A sound-absorbing and heat-insulating material made from natural Kapok fiber (developing product)
We are considering the development of automotive soundproofing materials that support SDGs using the natural material "Kapok".
■What is Kapok?
Kapok (scientific name: Ceiba pentandra) is a deciduous tall tree belonging to the genus Ceiba of the family Malvaceae, and is native to Southeast Asia. The fibers obtained from nuts of Kapok are hollow, and while they are lightweight and water-repellent, they also have the drawback of being flammable. In the past, this fiber was used for bedding and apparel (in recent years, it has been replaced by synthetic fiber due to cost considerations).
■Development of soundproof material using Kapok fiber
Kapok fiber is hollow inside and has a small diameter, so it can be expected to form a large amount of air layer, and demonstrate high sound absorption and heat insulation performance. But the fiber length is short and it is difficult to maintain the shape by itself, so it is necessary to combine it with other materials. We are developing in-vehicle soundproofing materials using Kapok fiber by utilizing our own press molding technology.
・High sound absorption/insulation performance: Hollow ratio 70-80%
・Light weight: Weight is 1/8 of cotton
・Environmental friendly, contributing SDGs
■We are looking for partners!
・Those who have textile processing technology
・Sales expansion partner outside the automotive field
・Those who are interested in contributing to the SDGs
