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.
Claims8
A fiber having a central spline and a major outer surface, said fiber being comprised of about 68-82 wt. % of a hydrophobic polyethylene base material comprised of one or more olefins, about 0.5-22 wt. % of a hydrophilic polymer, and about 10-20 wt. % of maleic anhydride;
- wherein the proportion of the base material to the polymer substantially linearly decreases from the central axis of the fiber to the major outer surface of the fiber.
A fiber, comprising:
- an elongated body comprised of at least about 78-82 wt. % of a hydrophobic polyethylene base material, about 18-22 wt. % of poly vinylidene fluoride, and about 10-20 wt. % of maleic anhydride, the 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, wherein a ratio of the base material to the poly vinylidene fluoride gradually decreases from the center spline to the major outer surface.
