| 摘要 |
The present invention relates to manufacture for a high viscosity and high intensity industrial polyester (PET) fiber, and more specifically, to a manufacturing method of an industrial PET yarn, which improves the intrinsic viscosity by adding 0.25-1.00 weight% of CBC, p-BOX and m-BOX capable of chain elongation reaction in the process of melting and spinning conventional PET chips, and has an excellent viscosity and toughness compared to the existing high intensity PET fibers. |
