Back to fabric types

PUL is a waterproof fabric.  It is used as the outer part of your nappies, covers and diapers.

Pul can also be used as a hidden layer underneath fabrics.

PUL is not the fabric, but the laminate that is applied to the fabric. 

People refer to the whole piece of fabric (fabric+laminate) as PUL.

Polyurethane laminate:

Frequently referred to by it’s abbreviated name PUL (Said as either P-U-L, or Pull). PUL is a soft clear coating of polyurethane that is applied to the back of fabrics resulting in a product that is both waterproof and has a small amount of breathability, making it a perfect choice for nappy making.

PUL comes in either 1MIL, or 2MIL, the MIL referring to the thickness of the laminate. Most fabrics are laminated with the 2MIL as it withstands frequent washing and is longer lasting. The laminate is applied to either cotton fabric or polyester fabric.
