Abstract
A laser sensor based equipment was assembled for on-line measuring the fiber diameters during the polymer spinning. The analog signals come from laser sensor were detected by using a data acquisition instrument and transferred into digital ones, which were processed in time with Labview. In a typical experiment, the diameters of polypropylene fibers were tested under different spinning speed by means of that pre-calibrated on-line measurement equipment, and the testing results were compared with those obtained from the numerical simulation of spinning dynamics. It has been found the on-line diameter measurement could promise high-speed, highly reliable and flexible testing.
