Abstract

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.

BACKGROUND ART Conventionally, fibers made of polymers having various ion exchange abilities have attracted attention as adsorbents in place of activated carbon, zeolite, or ion exchange resins, and many proposals have been made. For example, in Japanese Unexamined Patent Publication No. 51-136590, the length is 6
~15- is disclosed about the fibrous ion exchanger, and the publication states that the fibrous ion exchanger has a spherical shape like an ion exchange resin, and the ion exchange rate is slow, and the ion exchange rate is slow during ion exchange and regeneration. It is described that the p-fibrous material does not have the above-mentioned drawbacks and has a relatively long lifespan, whereas it is easily destroyed by rapid changes in osmotic pressure and the uniform filling is easily disturbed.

However, when fibrous ion exchangers are packed into a column as short fibers, the functional capacity per unit volume decreases due to their bulk, and when liquid is passed through the column after filling, the fibers are compressed into a sheet at the bottom of the column. , pressure loss increases rapidly, and functions such as ion exchange and adsorption deteriorate. On the other hand, in order to avoid this, for example, JP-A-55-t37
As described in Japanese Patent No. 889, ion-exchange fibers in the form of granules in which ion-exchange fibers are fused together not only reduce the large surface area characteristic of fibrous adsorbents, but also When packed in a column, there is a disadvantage that the liquid passing through the column tends to flow unevenly, making it difficult for the liquid to come into uniform and complete contact with the surface of the fibers packed in the column.
