Abstract: The present invention relates to a food container with a reduced amount of elution of hazardous substances. As the food container according to the present invention has a structure in which a foamed layer and a PETG resin layer are laminated, compressive strength is improved and moldability is excellent, so that the food container may be provided in various sizes and shapes. Moreover, the present invention has a harmless effect to a human body due to a remarkably low amount of elution of hazardous substances.

Abstract: The present invention relates to interior and exterior materials for an automobile, comprising: a polyester resin foam layer; and a fiber layer laminated on one side or both sides of the polyester resin foam layer. The interior and exterior materials for an automobile can enhance durability and strength, reduce weight, and improve a work environment.

Abstract: Provided are an automobile interior/exterior material including a low-melting-point polyester resin fiber layer, and a method of manufacturing the same. More particularly, an automobile interior/exterior material having excellent processability and price competitiveness without deterioration of properties, such as strength and durability, is provided.

Abstract: The present invention relates to a polyester composite comprising: a polyester foam sheet; and a polyester resin layer laminated on one surface or both surfaces of the polyester foam sheet. The durability and strength of the composite can be improved, the weight of the composite can be reduced, and the composite can be variously utilized as vehicle interior and exterior materials.

Abstract: The present invention relates to a composite of a multilayer structure comprising a polyester foam and a polyester resin layer, and a use thereof. A polyester composite according to the present invention provides a composite which is capable of improving a working environment, improves durability and strength and has light weight; is easy to reuse; and can be variously utilized for different uses such as a vehicle interior or exterior material or building insulation materials.

Abstract: The present disclosure relates to a polyethylene fiber and a method for preparing thereof, and more particularly to a polyethylene fiber, a method for preparing thereof, and an apparatus for preparing thereof, which has excellent wearing and touch sensation with processing convenience into woven fabrics and knitted fabrics in use in applied products by reducing the stiffness of fiber having the same physical properties using an enforced necking method in a spinning process.

Abstract: The present invention relates to a compound for preparing a copolymerized polyester resin and a method for preparing a copolymerized polyester resin using the same. The method for preparing a copolymerized polyester resin according to the present invention uses a compound represented by chemical formula 1, thereby exhibiting an excellent effect and reducing the manufacturing cost. In addition, the resin thus prepared has excellent thermal adhesion even at low temperatures and generates few byproducts during a polymerization procedure, so that the resin is advantageous in view of workability and processability.

Abstract: Disclosed is a polytrimethylene terephtalate conjugate fiber having high self-crimpability, which is prepared by conjugate-spinning two types of polytrimethylene terephtalates having different intrinsic viscosities in which a difference between the intrinsic viscosities ranges from 0.05 to 0.15 into a side-by-side fiber. Also, the polytrimethylene terephtalate conjugate fiber prepared by the conjugate-spinning undergoes a false twisting process, leading to development of three-dimensional high self crimpability and sufficient bulky property in the resulting fiber.
