The density and crystallinity of polyester fiber were measured on the moving threadline
during the melt spinning process. The density was calculated by applying the continuity …

The physical and mechanical properties of these filaments were studied as a function of
molecular weight. The following results were obtained.(1) Until the take-up velocity reaches …

High‐speed melt spinning of poly (ethylene terephthalate) was performed using a spinning
nozzle with an inserted metallic wire of various lengths (0, 8, 30, and 45 mm). The molecular …

The high‐speed melt spinning of sheath/core type bicomponent fibers was performed and
the change of fiber structure with increasing take‐up velocity was investigated. Two kinds of …

Melt‐spun poly (trimethylene terephthalate)(PTT) fibers were zone‐drawn and the structures
and properties of the fibers were investigated in consideration of the spinning and zone …

Blends of polyethylene terephthalate (PET) and polyethylene naphthalate (PEN) were melt
spun using a high‐speed winding process in a single‐screw extruder combined with a …

Five different poly (ethylene terephthalate)(PET) materials (two recycled and three virgin
ones) were melt-spun into fibres using a capillary rheometer and aerodynamic stretching. In …

High molecular weight poly (ethylene terephthalate)(PET) was obtained by solid‐state
polymerization of solution‐grown crystals of PET that were prepared from commercially …

From an industrial point of view, it is effective to have a relation between process conditions
and resulting product properties. In practice there are many possible process conditions …

The correlation between the fiber structure and mechanical properties of two different poly
(ethylene terephthalate) fiber types, that is, wool and cotton types produced by three …
