Why are composite fabrics also called waterproof and breathable fabrics?

Composite fabrics are made by combining two or more fabrics. In fact, composite fabrics are not necessarily waterproof and breathable. This is a misunderstanding of the market. Strictly speaking, waterproof and breathable fabrics are made by combining a waterproof and breathable membrane (there are many types of membranes, such as PU, TPU, PTFE membranes, etc.), which can then be called waterproof and breathable fabrics. Breathable fabrics. Strictly speaking, waterproof and breathable materials are needed. In fact, without pressure, they cannot breathe; otherwise, they will not be able to windproof.

Waterproof and breathable fabrics are a new type of textile fabric. They are made from a composite of polymer waterproof and breathable materials (PTFE or TPU membranes) and fabrics. The main functions of waterproof and breathable fabrics are: waterproof, breathable, insulating, windproof, and warm. From a production process perspective, the technical requirements for waterproof and breathable fabrics are far higher than for waterproof fabrics; at the same time, in terms of quality, waterproof and breathable fabrics are more waterproof in terms of durability.
