Fiber Management

The fiber inside our Prism membrane separators is very valuable. It’s also really difficult to manufacture perfectly. Since the late 1970s, we’ve learned more and more about what to do and what NOT to do in the fiber spinning process. One thing that always helps, is to manage the fiber through measurements.

Our Spin Line Operators take fiber samples from the spin lines and measure dimensions under the microscope to see if they are within the passing range.  They can also see if the fiber is nonconcentric, which means that the hollow hole is off centered. They look for macro-voids, which are gaps, bubbles, or large pores in the fiber that cause a disruption in the permeation behavior. When abnormalities in the fiber are identified, we can focus on resolving the issue to ensure that only the highest quality of fiber makes it into the final membrane product.
