising:
- an elongated body comprised of at least a base material and a poly vinylidene fluoride, elongated body having a first end, a second end opposite the first end, a center spline extending between the first end and the second end, and a major outer surface spaced radially outward of the center spline, a ratio of the base material to the poly vinylidene fluoride being greater proximate the center spline than proximate the major outer surface.
A method of forming fibers, the method comprising:
- supplying at least a base material and a polymer vinylidene fluoride to an extruder;
- extruding an elongated body comprising at least the base material and the poly vinylidene fluoride, elongated body having a first end, a second end opposite the first end, a center spline extending between the first end and the second end, and a major outer surface spaced radially outward of the center spline, a ratio of the base material to the poly vinylidene fluoride being greater proximate the center spline than proximate the major outer surface.
