Knowledge characteristics of raincoat fabrics, which is the best raincoat fabric? Raincoats are sewn from waterproof fabrics such as tape, tarpaulin, plastic film, including the latest Polytetrafluoroethylene (PTFE) waterproof breathable laminated fabrics. The principle of waterproofing of raincoats There are more and more materials and styles of modern raincoats, but no matter how they are changed, there is one property of raincoats that has never changed, that is, rainwater drops on it will quickly gather into small droplets and flow away. That’s why raincoats are waterproof.
Rain falling on the surface of the raincoat is a phenomenon of non-wetting, because the attraction of rubber molecules to water molecules is far less than the attraction between water molecules, and the water molecules prefer to gather together and roll down the surface of the raincoat. At the same time, there are many small holes in the fabric for making raincoats, but because rainwater does not infiltrate the rubber, it is difficult for water molecules to pass through the raincoat fabric through these small holes, and these small holes do not play a role in organizing the air molecules, which ensures that Breathability of raincoats.
