Falling in love with a way of life seems to have become the consensus of many people today. Among those who truly realize this abstract concept, campers can be described as pillars, and they firmly implement the lifestyle of going camping all year round. For campers, apart from their family members and friends, the best companions are tents. A tent that shelters from the wind and rain like a house and faithfully provides shelter for the camper is the camper's home outdoors, so functionality is critical, such as waterproofing. Is my camping tent waterproof? Can it prevent light rain or heavy rain? This is probably the question that haunts campers the most. Today, Friday Camp will talk about this question.

Where does the waterproofness of camping tents come from?

The waterproofness of camping tents is mainly completed by the outer tent, and the outer tent has a double-layer structure:

1. High-density, tear-resistant, lightweight fabric;

2. On the outside of the fabric, apply a layer of water-repellent coating to make the fabric have a lotus leaf effect, that is, the water droplets roll down the fabric, and

The inside of the fabric will not be entered. In this way, the camping tent is waterproof.

What are the types of waterproof coatings for camping tents?

Commonly used camping tent waterproof coatings can be divided into the following categories:

1. PVC coating

The waterproof effect is good, but it will become brittle and hard in severely cold weather, so it should be used in high-temperature seasons.

2. PU coating

After coating, the fabric feels plump and elastic, the surface has a film feel, and the effect of preventing (rain) water is good, and it will not become brittle and hard even in severely cold weather.

3. Silicone coating

It has good temperature resistance, waterproof effect, and is lightweight, of course, the price will be more expensive.

4. PTFE film

It is a film with waterproof, windproof, and breathable functions, which can be attached to the fabric to form a new windproof and waterproof fabric (like a jacket), breathable, waterproof, lightweight, wear-resistant, and durable, but the price is quite expensive, compared with general camping tents useless.

How to determine the water-resistance of a camping tent

The waterproof (rain) water function of camping tents can be measured by the waterproof index. The waterproof index of camping tents is also the water pressure resistance, which refers to the hydrostatic pressure on the unit area of the camping tent fabric. The waterproof index is obtained through testing.

1. Test method

During the test, first, clamp a sample of the camping tent fabric to a circular kit with a diameter of about seven centimeters. The lower part of the kit is a system that can pressurize the water. The water is pressurized by an electric method. Use this to determine how much water pressure is needed to get water through the camping tent fabric. As the pressure continued to increase, the first drop passed through the tent sample, but this pressure was not the final result. The pressure value at this time was the final result until the third drop of water broke through the tent fabric sample.

2. Interpretation of indicators

If the pressure value is 1200MM, it means that this camping tent has a waterproof capacity of 1200MM, that is, a water column pressure of 1.2 meters high can penetrate the water through the camping tent fabric. Moreover, this indicator will be marked on the tag of the camping tent. Can you guys look at your own camping tent to see what the waterproof index is?

Seeing this, do you guys know more about the waterproofness of camping tents? When camping, you are not afraid even if it rains a little, and you can enjoy the beauty of nature in the rain!
