Nowadays, with the improvement of people’s environmental awareness and the introduction of national environmental protection policies, many new environmentally friendly materials are emerging one after another, and Teflon waterproof and breathable membrane is one of them.
The development of completely waterproof and breathable fabrics (waterproof) began in the late 1970s. The current second generation products are completely waterproof and windproof and maintain good breathability.
However, garments made of this kind of fabric are not necessarily completely waterproof, mainly because of water seepage in seams or zippers. To ensure that the garment is completely waterproof, you need to glue all the seams (good garments use waterproof Pressing), which requires a lot of labor and cost, is one of the reasons why such clothes are so expensive.
The working principle of breathability can be divided into two types: micropores and hydrophilic groups. Teflon waterproof breathable membrane uses the former, because the minimum diameter of water droplets is about 20 microns, and the diameter of water vapor molecules is only 0.0004 There is a huge difference in diameter between the two. Water vapor can pass through the microporous membrane through the principle of diffusion. Liquid water or water droplets cannot pass through due to the surface tension of liquid water or water droplets, which prevents water penetration and makes it breathable. The membrane has a waterproof function.
