Non-woven water-repellent sound-absorbing material
It's pulp, but it doesn't absorb water!?
Remarkably, we have developed a water-repellent sound-absorbing material made of pulp non-woven fabric that completely floats on water and even rises when pressed down with a finger. This sound-absorbing material, characterized by its almost non-existent water absorption, is made from a porous material called "airlaid based on pulp." It is ideal for areas where water absorption is not acceptable. Specifically, it is suitable for sound-absorbing materials covering components that may condense or in environments with high humidity. Our manufacturing method uses pulp as the main raw material to create a porous structure with a high bulk and void ratio that absorbs sound. Among porous sound-absorbing materials, the surface of natural pulp not only has a special structure called microfibrils but also, due to its hollow structure, secures air layers within the fibers, which is expected to provide unique sound-absorbing effects different from other materials.
