Description: PUL is a polyester/polyurethane laminated knit fabric with a laminate thickness of 1.00 mil. This fabric is waterproof, durable and has a slight crossgrain stretch. This product can be used in making diapers, changing mattress covers and applications that require ...
You need to look after PU-coated fabric. The PU coating itself can absorb water molecules-that's how it 'breathes' after all. The technical term for this behaviour is that the coating is 'hydrophilic' (water loving).But as a result, water can act as a very slow solvent to polyurethane.hat is, a coating of silicone polyer has been applied to both sides. Well, fair enough, but there is a huge difference in the result between PU and silicone coating. The PU coating sits on the surface of the fabric, but the silicone polymer goes right in.
