Summary: The service life of tarpaulin is generally 6-12 years, and good tarpaulin should meet the following basic performance

The service life of tarpaulin is generally 6-12 years, and good tarpaulin should meet the following basic performance indicators. These several performance indicators also determine the lifespan of the tarpaulin.

1、 Water resistance of tarpaulin

Water resistance is an important characteristic of tarpaulins. Through impregnation finishing, vinyl chloride resin is filled into the gaps of the fabric tissue to form a coating film. If the resin adhesion per unit area exceeds a certain level, water resistance is not a problem. If the coating is thin and subjected to bending, soft rubbing, or surface wear, the coating is prone to cracking, which may cause mud and water. (Crosslinking agent used for PE tarpaulin)

2、 Flame retardancy of tarpaulin

Starting from the safety of use, it is required that the tarpaulin has good flame retardancy. Flame retardancy can be obtained by selecting flame-retardant fibers and flame-retardant base fabrics. It can also be achieved by adding flame retardants to the coating agent. (Crosslinking agent used for PE tarpaulin)

3、 Tensional strength of tarpaulin

Tarpaulins must withstand various tensions during use, such as tension when tightened during fixation; During use, it is subject 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, which requires the tarpaulin to have high tensile strength and should not have too much difference in tensile strength in the warp and weft directions.

4、 Tarpaulin tearing strength

The damage of tarpaulin is mainly caused by tearing, so tearing strength is a relatively important indicator of tarpaulin. The tear strength is related to whether the tarpaulin will break due to the effect of flying foreign objects or expand outwards after forming holes due to certain reasons, forming large structural cracks. So, when the tension is high, both high tensile strength and high tear strength are required for the canopy fabric. (Crosslinking agent used for PE tarpaulin)

5、 Breathability of tarpaulin

When considering the breathability of tarpaulins, such as military tent fabrics, factors that affect breathability include the fabric structure, density, material, type of waterproof finishing agent, and resin adhesion. (Crosslinking agent used for PE tarpaulin)

6、 Tenpy stretch and dimensional stability

Large tents are often used under tension. The elongation of fabric should not be too large, and its dimensional stability is determined by the creep characteristics of the material. (Crosslinking agent used for PE tarpaulin)

In addition to the above performance requirements, tarpaulins also require good cold resistance, heat resistance, tarpaulin, creep resistance, repeated fatigue resistance, wear resistance, and bending and bending resistance.
