Fabrics with this type of finishing can preserve their waterproof and oil proof properties even after multiple washing.
Fabrics with petroleum and oil proof finishing, which is resistant to multiple washing, easily preserve their properties after multiple washing.
This film polyurethane microcellular "breathing" covering is white (or coloured) film, which can let through water molecules only in vapour state but not water drops. Water resistance is 350 – 700 mm of water column. Vapour permeability (breathing properties) are 5.0-10.0 mg/cm2/hour.
Fabrics with this type of finishing can preserve their waterproof properties even after washing. The fabric does not moisten and protects against contact of water with the skin. The fabric is vapour permeable (facilitates perspiration), but does not leave moisture on the surface.
