I thought I would pass this along to clear up some myth's about pul. Hope it helps with some that have questions about pul. This was posted by Linda of Happy Heiny's....<br><br><br>
"There are many "myths" that continue to float around the wahm/diapering community and unfortunately these myths sometimes cause more problems then what they help to fix.<br>
Procare and PUL are 2 different materials made by 2 different companies.<br>
PUL was originally made for the medical community and in fact is still made for the medical community. It is made to be autoclaved.<br>
The spec sheets that are specific for PUL sent out by the company, specifically state that you may not only dry the PUL but you can also iron the PUL, non-shiny side only.<br>
The best way to describe the PUL itself is that it is made up of tiny rods like this: I these rods are standing and fill all the nooks and crannies of the fabric, both poly and cotton. Over time, with normal washing the rods fall down like this: --- When they fall down they are no longer in all of the nooks which can cause wicking through the fabric.<br>
This can happen on both cotton and poly. The reason it is most noticeable on cotton is because poly naturally repels water, so although it will eventually wick through the fabric holes, it will not wick as fast as the cotton does.<br>
By drying the PUL you are heating it, the way it was meant to be originally treated, and you are in effect re-generating the rods, making them stand back up. This is why when you have a good diaper (non-repelling etc) that is suddenly wicking through the diaper and you dry it a couple times it is all of a sudden all better.<br>
PUL itself has no fabric content and the laminate "should" not wear out. This depends on the fabric and how the fabric behaves, but has nothing to do with the PUL itself.<br>
Cotton PUL fabrics wear faster than solid PUL fabrics just because of the fabric, not the PUL. Just like your favorite t-shirt, it will wear faster than your most dreaded poly pants that never seem to die. It is the difference between a natural fabric vs. man-made. When someone buys a cotton print, they are typically washing it 3 times a week, more than you would wash a favorite t-shirt, so it only makes sense as to why the fabric itself would begin to fail, develop holes etc. It also depends on detergents, other additives to the wash, water content, and how often it is actually washed. Your solid PUL should last forever unless it gets a run.<br>
The 1000 washes, is basically a CYA type of thing. It is kind of like bummis who says that their diapers need to be replaced every 3 months. They will most likely last much longer, but to CYA they recommend something different.<br>
There have been issues with dried PUL and it melting. The products who have had this problem have had PUL that was purchased outside of the US and there were other factors, it was not the same as our PUL purchased in the states and 99% of your PUL products. The issues with bubbling and de-laminating of PUL has nothing to do with the PUL but instead with changes in the fabric and/or dye content. Certain dye colors will almost always lead to eventual de-laminating. If this happens the diaper will work just fine, unless the PUL is snagged. Bubbling usually happens from the fabric not being completely shrunk(is that a word).<br>
PLEASE, PLEASE, PLEASE IF YOU ARE A WAHM, STOP THE INSANITY, STOP TELLING THEM NOT TO DRY THEIR PUL. This is counter-productive to your product, will cause you problems in the long run, and continues to fuel inaccuracies with in the community which leads to confusion for the customers.<br>
Pro-care, is very different than PUL and is made with similar materials used in fire retardants. There are some who disagree, if you use this, please know it is a very different product.<br>
Your PUL should outlast your diaper, if your diaper is wicking through the diaper, throw it in the dryer on high heat. Also, always wash on high heat, this decreases stink in fleece and hemp, and also works in keeping your PUL functioning 100%.<br>
All of my suggestions are made based on experience and talking with people who have been around since the early wahm days, and in having long talks with the manufacturers. Not just the reps who will tell you what they think, but the actual manufacturers.<br>
Finally, both 1 mil and 2 mil PUL are breathable. 1 mil is more breathable than 2 mil, but they are both breathable.<br>
HTH<br>

interesting.<br><br>
i know for one of my wetbags i bought as a second, it was returned since the original buyer said it leaked. the wahm said she couldn't get it to leak but if it leaked to just throw it in the dyer on high heat for 20 minutes and that would seal the leak. i did it just to make sure it didn't leak and never had an issue for over 1 year and counting. i guess my story adds to linda's comments.

It isn't so much falling into the myth that drying PUL hurts it, but knowing the nature of diapering vs some of the other uses for the fabrics will naturally have different results then what they may be tested for. (prints which result in fading and bubbling over time, elastic edges rubbed against while tumbling and agitating in the wash will wear holes in the fabric side of the PUL after too much wash/dry)<br><br>
My prefold needs a 45 minute dry cycle... my pocket needs maybe 10-15. I don't think it is insane to warn against cooking a diaper. It would fall under that CYA thing mentioned earlier in the post <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">

I use PUL and I love PUL but I very highly doubt that either 1 or 2 mil are breathable.<br><br>
Since we're talking PUL myths, can I add something?<br><br>
Bleach will not hurt PUL.<br>
2 mil is NOT better than 1 mil, it's the other way around<br>
DWR does NOT wash off after 12 washes.

I always remove my PUL covers very soon after I start the dryer. They don't wear down that way! <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">

PUL is <i>laminated</i>. How on earth could that be breathable?<br><br>
ETA: The other info was fascinating though. I throw my PUL in the dryer all the time. Mostly out of laziness... and when I'm doing the laundry it's usually a hurry-it-up situation anyway.

Yeaaa! I am SO glad this finally got posted..I shoulda done it LONG ago ( when Linda first took the time to type all of this wonderful info). PLEASE PLEASE, do NOT tell your customers, or the people you pass diapers onto, to hang their PUL to dry. Tell them to dry em the quick, easy and effective way.. IN THE DRYER ON HOT!!!<br><br><img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/thumb.gif" style="border:0px solid;" title="thumbs up">

Isn't the easiest way to tell if PUL is breathable is to breathe on it?? <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/confused.gif" style="border:0px solid;" title="Confused">: I picked up one of my FB's, folded the fleece back, put it around my mouth and held it tight... then blew. No matter how hard I blew I couldn't get any air to pass through (i.e. I couldn't feel any air on my hand on the other side... and also gave myself a headache :LOL ). This was not the case with even my thickest fitted (though the fabric itself circulates air) and I could still feel my breath on my hand on the other side of the diaper. I love my FB's and the fleece is breathable along with any gaps that may occur in the diaper, but from what I can tell the PUL alone does not breathe at all.<br><br>
Ok, and that completes my very unscientific experiment. :LOL

I don't think that would tell you for sure. It might tell you that something is less easily breathable than other things, but air could be dispersed when going through the PUL such that a forceful wind wouldn't make it through.

I dry my diapers on the line, not because I'm afraid of ruining them, but because it saves energy.<br><br>
So am I actually HURTING the PUL by drying it on the line? It will still function OK, right?<br><br>
I have some Fuzzi Bunz that wick through the PUL,should I throw them in the dryer?<br><br>
And lastly...<br><br><div style="margin:20px;margin-top:5px;">

I think bottom line is you can dry them how ever the heck you want, but drying them on hot in the dryer WILL make them wear faster no matter what anyone wants to believe :LOL!!!!

Kay, DWR is durable water repellant.<br><br>
NickNJulesMom - What I mean by 1 mil is better than 2 mil, is 1 mil is better when you're talking PUL for diaper making purposes. The diapers are MUCH softer, never rough and stiff, and they don't make that uberly annoying crinkling sound.

Ok thanks for clarifying that. 2 mil is thicker lamination that is the difference, and I really don't have a problem w/ crinkling, rough or stiff pul with any of my 2 mil. But I have been thinking of trying 1 mil is that what you use in your diapers?

But you do need to dry them in the dryer on hot to keep the pul functioning properly, not every wash but once a week or so.
