HOLLOW FIBER MEMBRANE CARPET MANUFACTURING METHOD, AN ELEMENTARY HOLLOW FIBER MEMBRANE CARPET MEMBER AND HOLLOW FIBER MEMBRANE CARPET

摘要

A method of manufacturing a hollow fiber membrane carpet includes the steps of laying out a multiplicity of hollow fibers, forming a pair of strips of non-permeable adhesive material on the hollow fibers in a transverse relationship thereto and in a spaced relationship from one another such that main portions of the hollow fibers extend between the spaced strips, cutting selected portions of the hollow fibers adjacent to the spaced strips so as to open the hollow fibers to communication at least at one of a pair of opposite end portions of the hollow fibers, and assembling the hollow fibers and spaced strips into a plurality of elementary carpet members and thereafter into a hollow fiber membrane carpet. Assembling the carpet is performed by bringing and attaching the strips together in a side-by-side relationship so as to form the elementary carpet members each having an elongated base element formed by the attached strips and a multiplicity of loops formed by the hollow fibers with the main portions thereof extending from the base element and the opposite end portions thereof supported in the base element, and then positioning together the elementary carpet members to provide the hollow fiber membrane carpet by attaching in side-by-side relationships the base elements of adjacent elementary carpet members to form a support base of the hollow fiber membrane carpet with the hollow fiber loops extending outwardly from a side of the support base.
