Process of melt-spinning high-molecular-weight ethylene terephthalate polymer |
| abstract |
A process and apparatus are disclosed for melt-spinning highmolecular-weight polyethylene terephthalate into high-performance fibers under conditions which reduce the normally high viscosity of such polyester. Ethylene oxide or other low-boiling oxirane compound is injected under pressure into molten polyester before it is fed to the metering pump of the melt-spinning machine. Illustrations show that injection of amounts as small as 0.3 percent provide a substantial reduction in filter pack pressure. The fibers are characterized by low free-carboxyl content and freedom from voids which might be expected from injection of the volatile material. |
