蒲绒纤维复合絮片的制备与油液吸附性能

Preparation and oil adsorption performance of cattail fiber wadding

为了探究蒲绒纤维非织造材料对纯油液及油水混合液的吸附性能,制备了不同纤维品种、絮片结构及纤维混合比例的蒲绒复合絮片,分别对其在纯油液和油水混合液里的吸附性能进行测试及分析。结果表明:蒲绒纤维复合絮片对纯油液和油水混合液吸附倍率都高于20 g/g,在纯油液中的保油率高于90%,但在油水混合物中的保油率降至68%。随着厚度的增加及蒲绒纤维混入比例的增多,复合絮片的吸附能力和储油能力增强;但聚丙烯纤维的混入,会使复合絮片的保油率下降;木棉纤维的油液吸附能力要优于蒲绒纤维及聚丙烯纤维。通过调整纤维混合比例和复合絮片孔隙结构,蒲绒纤维复合絮片将获得更好的油液吸附效果。

To study the adsorption to pure oil and oil-water mixture,cattail fiber waddings with different fibers,wadding structures,blending ratios were prepared.Oil absorbencies in the pure oils and oil-water mixtures were tested and evaluated.The analysis showed that cattail fiber waddings have better adsorption performance to pure oil and oil-water mixture,which is higher than 20 g/g.The retention rate of pure oil is higher than 90%,while retention rate of oil-water mixture decreases to 68%.With the increase of wadding thickness and cattail ratio,the oil adsorption and retention of composite waddings are heightened.The oil-retention declines with the blending of polypropylene(PP)fiber.The oil adsorption of kapok fiber is better than that of cattail fiber and PP fiber.Therefore,oil adsorption performance is improved through adjusting the fiber ratio and porous structure.
