COMPOSITE FIBER STRUCTURE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a composite fiber structure capable of enhancing the collection efficiency of a harmful substance or dust smaller than the size of the gaps between fibers by selectively laminating extremely fine fibers on the gaps between the fibers constituting a fiber structure while holding a sufficient filtering capacity and extremely enhancing a filtering capacity by imparting conductivity to the constituent fibers. SOLUTION: Extremely fine fibers wherein the diameter of a single fiber is 1-3,000 nm are laminated on the fiber structure constituted of fibers charged so as to attract the charged single fibers constituting the extremely fine fibers to form the composite fiber structure wherein the extremely fine fibers are selectively brought into contact with and laminated on the surfaces of fibers constituting the fiber structure.
