PURPOSE:To obtain excellent ion exchange fibers free from clogging by using an assemblage of continuous filament lines having ion exchange groups as a fiber adsorbing material and melt-sticking both ends thereof. CONSTITUTION:A fiber assemblage of continuous filament lines having ion exchange groups which is of a columnar or cylindrical shape of about 3-30mm. length wherein fibers are melt-stuck in both end parts is used as an adsorbing material made of fiber for exchanging of low molecular ions, adsorbing and desorbing of middle and high polymer materials, etc. If the ion exchange fibers of such specific shapes are used for the adsorbing material, clogging and pressure drop are eliminated without losing the advantages of the ion exchange fibers having high surface areas and high ion adsorbing power, etc. |
