Abstract: A method monitors and measures the uniformity of tows with mechanical sensing elements in the course of production on a tow line. The tension of the running tow is measured upstream of a transport roll arrangement and is utilized as a measure of the uniformity of the tow. Irregularities in the tow result in tow tension determination outside a predetermined tension range, and when the determined tension measurement is outside that range the irregular tow portions are remove. Also, the frequency of tow tension determination outside a predetermined range may be used as an indication of tow quality and for removing substandard tows.

Abstract: Asymmetric fluoropolymer hollow fibers having a thin, dense, inner separation layer that is essentially defect-free. In the process of this invention, a fluoropolymer dope is spun into a hollow fiber using a hollow fiber die, a core solvent, preferably comprising water, and a coagulation bath, preferably comprising a water-acetone mixture. Due to solubility and surface tension differences, the outer layer of the fiber does not coagulate quickly enough to form a dense layer, and remains porous, but the core solvent causes the inner surface of the hollow fiber to coagulate into a thin, dense, defect-free layer.
