Fabrics: mostly polyester-spun fabrics. The market is generally 210T polyester spinning and 190T polyester spinning. The quality is based on its thickness and warp and weft density. The technical specifications of waterproof fabrics are based on the degree of waterproofing. There are also manufacturers to enhance the appearance, feel, coated with silica gel on the foreign account, it looks like a translucent feeling, more importantly, such tents will be lighter.
Waterproof is only applied AC or PU. Usually only for children or game books.
Waterproof 300MM is generally used for beach accounts/shade accounts or cotton cloths for drought and rain. 800MM-1200MM is used for regular simple camping tents.
Waterproof 1500MM-2000MM is used to compare mid-range tents and needs to travel for many days.
Waterproof 3000MM or above is generally a professional tent, which has been treated with high temperature/cold resistance.
Bottom material: PE is generally the most common, and its quality depends mainly on its thickness and warp and weft density. It is better to use high-grade oxford fabrics, and the waterproof treatment should be at least 1500MM.
The inner fabric is generally breathable nylon or breathable cotton. Quality depends mainly on its density.
The rainproof performance of the outer tent fabric, this indicator is still calculated by how many mm of water column per square centimeter.
The general tents are rainproof above 1500mm water column, which can prevent moderate to heavy rain; individual reaches 3000-4000mm, which can prevent continuous heavy rain.
The high-quality rain-proof tarpaulin not only has high rainproof index, but also has a wide adhesive strip at the joint of the awning to prevent water from seeping at the seam.
Although the outer tent has a high rainproof index, ventilation is a problem. Even if there is no rainy sunny night, afterwards, the inside of the account will be covered with water droplets, especially on the wet ground such as grass. If you accumulate more, you will also drop into the internal account. Relatively speaking, the external accounts with low rain-proof indicators have less water in the inner area than rain-proof.
This is the water vapor that the occupants breathe out in the tent, and the water on the ground gathers on the inner surface of the tarpaulin. Because the outside account is rainproof, the rain outside can't get in, and the water vapor inside can't get out. So when you get up in the morning, avoid hitting the tent with force, be careful that there will be "light rain" inside.
However, there are several top-level tents, and the outer accounts are made of waterproof and breathable materials such as GORE-TEX and BANTEX, which can solve this problem relatively well, but the price is very expensive. Support skeleton
There are four common support skeletons (commonly known as tent poles):
1. Steel pipe: Also known as high-frequency welded pipe, it is mainly used in large tents such as military tents and disaster relief tents. The surface is sprayed or galvanized. There are round pipes and square pipes. The pipe diameter is generally 19~50mm. Etc., the wall thickness ranges from 0.8 to 3 mm.
2, elastic just: This type is generally a children's account or a beach game account.
3, fiberglass rod: There are a series of 6.9/7.9/8.5/9.5/11/12.5. The thicker the rigidity, the stronger the softness. Therefore, whether the choice of the fiber tube bracket is reasonable or not depends on the size of the ground and the proportion of the height. It is easy to break when it is too thick or too thin. For example: 210*210*130 is a classic size. The tube is generally 7.9 or 8.5. 4. The aluminum alloy frame is relatively high-grade. It is also difficult to test according to the alloy ratio. Generally, the original curve of the original bracket is the first. Calculated and then thermoformed. The characteristic is that the light carrying convenience is mainly not easy to fold, but the quality is not easy to bend and deform.
