An outdoor tent is a movable building. The skeleton is composed of tent poles and camp ropes and fixed; the outside of the skeleton is covered with an outdoor tent, which can block the line of sight, wind, and rain. Therefore, the outdoor tent needs to have the following characteristics to better block the outdoor environment, so PVC tarpaulin
has become an excellent choice.
The characteristics of outdoor tents must be equipped
Tarpaulins must consider their breathability, especially military tent fabrics. The influencing factors of breathability include the structure of the base fabric, density, material, type of waterproof finishing agent, and resin adhesion. As the amount of resin adhesion increases, the air permeability of the tarpaulin decreases. Of course, this is related to the finishing agent used. Generally, most air-permeable tents are made of cotton, vinylon, lacquer and other short-woven fabrics finished with paraffin wax or acrylonitrile resin.
2. Tensile strength
The tarpaulin must bear various tensions during use. For example, when it is fixed, it will be tensioned: during use, it will be subjected to additional forces such as wind, rain, and snow. Despite these external forces, they are still required to maintain their original shape and not easily deform. This requires the tarp to have a higher tensile strength, and there should not be too much difference in tensile strength in the warp and weft directions.
In particular, the tensile strength of large tents for inflatable buildings is extremely important. Generally, the base fabric is made of high-strength polyester, vinylon, and other long-fiber fabrics. It is waterproof and finished with vinyl chloride resin and chlorosulfonated polyethylene resin. The strength of the product is mainly determined by the strength of the fiber material and the density of the fabric.
3. Dimensional stability
As eaves tents and large tents, they are often used under tension. The elongation of the fabric should not be too large, and its dimensional stability is determined by the creep characteristics of the material.
4. Tear strength
Tarpaulin damage is mainly caused by tearing, so tear strength is an important indicator of tarpaulin. The tear strength is related to whether the tarpaulin will break due to the action of flying foreign objects or expand to the surroundings after forming a hole for some reason, forming a large structural crack. Therefore, when the tension is high. It is required not only to have high tensile strength but also to have high tear strength.
5. Flame retardancy
From the perspective of safety in use, the tarpaulin is required to have good flame retardancy. Flame retardancy can be obtained by selecting flame retardant fiber and flame retardant base fabric. It can also be achieved by adding flame retardant to the coating agent. The amount of flame retardant added is directly related to the flame retardant effect.
First of all, PVC tarpaulin is also called polyvinyl chloride cloth. The characteristics of PVC are waterproof, anti-aging, anti-static, and tear-resistant. Outdoor inflatable tents happen to meet these characteristics, so the material is very suitable for making tents.
Secondly, from the appearance of PVC tarpaulin, it has good color and bright reflection, one side is flat and smooth, and the other side has some granular objects, indicating that the resin composition is appropriate and the temperature is suitable for high temperature and severely cold areas.
The surface has no pinholes and has good anti-aging performance, which is why the inflatable tent made of PVC material has a long service life. This is why it is more expensive than ordinary canvas and Oxford cloth.
Its waterproof performance is very good, due to its good glue quality, so it can adapt to the bad weather of outdoor heavy rainfall. This kind of fabric feels very soft. Although it feels normal in thickness, the thickness has actually reached the required thickness. It just feels very soft because of the high resin content and good processing technology, but it does not feel rough.
It is also a trend to choose PVC tarpaulin for outdoor tents. Now the environmental protection department has very high requirements for environmental quality and restricts production to production enterprises to reduce pollutant emissions.
This has also brought new challenges to many tent manufacturers. Studies have shown that this PVC material is made of high-quality environmentally friendly resin, with a smooth surface, bright colors, waterproof, fireproof, anti-corrosion, mildew, cold resistance, high-temperature resistance, UV resistance, anti-aging, and other properties.
