Abstract: A fibrous adsorbent for VOC absorption using a fiber precursor composition and a manufacturing method thereof are provided to offer excellent adsorption capacity of volatile organic compounds rapidly. A manufacturing method of a fibrous adsorbent for VOC absorption using a fiber precursor composition includes the following steps of: producing a fiber precursor compound by adding a fibrous adsorbent for VOC absorption using a fiber precursor composition 0.1 ~ 5 weight% in polyacrylo nitrile resin dissolved liquid after dissolving polyacrylo nitrile resin in a solvent; producing the fiber by adding voltage of 20 ~ 30kV with the fiber precursor compound; stabilizing the fiber in air atmosphere for 0.5 ~ 3 hours; carbonizing the oxidized and stabilized fiber in the inert atmosphere or a vacuum state to temperature of 800 ~ 1000°C; and activating the carbonized fiber in the steam atmosphere.
