What is the working principle of GORE-TEX fabric

GORE-TEX fabric is a high-performance fabric widely used in outdoor sports equipment, and its working principle is mainly based on the following aspects:

Waterproof principle

The core of GORE-TEX fabric is a layer of polytetrafluoroethylene (PTFE) film. PTFE has a tight molecular structure and extremely low surface energy, making it difficult for water molecules to penetrate.
At the same time, the diameter of the micropores on the film is much smaller than that of water droplets, making it impossible for external rainwater, snow water, etc. to enter the interior of the fabric through these micropores, thereby achieving excellent waterproof performance

Breathable principle

Although the micropores of PTFE film are small, their pore size is larger than the diameter of water vapor molecules. The water vapor emitted by the human body can diffuse outward through these micropores, making the wearer feel comfortable and avoiding stuffiness caused by sweat accumulation. This feature allows GORE-TEX fabric to maintain good breathability while being waterproof

Sliding down from the summit feels like soaring in the clouds, every turn is an ultimate tribute to the beauty of nature, making people feel refreshed and forget about worldly troubles

Windproof principle

The overall structure of PTFE film and fabric can effectively block the flow of air, forming a windproof barrier. Whether it is a gentle breeze or a strong wind, it is difficult to penetrate the fabric, reducing the heat loss caused by air convection and helping the wearer stay warm in cold environments.
