Material Description
Fabric: Most of them are polyester spun fabrics, and the general ones on the market are 210T polyester spun and 190T polyester spun. The quality is based on its thickness and warp and weft density, and the technical indicators of waterproof fabrics are based on the degree of waterproofing. Some manufacturers also apply silicone on the outer tent to enhance its appearance and feel, giving it a semi transparent feel. More importantly, this type of tent is lighter.
Waterproofing only involves applying AC or PU on the surface. Usually only used for children or gaming accounts.
Waterproof 300mm is generally used for beach tents/sunshades or cotton tents used for drought and low rain. Waterproof 800mm-1200mm is used for regular simple camping tents.
Waterproof 1500mm-2000mm for mid-range tents that require multiple days of travel.
Waterproof tents above 3000mm are generally professional tents that have been treated with high temperature/cold resistance technologies.
Bottom material: PE is commonly used, and the quality mainly depends on its thickness and latitude and longitude density. Oxford fabric should be used for better and more high-end materials, and the waterproof treatment should be at least 1500mm or more.
The internal fabric is generally breathable nylon or breathable cotton. Quality mainly depends on its density.
The rainproof performance of the external tent canopy is still calculated based on the number of millimeters of water column it can withstand per square centimeter.
Generally, tents have a waterproof height of 1500mm or above, which can prevent moderate to heavy rain; Some reach 3000-4000mm, which can prevent continuous rainstorm.
High quality rainproof tarpaulin not only has high rainproof indicators, but also has wide and thick adhesive strips at the joints of the tarpaulin to prevent water seepage at the joints.
Although the rain resistance index of the outer tent canopy is high, breathability is a problem. Even on a sunny night without rain, after sleeping, the outside and inside of the tent will still be covered with water droplets and particles, especially when setting up tents on damp ground such as grasslands. Accumulating too much will still drip into the internal account. Relatively speaking, external tents with low rainproof indicators have less water on the inner surface than those with high rainproof indicators.
These are the water vapor exhaled by residents inside the tent, and the water droplets accumulated by the ground vapor on the inside surface of the tent. Due to the rain protection of the external tent, the rainwater cannot come in from outside, and the water vapor inside cannot go out. So when you wake up in the morning, avoid forcefully shaking the tent and be careful that it may rain lightly inside.
However, there are several top tier tents that use waterproof and breathable materials such as GORE-TEX and BANTEX on the exterior, which can effectively solve this problem, but the price is surprisingly expensive. Supporting skeleton
