Raincoats are sewn from waterproof fabrics such as tape, tarpaulin, and plastic film, including the latest PTFE waterproof and breathable laminate fabrics. Raincoat waterproof principle Modern raincoats have more and more materials and styles, but no matter how you change it, the raincoat has a property that has never changed. That is, the raindrops will quickly gather into a small waterdrop and then flow away. It is the reason that the raincoat is waterproof.
It is a kind of non-wetting phenomenon that rainwater falls on the surface of raincoats. Because rubber molecules are much less attractive to water molecules than water molecules, water molecules prefer to get together and roll down the raincoat. At the same time, there are many small holes in the fabric for making raincoats, but because the rain does not infiltrate the rubber, it is difficult for water molecules to pass through the small rain holes through the raincoat fabric, and these small holes do not play a role in the air molecules, which ensures The breathability of the raincoat.
What kind of material is the raincoat good?
Raincoats are rain-proof clothes made of waterproof fabric. Waterproof fabrics for raincoats include tape, tarpaulin and plastic film. Modern raincoat waterproof fabrics focus on breathability, such as special nylon and Gore-Tex. Breathable raincoats help people to wear moisture from the raincoat when they are wearing rain, increasing comfort.
