Low-emission skin material
A low-emission skin material of the present invention comprises a decorative layer made of a fibrous substance comprising 60% by weight or more of bright fiber based on the total weight of the fibrous substance; a reflective layer laminated to the decorative layer and capable of reflecting visible radiation, near-infrared radiation, mid-infrared radiation and far-infrared radiation; and a support layer laminated to the reflective layer to support the reflective layer.
1. A low-emission skin material, comprising:
a decorative layer made of a fibrous substance comprising 60% by weight or more of bright fiber based on a total weight of the fibrous substance;
a reflective layer laminated to the decorative layer and capable of reflecting visible radiation, near-infrared radiation, mid-infrared radiation and far-infrared radiation transmitted through the decorative layer; and
a support layer laminated to the reflective layer to support the reflective layer,
wherein the fibrous substance is colored with at least one of organic pigments and organic dyes.
2. The low-emission skin material according to claim 1 , wherein the bright fiber is comprised in an amount of 75% by weight or more based on the total weight of the fibrous substance.
3. The low-emission skin material according to claim 1 , wherein the fibrous substance is one of a woven fabric and a nonwoven fabric having a density ranging from 5 to 500 g/m 2 .
4. The low-emission skin material according to claim 1 , wherein the bright fiber is made of at least one polymeric compound selected from the group consisting of polyesters, polyolefins, polyacrylonitriles, polyamides and copolymers thereof.
5. The low-emission skin material according to claim 1 , wherein the fibrous substance has a fiber size ranging from 0.1 to 15 denier.
6. The low-emission skin material according to claim 1 , wherein the reflective layer is made of one selected from the group consisting of a metallic film, a metallic foil and metallic flakes, the support layer is made of one of a resin film and a nonwoven fabric, and the reflective layer is kept smooth by the support layer.
7. The low-emission skin material according to claim 6 , wherein the reflective layer is made of a metallic film, the support layer is made of a resin film, and the metallic film is formed by vapor deposition of one of aluminum and aluminum alloy onto the resin film.
8. The low-emission skin material according to claim 1 , wherein the reflective layer has a far-infrared emissivity of 0.5 or less.
9. An interior trim component, comprising the low-emission skin material as set forth in claim 1 .
10. The interior trim component according claim 9 , further comprising a substrate laminated to the support layer of the skin material.
11. The interior trim component according to claim 10 , wherein the substrate is made of one selected from the group consisting of woven fabrics, nonwoven fabrics, resin films, corrugated cardboards and resin felts.
12. A method of producing the low-emission skin material as set forth in claim 1 , the method comprising:
preparing the decorative layer using the fibrous substance;
coloring the fibrous substance with at least one of organic pigments and organic dyes;
providing the support layer;
forming the reflective layer on the support layer; and
laminating the decorative layer to the reflective layer.
13. The method according to claim 12 , wherein said preparing includes spinning at least one polymeric compound selected from the group consisting of polyesters, polyolefins, polyacrylonitriles, polyamides and copolymers thereof into the bright fiber.
14. The method according to claim 12 , wherein said preparing includes forming the bright fiber into one of a woven fabric and a nonwoven fabric having a density ranging from 5 to 500 g/m 2 with the use of the bright fiber.
15. The method according to claim 12 , wherein said forming is carried out by one of vapor deposition and sputtering of metal onto the support layer.
16. The method according to claim 12 , wherein said forming is carried out by bonding a metallic foil to the support layer with an adhesive.
17. The method according to claim 12 , wherein said forming is carried out by preparing a dispersion of metallic flakes, a resin and a hardener and applying the dispersion to the support layer.
18. The method according to claim 12 , wherein said laminating is carried out by flame lamination.
19. The low-emission skin material according to claim 4 , wherein the bright fiber is made of at least one polymeric compound selected from the group consisting of polyolefins and polyacrylonitriles.
