Why Can Raincoats Be Waterproof? How To Clean Raincoats

Raincoat can be waterproof and rainproof, which is actually related to the design of raincoat material. Many people may knead their raincoats directly after using them and put them aside without cleaning or storing them. They can take them out and wear them when they need them. In fact, it is easy to shorten the service life of raincoat. I found some ways to clean raincoats for you.
Why raincoats can be waterproof
The raindrops on it will quickly gather into a small droplet and then flow away. This non-wetting phenomenon is the reason why raincoats are waterproof. Because the attraction of rubber molecules to water molecules is far less than that between water molecules, water molecules prefer to get together and roll down the raincoat surface. At the same time, there are many small holes in the cloth for making raincoats, but because the rain does not soak the rubber, it is difficult for water molecules to pass through the raincoat cloth through these small holes, so these small holes can not prevent the air molecules, which ensures the breathability of raincoats.
The raincoat is mainly made of PVC/PVC, nylon plus PVC, waterproof and moisture permeable cloth, oxford cloth and polytetrafluoroethylene (PTFE).
How to clean the raincoat
After using the raincoat, you can gently wipe off the water on it with a towel, and then hang the raincoat wholesale to dry. Do not expose the raincoat to the sun. After the raincoat is dried, you can fold it up and put it in a cool and dry place for ventilation and storage. The raincoat should not contact with strong corrosive liquid, which is easy to damage the rainproof layer of the raincoat, so remember.
Do not rub the raincoat when cleaning it, which will separate the PVC and nylon cloth, and cause air to penetrate and blister.
