What are the fabrics of camping tents

The rain resistance of a camping tent lies mainly in the fabric. According to Xiaobian's several years of work experience in Zhengzhou Yongsheng tent factory, several common fabrics are listed for your reference.

The technical indicators of waterproof fabrics are subject to the degree of waterproofing.
Waterproofing is only the exterior coated with AC or PU. Generally, it is only used for children's or game books.
Waterproof 300mm is generally used for beach tents/shade tents or cotton tents for drought and little rain
Waterproof 80mm-1200mm is used for regular simple camping tents.
Waterproof 1500mm-2000mm is used for more mid-range tents, which require multi-day travel.
Waterproof more than 3000mm is generally a professional tent, which has been treated with high temperature/cold resistance and other technologies.

Bottom material: PE is generally the most common, and the quality mainly depends on its thickness and warp and weft density. Better and more high-end oxford fabrics, waterproof treatment should be at least 1500mm or more.
The inner fabric is generally breathable nylon or breathable cotton. The quality is mainly based on its density.
The rainproof performance of the outer tent cloth is still calculated by how many mm of water column per square centimeter it bears.
Generally, the tent is rainproof 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 rainproof tarpaulin not only has a high rainproof index, but also has a wide and thick adhesive strip at the junction of the tarpaulin seam to prevent water seepage at the seam.

Although the rain protection index of the outer tent cloth is high, ventilation is a problem. Even on a sunny night when there is no rain, the inside of the tent is covered with water droplets, especially on wet ground such as grass. If you accumulate more, it will drip into the inner account. Comparatively speaking, the outer tent with low rainproof indicators has less water inside than the one with high rainproof.
These are the water vapor exhaled by the occupants in the tent, and the steam from the ground collects water droplets on the inside of the tarpaulin. Because the outer tent is rainproof, the rainwater from the outside cannot come in, and the water vapor inside cannot get out. So when you wake up in the morning, avoid touching the tent too hard and be careful that it will rain "lightly".
