Title: The Innovative Contributions of Duk-ho Oh
Introduction
Duk-ho Oh is a prominent inventor based in Ulsan, South Korea. He has made significant contributions to the field of polymer technology, particularly in the manufacturing of polyester fibers. With a total of 3 patents to his name, his work has had a substantial impact on the industry.
Latest Patents
Duk-ho Oh's latest patents include a method for manufacturing polyester fibers. This innovative method involves melt-extruding a polymer without increasing its intrinsic viscosity during spinning. This approach minimizes the reduction of intrinsic viscosity and maintains a low atmospheric temperature directly below the nozzle. This technique maximizes the degree of orientation of undrawn yarn and allows for winding the polymer at speeds of 2,000 m/min or more. The result is high-strength, low-shrinkage polyester fibers with uniform fineness and physical properties, produced efficiently without the formation of broken or curved filaments. Additionally, he has developed a polyester multifilament yarn characterized by high modulus and low shrinkage. This yarn provides a treated cord with high tenacity and improved dimensional stability, making it ideal for use as a fibrous reinforcement material in rubber products such as tires and belts.
