What is PUL Fabric?

So... What's polyurethane laminate - apart from a mouthful!?

Polyurethane laminate is often abbreviated to PUL fabric.

PUL is special... It's a waterproof AND breathable fabric!

Why is this important? Well, it means if you make waterproof items of clothing your body heat has a better chance of escaping into the atmosphere! Heat escapes THROUGH the fabric - so you "glow" less!


Composition of PUL Fabric

PUL has 2 sides... one side is a polyester knit - so has a slight stretch - which is great for clothing... The other side has a laminate coating applied. It’s slippery and shiny - this is the waterproof bit.

Smooth and Knitted side of PUL fabric
  • PUL is soft & flexible
  • It doesn't really crease
  • It air dries in super quick time
  • It's safe - there's no lead, phthalates or BPA

Is there a right or wrong side?

We ALWAYS get asked this. Is there a right side to ensure “waterproof-ness”. There isn’t really, it's personal preference. The fabric will be waterproof no matter which side you choose... so go with the look that pleases you most!

That said, for aesthetic & comfort reasons I usually use knit side as the “right” side most often - it's more comfy if your project will be close to the skin.

Tips For Sewing With PUL Fabric

✂️ Needle: Use a stretch needle

✂️ Stitch Length: Use 3mm stitch length

✂️ Machine Foot: A walking foot is helpful. If your machine foot is sticking then you can apply a bit of Scotch Magic Tape to the base of your normal machine foot

✂️ Thread Type: Polyester thread is recommended to match the fabric composition

✂️ Sealing sewing holes: When you sew your needle will leave tiny holes behind in the laminate layer which MAY affect the waterproof effectiveness of your garment.

These holes are easily resealed ... either

✂️ pop your garment in the tumble dryer on low for 20 minutes

✂️ if you are using our White PUL it's weldable so just iron it (using a pressing cloth!) and the holes will seal!

❤️ A special note regarding our own brand of white PUL … we get this manufactured ourselves here in the UK & it has some very special properties:

☔ It's waterproof YET breathable

☔ It's medical grade ?

☔ It's weldable giving you a completely sealed seam (Look! No leaks!)

☔ It's fungistatic which - apart from being a brilliant word - means it inhibits the growth of fungi & bacteria ?

☔ It is double laminated - whaaaat's that?! It means it lasts longer & is less likely to delaminate over time as it's washed loads

☔ It's fire retardant
