| titleOfInvention | Manufacturing method of polyester multifilament yarn, polyester multifilament yarn manufactured therefrom and polyester tire cord comprising the same |
| abstract | The present invention relates to a process for producing industrial polyester multifilament yarns, polyester multifilament yarns produced therefrom and polyester tire cords comprising the same, more particularly comprising a) at least 90 mol% of ethylene terephthalate units To prepare a discharge yarn by melt spinning the polyester chip having an intrinsic viscosity of 0.85 ~ 1.3 at a spinning temperature of 290 ℃ or less, b) passing the discharge yarn through a delayed cooling zone and quenching and solidifying to produce a polyester partially drawn yarn (POY yarn), and c) the polyester partially drawn yarn (POY yarn) at a total draw ratio of 2.5 times or less. Provided is a method for producing an industrial polyester multifilament yarn comprising stretching, a polyester multifilament yarn produced therefrom, and a polyester tire cord comprising the same.n n n Polyethylene terephthalate, polyester multifilament yarn, low temperature spinning, tire cord |
