  • Patent number: 11186236
    Abstract: A sheet for an automobile interior/exterior material provides excellent sound absorption performance. A sheet for an automobile interior/exterior material, which comprises a nonwoven fabric layer in which a fiber weight is 220 g/m2 to 1,000 g/m2 and an olefin resin layer laminated on one surface of the nonwoven fabric layer. The formation amount of the olefin resin layer is within a range from 100 g/m2 to 500 g/m2, the melt flow rate of the olefin resin is within a range from 1 g/10 minutes to 90 g/10 minutes. The nonwoven fabric layer is impregnated with at least a part of the resin in the olefin resin layer, the olefin resin layer is provided with a plurality of micropores. The sheet for an automobile interior/exterior material as a whole has air permeability of 1 to 60 (cm3/cm2·second) in the thickness direction.

  • Publication number: 20090093359
    Abstract: A fiber fabric having a VOC removing function according to the present invention has a hydrophobic inorganic porous substance and a photocatalyst adhered to at least a part of the fiber fabric with binder resin. With this, not only formaldehyde and acetaldehyde but also VOCs having an aromatic ring such as toluene and xylene can be adequately decomposed, which prevents cross-contamination by intermediate products formed during the decomposition.

  • Patent number: 7306660
    Abstract: A cationized supporting material 2 is immersed into a treatment solution containing a level dyeing agent, and then immersed into a treatment solution containing a metal phthalocyanine complex and then dried to thereby obtain an odor eliminating material 1. Alternatively, a cationized supporting material 2 is immersed into a treatment solution containing a metal phthalocyanine complex and a migration inhibitor and then dried to thereby obtain an odor eliminating material 1. The odor eliminating material exerts excellent odor elimination performance against ammonia, hydrogen sulfide, methyl mercaptan, acetic acid and acetaldehyde.
