A sustainable approach to oil spill cleanup by kapok and waste cotton needle punched nonwoven blends

Hollow polyester/kapok/hollow polyester fiber-based needle punched nonwoven composite materials for rapid and efficient oil sorption

“…Compared to the previously prepared nonwoven oil absorbing materials, the hollow PET/kapok/hollow PET nonwovens exhibit enhanced mechanical properties. 13 The distribution of both kapok and hollow PET fibers is mostly random. However, the fibers trend to align more along the machine direction due the movement of the web curtain, which leads to a higher stress in MD.…”

“…Therefore, two types of bers need to combined to maximize their individual advantages. 13,14 Kapok ber, as a natural material, is known for its high hollowness, which enables it to efficiently absorb and retain oil. 15 Kapok ber is non-toxic, as it does not pollute the ecosystem and has a high recovery rate.…”

“…Despite having a good oil sorption performance, the mechanical properties of the nonwovens were not enhanced. 13 In a study by Lee et al , blending kapok and polypropylene (PP) fibers during carding was used to investigate the oil sorption capacity of needle-punched nonwovens. They found that the PP/kapok blend (50/50) sample exhibited the highest synergy effect, having the lowest bulk density and the best oil sorption capacity.…”

Recent advances of textile sorbents for oil spills cleanup: A review

“…Singh et al, 178 obtained a novel blended nonwoven sorbent compound of (10/90, cotton/kapok) fibers using needle-punching and carding techniques. Their results showed that the WCA of the sorbent was high (∼147°) due to the high ratio of more hydrophobic The oil adsorption ratio for studied samples.…”

Non-woven sorbent based on recycled jute fibers for efficient oil spill clean-up: From production to biodegradation

“…On the other side, agro-industrial residues such as banana and orange peel, sugarcane bagasse, rice husk, peat moss, saw dust, barley straw, or natural fibers such as cotton, jute, kapok, wool, coconut etc. are biodegradable, abundant and inexpensive (Choi and Kwon, 1993;Lim and Huang, 2007;Radetić et al, 2007;Husseien et al, 2008a;Dong et al, 2015;Thilagavathi et al, 2018;Thilagavathi and Karan, 2019;Asadpour et al, 2021;Vijayasekar and Saravanan, 2022;Cardoso et al, 2021;Hakeim et al, 2022;Wang et al, 2022;Singh et al, 2023) and have been examined as sorbents. These biosorbents can be disposed in many ways, including composting (Husseien et al, 2008b).…”
