Abstract
A papermaker's fabric constructed from polymeric fibers with 15 percent or more of the fabric'fibers larger than 100 denier and multipolymeric, the multipolymeric fibers containing two or more distinct polymeric regions within their cross sections. The multipolymeric fibers may be constructed in a sheath-core, side by side, or islands in the stream form. The components of the multipolymeric fibers are each selected to provide a combination of properties not available from any single polymer fiber.
