Conclusions and Future Perspective

As the “low-carbon” concept prevails, abundant kapok fiber has received increasing attention as an eco-friendly textile material for its intrinsic superiorities such as finest and lightest quality, highest hollowness, and most warm nature. With the focus on this green cellulosic fiber, more studies will be carried out to expand the application fields for kapok fiber by combining its higher hollowness and hydrophobic — oleophilic characteristics.
