Latest Patents

Among his latest patents, Cho has developed "Unspun acrylic staple fibers." This invention involves a highly-oriented acrylic staple fiber prepared by simple extrusion of a PAN/H₂O melt in a gel crystalline state without spinning. The acrylic fibers exhibit remarkable properties, including a degree of orientation between 80 and 97% as observed by X-ray diffraction. The fibers have a length distribution ranging from 5 to 500 mm and a thickness distribution from 5 to 500 µm, with a length to thickness ratio ranging from 100 to 100,000 determined by a scanning electron microscope. Additionally, they possess a tensile strength of 10 to 70 kg/mm², an initial tensile modulus of 300 to 1,500 kg/mm², an elongation of 5 to 20%, and a specific surface area of 1 to 50 m²/g.

Another notable patent is for "Pulp-like short fibers from liquid crystal polyesters." These fibers are prepared from liquid crystal polyesters capable of forming an anisotropic melt phase at temperatures between 200°C and 400°C, with a molecular weight ranging from 2,000 to 100,000. The fibers consist of microfibrils and exhibit highly-oriented fiber characteristics and properties.
