Does PUL need to be dried in a dryer to work?

I have purchased some used diapers, but I'm also planning on getting a few new ones.  I'm planning on washing my diapers by hand (with a stick washer thing) and line or rack drying, but I read somewhere that to make PUL completely waterproof you have to dry it in the dryer a few times to seal the fibers.  Do any of you know if that's true or not?

It is best to throw PUL in the dryer every so often to reseal it where it's been stitched.

Usually, a hot dry is recommended to "seal" the PUL after sewing (to seal around the stitch holes), or occasionally after use to re-seal. I generally line dry mine with no problems.
