How waterproof & breathable films work to keep you dry and comfortable?
To create a waterproof garment that is also breathable, allowing the wearer’s perspiration vapor to escape, a garment manufacturer will typically employ a textile composite. This composite is made by a fabric laminator who sandwiches a layer of Peak Brand waterproof-breathable film between two layers of fabric.
The top fabric is normally the final outer layer of the garment, the bottom an optional inner lining material. Peak brand films are available in a variety of polyurethanes and copolyesters, depending on the hardness, elongation, and moisture vapor transmission rate (MVTR) required for the garment and its end-use. Each is a solid, monolithic, hydrophilic membrane with no continuous pores through the film. Rather, moisture passes through by absorption into the membrane on the inside face and is “transported” to the outside by solid state diffusion where it evaporates upon exposure to the atmosphere.
At the same time, the Peak TPU film creates a waterproof barrier that physically repels
rain or other liquids from passing through to the inside of the garment. The combination is a functional piece of high-performance apparel that keeps the wearer dry and comfortable.
