Abstract
A hollow fiber dialyser comprises a webbing of hollow fibers. A loose warp hread at each end of a webbing wound on a core, acts as a wick barrier to prevent sealant from leaking into the interstices between the hollow fibers. A tight warp thread nearest the open ends of the fibers pinches off the free inner cross section of each hollow fiber to prevent sealant from penetrating into the hollow fibers.
