Kapok, a sustainable material made from tree nuts

We used cotton harvested from the nuts of the kapok tree, a tree that grows naturally in the tropical regions of Southeast Asia. Kapok is an eco-friendly material cultivated with little fertilizer and water without pesticides. It is said to be the lightest natural fibre in the world, approximately one-eighth the weight of cotton. The fibre is hollow and contains a lot of air, so it is light and warm.

What is Kapok ?

Kapok Forest

Kapok is a tall deciduous tree that is often cultivated in Indonesia, Thailand, and India. The plant requires little pesticides, fertilizers, and watering, it grows in sunlight and rainwater. In the forests of Java Island, Indonesia, where MUJI produces kapok, trees are systematically planted at intervals of about 5 meters and cultivated in conditions close to nature.

Reduction of Environmental Impact

Unlike other fibers such as cotton and linen, kapok does not need to be mowed when harvesting. As it continues to grow, it grows taller and larger, and absorbs carbon dioxide converting it into oxygen. The entire tree performs photosynthesis, so the entire forest absorbs a large amount of CO2 helping to reduce the cause of global warming.

Sustainable Material

Previously, use of Kapok's fibers were short and unsuitable for use as yarn. In recent years, spinning has become possible due to the development of new technologies, and it is a sustainable material that is attracting attention as yarn making, weaving, and clothing manufacturing are being promoted.
