Question from Donna
Hi, Debra,
Here’s one more question on the safety of PUL in diaper covers. What if the PUL is completely enclosed in polyester, as in Bummis Super Whisper Wraps? Is it still harmful to my baby? Thanks so much!!
Debra’s Answer
Polyester doesn’t act as a vapor barrier. The fabric would block skin exposure to PUL, but it wouldn’t block vapors that could be inhaled or absorbed through the skin.
In addition, polyester fabrics are treated with a formaldehyde resin that lessens with repeated washings but never completely washes out.
I’d stick with the natural fibers.
