i have the modal sheets from bb&b. i've used them as my only sheets since september. iwash them once every week adn half or so. i have regular sealy spring mattress. i wash on delicate cycle with cold water and dry on delicate (ie low heat) i have had very little if any pilling. the pillow cases are worse than the sheets. the only problem i've had is i got a toe nail stuck on one part that pulled it up a bit but it hasn't worsened.
i use a pretty regule detergent (costco) and no softener or static sheets and i don't iron them. pretty much they're in great shape. only thing i've noticed is some darker spots that seems to be from long term sweat stains. overall i've been very happy with them and will buy again.
don't know if that helps but, hey, mabye...
