3D network structured fiber material


The new standard cushion material that has been adopted for seats of "Shinkansen".

BREATHAIR® is 3D network structured fiber material that rubber-elastic polyether ester elastomer fibers are connected into three-dimensional direction with large numbers of loops.
Since BREATHAIR® was launched in 1996, TOYOBO has been reformed cushion market.


Cushioning properties
BREATHAIR® is highly resilient due to its quick compression recovery, and shows excellent pressure distribution by dispersing deformation stress in all directions of its structure.
Furthermore, BREATHAIR® is superior in durability and heat resistance by using an engineering elastomer "PELPRENE®"
High breathability of BREATHAIR® controls increases in temperature and humidity of the space between sweating human body and a product. In addtion, BREATHAIR® is washable by water because it does not keep much water in the structure.
BREATHAIR® is a recyclable cushion material, because it is made from thermoplastic elastomer. We have already been carried out in-house recycling process of BREATHAIR®. Furthermore, we have also started trial operation of horizontal recycling program by collecting end-of life products made with BREATHAIR®.
