| 20110086948 | NYLON-4 COMPOSITE - The present invention provides a nylon-4 composite containing a nylon-4 resin as a base material, a natural fiber material, and a maleic anhydride graft poly(ethylene-octene) copolymer resin. The nylon-4 composite of the present invention has high heat resistance and impact resistance to provide mechanical properties equivalent or superior to those of the engineering plastics synthesized from petroleum resources. As a result, the nylon-4 composite of the present invention has as excellent properties as the engineering plastics and is an environment-friendly material, thus being useful to make various industrial components including vehicle engine and chassis components. | 04-14-2011 |

| 20090247671 | Solvent-free polyurethane-based artificial leather having the texture of human skin and the preparation method thereof - The present invention relates to a solvent-free polyurethane-based artificial leather having the texture of human skin, and particularly to artificial leather comprising soy protein isolate and solvent-free polyurethane resin, where the use of soy protein isolate provides a higher water content than that of the conventional artificial leather to improve sensitivity properties such as tactile sensation and the use of the solvent-free polyurethane resin provides higher heat resistance and better mechanical properties than those of the conventional artificial leather, without using an organic solvent, thereby enabling to maintain clean indoor air. | 10-01-2009 |
| 20100009146 | HIGHLY INFRARED RAY REFLECTIVE POLYVINYLCHLORIDE ARTIFICIAL LEATHER - The present invention relates to a highly IR (infrared ray)-reflective polyvinyl chloride-based artificial leather, and particularly to a highly IR (infrared ray)-reflective polyvinyl chloride-based artificial leather comprising: (a) a surface layer comprising a black pigment mixture of a perylene black pigment and a carbon black pigment; (b) a foamed layer comprising a white titanium dioxide pigment and polyvinyl chloride resin; and (c) a substrate layer comprising a polyester fiber comprising a white titanium dioxide pigment. The surface layer of artificial leather herein transmits infrared ray while the foamed layer and the substrate layer reflected infrared ray, thereby lowering the temperature increase of the artificial leather of the present invention, and artificial leather herein is pleasant to the touch. | 01-14-2010 |
