A hollow fiber assembly having a selective permeability including cylindrical arrangements of hollow fibers having selective permeability comprising mainly a cylindrical layer of hollow fibers formed by a crisscross arrangement of hollow fibers, a hollow portion which exists inside the above cylindrical layer of hollow fibers, a plurality of engaging members which are respectively separated from one another in said hollow portion, a resin wall (A) which is disposed at an open end of said hollow fibers and arranged to be open to the exterior without leaving any space between said fibers and with separation from said engaging means, a resin wall (B) which is disposed at the other end of said assembly for fixing the end of said assembly, an elastic supporting member for controlling the distance between the two resin walls (A) and (B), and a fluid supply conduit.

A hollow fiber assembly having selective permeability consisting essentially of in combination a cylindrical arrangement of multilayers of a plurality of spirally wound flattened, tape-form hollow fibers having selective permeability, said layers of fibers being crisscrossed in a parallel relationship one to the other, at least two core sections centrally located within said cylindrical arrangement of said multilayers of hollow fibers, each of said core sections comprising an engaging member defining a hollow portion, each respective core section being separated and spaced one from the other, a first fluid-tight resin wall disposed at a first end of said assembly in which said hollow fibers terminate such that said hollow fibers open to the exterior of said resin wall, said first resin wall being separated and spaced from said engaging members, a second resin wall disposed at and fixing together a second end of said assembly, said cylindrical arrangement of hollow fibers extending continuously between said first resin wall and said second resin wall, an elastic support means for controlling the distance between said first and second resin walls and a fluid supply conduit means for introducing a fluid to be treated into said hollow fiber assembly.
