The rainproof performance of camping tent mainly lies in the fabric. According to our years of work experience in Lohas Industrial Co LTd, several common fabrics are listed for your reference.
Technical specifications of waterproof fabrics are based on the degree of waterproofing.
Waterproof is only AC or PU coated. Generally only used for children or game accounts.
Waterproof 300MM is generally used for beach tents / shading tents or cotton tents for drought and rain
Waterproof 80MM-1200MM is used for conventional simple camping tents.
Waterproof 1500MM-2000MM is used to compare mid-range tents, which need to travel for many days.
Waterproof above 3000MM is generally a professional tent, which has been treated with high temperature / cold resistance technology.
Bottom material: Generally, PE is the most common. The quality depends on its thickness and density of warp and weft. It is better to use high-grade Oxford fabrics, and the waterproof treatment must be at least 1500MM.
The inner fabric is usually breathable nylon or cotton. Quality mainly depends on its density.
The rainproof performance of the outer tent cloth is still calculated based on how many mm of water column per square centimeter.
General tents are rain-proof above 1500mm water column, which can prevent moderate to heavy rain; some of them reach 3000-4000mm, which can prevent continuous heavy rain.
The high-quality rain-proof tarpaulin not only has high rain-proof index, but also has thick rubber strips at the joints of the awnings to prevent water seepage at the seams.
Although the outer tent cloth has a high rainproof index, ventilation is a problem. Even on a clear, rainless night, the inside of the outer tent will be covered with water droplets, especially when the tent is set up on wet ground such as grass. If it accumulates more, it will drip into the internal account. Relatively speaking, the external accounts with low rainproof indicators have less internal water than the rainproof ones.
This is the water vapor exhaled by the occupants in the camping tent. The water vapor on the ground gathered water droplets on the inner surface of the tarpaulin. Because the tent is rainproof, the rainwater outside can't come in, and the water vapor inside can't go out. So when you get up in the morning, avoid shaking the tent with force, be careful that there will be "light rain" inside.
