I have spun milkweed seed fiber before, but I have not yet worked with fiber obtained from the plant. I purchased it from Conserving Threads and it came uncombed in a large cloud of fiber. I pulled out long strands to twine, knocking loose many tiny fibers. Combing or hackling the fiber first would remove most of the short bits.

The milkweed bast fiber is more course than the seed fiber, but it is also stronger.
