Re: Effective Fiber Sieving

The most obvious method is flotation or settling in a fluid.

say you've got a fluid moving smoothly upwards in an inverted cone; the
velocity decreases as height increases. A unique fiber diameter will be
suspended at each height (where the downwards gravitational force is
balanced by the upwards drag force.)

There are many variations on this theme.

The biggest practical problem is that the fibers must be separated so
they don't tangle. I can't imagine a method that can possibly work if
the fibers are tangled.
