Latest Patents

Sa Ng Park's latest patents include groundbreaking advancements in fiber technology. One of his patents is titled "Aromatic polyamide fiber free of crystal defect layers perpendicular to." This invention describes a fiber product comprising one or more fibers of aromatic polyamide polymer that possess a microscopic structure of an extended molecular chain. The fibers are free of crystal defect layers perpendicular to the fiber axis, exhibiting a high inherent viscosity of at least 3.0 [dl/g] and a high tensile strength of at least 15 g/d. The inherent viscosity is determined at 30 degrees Celsius using a concentration of 0.5 grams of the polymer in 100 ml of concentrated sulfuric acid.

Another significant patent is "Two-stage process for preparing aromatic polyamide fiber." This process involves dissolving an aromatic diamine and an aromatic diacid chloride in an amide polymerization solvent containing an inorganic salt. A partial polymerization is conducted at a low temperature to form an optically anisotropic liquid crystalline prepolymer dope. This dope is then subjected to a molecular orientating polymerization in a polymerization accelerating-precipitation solvent, resulting in aromatic polyamide fibers that are free of a crystal defect layer perpendicular to the fiber axis and possess high strength and a high degree of molecular orientation.
