"Anti-Mite-Allergen Processed Seat Fabric" employed in new Crown

Komatsu Seiren (Nomi-shi) has jointly developed "Anti-Mite Allergen Processed Seat Fabric," an automotive seat fabric that suppresses mite allergens with the potential to cause allergic reactions, with Toyota Boshoku Corporation (Kariya-shi, Aichi Prefecture) and Sekisui Chemical (Osaka-shi). It is employed in the seats of the new "Crown" launched by Toyota Motor Corporation (Toyota-shi, Aichi Prefecture) in February.

With special technology, this "Anti-Mite Allergen Processed Seat Fabric." is impregnated the anti-allergen agent "ALLER BUSTER®" developed by Sekisui Chemical. This not only reduces the activity of mite allergens brought inside the vehicle by passengers by about 98% but also provides long-term sustained effective suppression. With water as the solvent used to dissolve the base substance "ALLER BUSTER®" is an environmentally-friendly product.

Anti-allergen agent is applied from the undersurface of the fabric to provide suppression of mite-allergen activity with no loss of the original feel or design including the color of the seat fabric.

Since application to the undersurface inevitably reduces the detoxification performance, compared to application to the top surface, Komatsu Seiren's original manufacturing control ensures that the anti-mite-allergen agent permeates into the interior of the fabric. As a result, the process of passengers getting in and out of the automobile together with vibration occurring when the automobile is in motion ensures that allergens pass through gaps in the fabric and fall to the underside where they are absorbed by the anti-mite allergen agent and suppressed.
