The characteristics of the tarpaulin
- Sep 30, 2017 -

What are the performance characteristics of the tarpaulin sold on the market now?

1, breathability: tarpaulin must consider its permeability, especially the military tents cloth, breathability of the factors such as the end of cloth tissue, density, materials, waterproof finishing agent type, resin adhesion and so on. With the increase in resin adhesion, the permeability of the tarpaulin decreased. Of course this is related to the finishing agent used. Generally have the permeability of the canopy most of the paraffin or acrylic resin finishing the cotton, vinylon, lacquer and other short-cut fabric products.

2, the tensile strength: tarpaulins in the use of all the tension to bear, such as fixed when the tension to be tension: the use of the process to be affected by the wind, rain, the province and other additional force. Despite these external forces, they are still required to maintain the original shape, not easily deformed, which requires the tarpaulin has a high tensile strength, and should not have too much latitude and longitude to the tensile strength difference. Especially as inflatable building with a large tent tension strength is extremely important. Generally its base fabric with high-strength polyester, vinylon and other long fiber fabric by the vinyl chloride resin, chlorosulfonylated polyethylene resin waterproof finishing. The strength of the product is mainly determined by the strength of the fibrous material and the density of the fabric.

3, elongated skin and dimensional stability: as the roof canopy and large tent, is often used under tension. Fabric elongation should not be too large, its dimensional stability is determined by the creep characteristics of the material.

4, tear strength: tarpaulins mainly caused by tearing, so tear strength is an important indicator of tarpaulin. Tear strength is related to whether the tarpaulin will rupture due to the role of flying objects or for some reason in the formation of holes after the expansion of the surrounding, the formation of large structures crack. So when the tension is big. Both require a high tensile strength of the canopy cloth, but also requires it to have a high tear strength.

5, water resistance: water resistance is an important feature of tarpaulin, through the impregnation finishing, the vinyl chloride filling the fabric of the gap in the fabric to form a coating. If the amount of resin per unit area exceeds a certain degree of above, water resistance is not a problem. If the coating is thin, by bending, soft rub or surface wear, the coating is easy to break, it may cause muddy water.

6, flame retardant: from the use of the safety of the mountain, the tarpaulin has a good flame retardant. Flame retardancy can be obtained by using flame retardant fibers and flame retardant base cloth, or by flame retardant in the coating agent. The addition of flame retardant has a direct relationship with the flame retardant effect.
