Kapok fiber which is found in kapok fruit is a kind of seed fiber. Kapok tree is also known as “ceiba pentandra”. Kapok fiber exhibits different profile with its hollow fiber structure, hydrophobic-oleophilic character, low density and buoyancy properties from other cellulosic fibers. It has become an interesting research material thanks to its divergent properties and also its easily accessible, biodegradable, recyclable and reusable nature. Investigations on kapok fibers have demonstrated that a wide range of potential uses of biofuels, electrochemical storage materials, sound and heat insulation materials, removal of various oil-derived wastes from water sources, and even the use of this stated range can be extended. Renewable alternative green sources recently are drawing more attention under sustainability goals. In this respect, kapok fibers shine out as very important source of raw material for many different applications. In this review, fiber structure, fiber properties, application areas of kapok fibers were examined comprehensively.

Oleofilik Buoyans Özellikli Kapok Lifleri ve Yenilikçi Yaklaşımlar

Öz

Kapok lifi, “ceiba pentandra” olarak da bilinen kapok ağacının meyvesi içerisinde bulunan bir tür tohum lifidir.
İçi boş tüp yapısı, hidrofobik/oleofilik karakteri, düşük yoğunluğu ve su üzerinde batmadan yüzebilme kabiliyeti
ile bilinen selülozik liflerden farklı bir profil sergileyen kapok lifleri ayrıca kolay ulaşılabilir, yenilenebilir,
biyobozunur ve tekrar tekrar kullanılabilir olması ile son yıllarda ilgi gören bir araştırma materyali haline gelmiştir.
Kapok lifleri üzerine yapılan araştırmalar, su kaynaklarımıza bulaşan çeşitli yağ türevli atıkların
uzaklaştırılmasından, ses ve ısı yalıtımı malzemelerine, biyoyakıttan elektrokimyasal depolama malzemelerine
kadar geniş bir alanda kullanım potansiyeline sahip olduğunu hatta bu kullanım yelpazesinin daha da
genişleyebileceğini kanıtlar niteliktedir. Sürdürülebilirlik hedefleri altında yenilenebilir alternatif yeşil kaynakların
daha fazla dikkat çekmeye başladığı şu günlerde, kapok lifleri oldukça önemli bir ham madde kaynağı olarak ön
plana çıkmaktadır. Bu derleme çalışmasında; kapok liflerinin yapısı, özellikleri, uygulama alanları gibi başlıklar
detaylı olarak incelenmiştir.
