摘要
A process for determining the polymer concentration in a spinning dope solution involves measuring the propagation velocity of ultrasonic sound in the solution. The process prevents fluctuations in the polymer concentration as much as possible, and is therefore highly suitable for application in the production of fibers with consistent properties. An ultrasonic device used in the process is easier to clean, install, and calibrate than other presently commercially available devices.
