Sealing PUL?

[mamalara]

I have a bunch of homemade aio dipes that have a 1mil pul outer. The pul seems to soak moisture right through. We didn't do any "sealing" before using these. Any suggestions? I've heard something about drying them on hot. Let me know what you think... thanks!

Right after you sew a diaper with PUL, before you *use* it (I can never resist just trying it on...) you need to wash it in hot water, and dry it in the dryer on high. That makes the PUL just *slightly* fluid, and it reseals the holes where you sewed it. It really takes 2 or 3 washes and machine-drys before it's totally "done".

If it's wicking right *through* the fabric, what kind of PUL are you using? Is it poly knit PUL or is it a cotton woven print PUL? The second kind will tend to wick because of the absorbent material on the outside. Making the inner with microfleece or suedecloth (or another synthetic wicking material) and making the legs roll **out** will help a little bit, it keeps the cotton out of contact with the wetness.

Two more questions: what are you using as absorbent layers, and how many? If you don't have enough absorbent material, your DC might just be wetting more than the PUL can hold. And if you have enough, the 1mil might not be enough, and you could make "sandwich" PUL by ironing two pieces together with the "shiny" sides touching (make sure to use a press cloth). The fabulous, bulletproof Bummis Super Whisper Wrap is made from sandwich PUL

HTH!

What is a press cloth? A cloth between the iron and the PUL?

Exactly You use a press cloth when you are ironing things with pile (like velvet) or things that can't take the direct heat from the iron (synthetics will melt and stick to the iron). You can buy press cloths, but I normally just use a white cotton plain woven dish towel (you don't want something with a textured weave).

I posted earlier but I don't see it on the replies...
I was basically asking if this would work with a PUL diaper pail liner I made that wicks at the seams, onto the cloth edging I sewed onto the outside. Won't the shiny sides 'melt' together, or onto the drier walls? Just want to check before trying anything out.

Thanks!!

Sorry it's taken me so long to respond! I have a new baby, born Oct. 30, and a toddler to keep up with, and it's new to me! It's great though, of course! I have a lot of diapers going on right now, so I'm glad to use this forum as a resource.

Our diapers are Sew Darling pattern, made with 2 layers of flannel for the body, and polyknit pul 1mil as an outer layer. We did a quick-dry soaker made of 2 layers of inner microfiber towel, plus 3 layers of flannel. The newborn little guy soaks through these more often than my 2 yr old. Should I add another layer of microfiber on the underneath of the soaker? It would not be touching the skin. We used polyester/cotton blend thread.

They're not a total disaster, just leaking through the pul around the edges and velcro enough to be annoying... We've only washed and dried (hot) twice so far. Maybe they'll improve with time... here's hoping!

Let me know what you think! THanks!

The polyester/cotton blend thread is what's making it wick. I had the same problem when I first started sewing diapers. You need 100% Polyester thread when sewing PUL, fleece, or wool, otherwise it will wick. GO BUY SOME before you make any more diapers!!!!!!! I hope that helps!

Will the washer/dryer method work if you had to reseal holes from a seam you had to unpick??

[kbstanley3]

Yep! Done it quite a few times, actually. You might have to run it through more than once, but it'll work!

You can try spraying the trouble areas with waterproofing if nothing else works. (On the outside of the diaper). Then, after it dries, dry it on high in the dryer.
