| Abstract: |
| The feather fibers were used as raw material to prepare oil-absorbing paper. The scanning electron microscope was used to explore the effects of the morphology and microstructure of the fibers on the oil and water absorption properties of three feather fibers （large flakes， small flakes， and velvets）. A comparative analysis between feather， wood， and viscose fibers was conducted as well. The results showed that feather fibers had strong adsorption to oily substances， exhibiting strong lipophilic and hydrophobic properties. Acid treatment showed distinct effect on the adsorption performance of feather fibers， when the concentration of sulfuric acid was 2%， the treated feather fibers exhibited good oil absorption effect. With the increase of feather fibers content， the oil absorbency ratio of the prepared oil-absorbing paper increased firstly and then decreased， the oil adsorbency rate increased， and the oil retention rate decreased. When the feather fibers content was 70%， the oil absorbency ratio of the prepared oil-absorbing paper was 25.0 g/g. The oil absorbency ratio of this oil-absorbing paper remained 50% of its original value after repeated use for 6 times. |
