    Abstract: In a gas-barrier aluminum deposition film according to one embodiment of the present invention, a seed coating layer containing functional groups of at least one type selected from among a hydroxyl group (—OH), an amine group (—NH), and a carboxylic acid group (—COOH) is formed on a thermoplastic plastic base film to form a seed molecular layer that enables uniform deposition of aluminum, such as AlOx or AlNx, through chemical reaction, on a surface of the coating layer, with aluminum atoms vaporized at the initial stage of aluminum deposition, thereby inducing uniform deposition of an aluminum layer to be subsequently deposited. Therefore, it is possible to provide a deposited film having superior oxygen and water vapor barrier properties compared to existing aluminum deposition films.

    Abstract: Provided are a monovalent anion selective ion exchange membrane and a method of manufacturing the ion exchange membrane. In regard to the monovalent anion selective ion exchange membrane, a surface portion thereof has a high amount ratio of a cation exchange polymer electrolyte, a central portion thereof has a high amount ratio of an anion exchange polymer electrolyte, and an amount ratio of the anion exchange polymer electrolyte with respect to the cation exchange polymer electrolyte continuously increases in the thickness direction thereof from the surface toward the center. Due to this structure, compared to monovalent anions, polyvalent anions may permeate much less through the exchange membrane. Thus, high selectivity for monovalent anions may be obtained.

    Abstract: A nonwoven fabric having improved air permeability and manufacturing method thereof are presented. The nonwoven fabric has improved air permeability and is formed with long fiber nonwoven fabric of single or multi layer, wherein the long fiber nonwoven fabric is produced by spinning polytrimethylene terephthalate having viscosity of 0.8 to 1.2 and polyethylene terephthalate having viscosity of 0.6 to 0.8 to sheath/core shape with using each spinneret pack which can spin filaments having different denier from each other and arranged in parallel with each other, and then heat pressing with free-embossing or embossing pattern to bind the filaments.The nonwoven fabric has excellent air permeability, softness and resistance, which are required for nonwoven fabric sheets used for various purposes as well as their economical production.

    Abstract: The present invention enables a polycondensation reaction of polyester at a low temperature to lead to an improvement in thermal stability as well as a high degree of polymerization in a polyester resin, so that a polyester resin with a minimized end group (carboxyl group) and a small content of foreign matter can be produced. In addition, when a film is manufactured using the polyester resin, a film with a uniform thickness can be produced because no gap is formed between the drum surface and a sheet-like product even at a high rotational speed due to an excellent electrostatic application property and a small melt specific resistance of the polyester resin, and a film with high transparency can be produced due to a small content of foreign matter.
