Latest Patents

Guangkun Song's most recent patents include the "High-modulus low-shrinkage polyester industrial yarn and its preparation method" and the "High-uniformity coloured polyester industrial yarn."

The first patent describes a high-modulus low-shrinkage polyester industrial yarn that is achieved through a sophisticated process involving dissolution, washing, solid-state polycondensation, and spinning. This yarn features an impressive dry heat shrinkage rate of 2.0±0.25% at testing conditions of 177°C for 10 minutes with a pressure of 0.05 cN/dtex. Notably, it has a fiber modulus measuring at least 100 cN/dtex, indicating its strength and durability. The polycondensation catalyst utilized in the process includes magnesium ethylene glycol and antimony ethylene glycol, both of which boast a small thermal degradation coefficient, making the yarn suitable for various high-performance applications.

The second patent, focusing on the high-uniformity coloured polyester industrial yarn, revolves around a modified polyester created from terephthalic acid segments, ethylene glycol segments, and branched diols. This innovative yarn is produced through a series of esterification reactions and polycondensation processes, which are executed under controlled conditions using concentrated sulfuric acid as a catalyst. The resultant yarn not only exhibits high uniformity in color but also maintains desirable physical properties, thanks to the meticulous preparation techniques employed.
