A mass transfer device including a hollow fiber bundle wound on a core for radially outward flow of a first fluid. The core has an axis extending from one end to the other. The hollow fiber bundle has packing fractions which increase radially outward of the core's axis for a major portion of the bundle. Methods for making such mass transfer device.

[ We claim:] [16.] A mass transfer device comprising:a hollow fiber bundle wound around a supporting core, said core having a first end, second end and an axis extending from said first end to said second end, said hollow fiber bundle extending radially outward relative to the axis of the core and having packing fractions which increase radially outwardly in a major portion of said hollow fiber bundle thereby providing a packing fraction gradient, said hollow fiber bundle further comprising fibers each having a first end, a second end, a hollow interior and a semi-permeable wall wherein the first ends of said fibers are adjacent the first end of said core and the second ends of said fibers are adjacent the second end of said core;an outer housing surrounding said hollow fiber bundle;a first fluid inlet operatively connected to a region of the hollow fiber bundle adjacent to the core and a first fluid outlet operatively connected to a region of the hollow fiber bundle adjacent to the housing such that said first fluid is caused to flow from the core radially outward through the hollow fiber bundle;a first potting element adjacent the first ends of said fibers, the first potting element configured to seal said fibers to said core and housing;a second potting element adjacent the second ends of said fibers, the second potting element configured to seal said fibers to said core and housing, wherein said first and second potting elements, core and housing define an enclosed chamber; anda second fluid inlet operatively connected to the interior of said fibers at one of said first ends and second ends and a second fluid outlet operatively connected to the interior of said fibers at the other of said first ends and second ends..Iaddend..Iadd.
