Four kinds of ethylene terephthalate/ethylene isophthalate copolymers (PET/PEI, PEI= 0, 2,
5, 10 mol%) were prepared and melt spun at take-up velocities from 1 to 7 km/min …

The relationships between mechanical properties and superstructure of the poly (ethylene
terephthalate) fiber prepared by a new annealing method called zone annealing method …

Bottle-recycled polyethylene terephthalate (R-PET) fibers were fabricated by the melt
spinning method. Based on characteristics of R-PET chips, this study involved a primary …

An investigation has been made into the mechanism of cold drawing in melt‐spun poly
(ethylene terephthalate)(PET) fibers. An analysis of the cold‐drawing behavior using wide …

Fine structures of high speed spun PET filaments obtained at take-up velocity, 1000-9000
m/min, were investigated by X-ray analysis. Crystalline density calculated from the …

Poly (ethylene terephthalate) fibers were drawn in CO2 (liquid) at 23° C above the critical
pressure followed by a second stage draw≥ 200° C in air. We investigated the effects of first …

In the melt spinning of PET, effects of the variation of flow behavior in the vicinity of spinning
nozzle on the mechanical properties of as-spun fibers and drawn fibers were investigated …

In the present work, the texturability of filament yarns produced from recycled bottle grade
polyethylene terephthalate (R-PET) and new fiber grade PET (FG-PET) were investigated …

In the present work, recycled polyethylene terephthalate (R-PET), virgin fiber grade PET (FG-
PET) and bottle grade PET (BG-PET) chips were spun on a high spinning speed machine …

Elastic filaments have been produced by melt spinning poly (tetramethylene
terephthalate)/poly (tetramethylene ether glycol)‐terephthalate (PTMT/PTMEG‐T) …
