What is PUL?
PUL, or Polyurethane Laminate, is the water proof outer layer on most modern cloth diapers. PUL is Water-proof, flexible and durable. It is created by bonding a plastic layer to the fabric you see as the outer part of your cloth diaper.
What Exactly is Delaminaion and Why Does it Occur?
Delamination is when the waterproof laminate begins to pull away from the fabric. Cloth diapers are washed and worn MANY times, and, just like regular clothing, over time it is normal for cloth diapers parts to deteriorate, including PUL. Having a large stash is the #1 way to combat wear and tear on your diapers, its the difference of washing daily compared to a couple times a week. (you wouldn't was a shirt daily and expect it to hold up) Washing or drying in high heat are also common causes of delamination. SoftBums recommends washing in temperatures no higher then 140 degrees and to avoid the sanitize cycle as the water will get too hot. It is also recommended to line dry as often as possible or if you must use a dryer never to turn up past medium, aside from the initial 10-15 in the dryer on hot to seal the seams.
