… study conducted on-line measurement of the fiber velocity and thickness of the spin line of
flat and hollow fibers and analyzed the change of cross-sectional shape along the spin line. …

… Other measured temperatures at the same line are compared with the maximum. The number
of pixels indicating temperatures between ambient and fiber temperature are counted and …

… the on-line measurements of the spinning behavior in high-speed melt spinning process (1).
We also have carried out diameter and temperature measurements of the spinline paying …

… of the melt spinning process have been published recently. Ziabiclci (1) dealt theoretically
with the molecular orientation during spinning process and measured birefringence of wound …

… In measuring pA(z) we used the instrument shown in Figure 11 to trap a segment of polymer
… line in Figure 16 is identical with l(x), curve (1) in Figure 14. Assuming that the solid line in …

… In the nylon 6 melt spinning process at speeds of 900 and … the takeup machine are also
measured as function of quench … a molecular oscillation along the spinning line rather than a …

… On-line measurements were made of filament temperature profiles (DuPont proprietary IR
gage), … The relative viscosity (RV) was used as a measure of the molecular weight and was …

… melt spinning of synthetic fibers. Tension in the fiber and fiber temperature, diameter, and
x-ray diffraction patterns are measured … down the spinline. Further evidence of a “skin effect” in …

… curve (SOC = 0.645 denier/g) is derived from direct spin line stress measurements by Garg
(26) over the entire range of our results. In these experiments, Garg located the freeze point …
