PROBLEM TO BE SOLVED: To solve problems such as the slippage of synthetic fibers on their rewinding when the synthetic fibers such as polyethylene fibers or polypropylene fibers are reacted in a reaction solution in a large apparatus to produce an adsorbent in a large amount, the difficulty of the uniform reaction in the reaction solution when rewound, the production of the products having irregular performances, and the difficulty in the retention of the uniformity.;SOLUTION: The slippage of the synthetic fibers such as the polyethylene fibers or polypropylene fibers is eliminated, when the synthetic fibers are thermally or mechanically crimped and then wound on a bobbin, or the like. In the crimping method, air can be blown on the filaments to fuzz the filaments. The crimped fibers can be rewound on a bobbin or cheese-like tool to react the fibers. Since the fibers can softly be wound, the inner and outer portions of the wound fibers can uniformly be reacted.;COPYRIGHT: (C)2005,JPO&NCIPI
