ABSTRACT
In this work an attempt has been made to produce kapok/polypropylene (80/20) needle punched nonwoven for oil spill clean-up process. The difficulties involved in structuring kapok fiber through needle punching process and hence to develop a nonwoven are discussed. As an outcome, hydrophobic-oleophilic kapok fiber nonwoven has been produced and characterized for its oil sorption and retention. The maximum oil sorption was found to be 40.80 g/g and 29.0 g/g for high density oil (HD) and diesel oil respectively which is higher than the commercial polypropylene based oil sorbent pad. An interesting observation found was its retention value ranging from 0.88 to 1.00 which makes it an alternative for synthetic sorbents. The burning test of the oil sorbed samples ended up with only less amount of ash residue confirming its suitability and eco-friendly nature.
摘要
本研究旨在生产用于清理过程的木棉/聚丙烯（80/20 %）针刺非织造布。讨论了通过针刺工艺制造木棉纤维的困难，并讨论了非织造布的开发。作为一个结果，木棉纤维非织造布具有疏水亲油产生和特点的油吸附和滞留。高密度油（HD）和柴油的最大吸油率分别为40.80克和29克，高于商业聚丙烯基吸油垫。一个有趣的观察发现，它的保留值范围从0.88到1，这使得它成为合成吸附剂的替代品。油吸附样品的燃烧试验只剩下少量的灰渣，证实了它的适宜性和生态友好性。
