▎ 摘　　要

NOVELTY - Recycling white oil in the production process of ultra-high molecular weight polyethylene fiber, comprises (i) filtering using porous material as filler to adsorb and remove the solid impurities in the white oil to obtain filtered white oil, (ii) decoloring using decoloring agent as filler to absorb and decolor the filtered white oil obtained in step (ii) to obtain the recycled white oil. USE - The method is useful for recycling white oil in the production process of ultra-high molecular weight polyethylene fiber. ADVANTAGE - The method utilizes microporous material and decolorizing agents which are both in the form of fillers, which improves the overall decolorization efficiency.
