What performance should be provided when PVC fabric designing and using

1. Breathability

The air permeability of the pvc fabric needs to be considered during use. The factors affecting the air permeability include the structure of the base fabric, density, material, type of waterproof finishing agent, and amount of resin adhesion.

2. Tensile strength

The pvc fabric will withstand all kinds of tension when it is used, such as tension when it is fixed; it will be subjected to additional forces such as wind, rain, and snow during use. Despite these external forces, they are still required to maintain their original shape and not be easily deformed, which requires a higher tensile strength of the tarpaulin.

3. Tearing strength

The damage of the pvc fabric is mainly caused by tearing, so the tearing strength is an important indicator of the tarpaulin. The tear strength is related to whether the tarpaulin will be broken due to flying foreign objects or due to some reasons, it will spread to the surroundings after the formation of a hole to form a large structural tear. Therefore, when the tension is large. Not only the tarpaulin is required to have a high tensile strength, but also a high tear strength.

4. Water resistance

Water resistance is an important characteristic of tarpaulin. By dipping and finishing, the vinyl chloride resin is filled in the gaps of the fabric structure to form a coating film. If the amount of resin adhesion per unit area exceeds a certain level or more, water resistance is not a problem. If the coating film is thin, when it is bent, rubbed or the surface is worn, the coating film is easy to break, which may cause muddy water.

5. Flame retardancy

From the safety of use, the tarpaulin is required to have better flame retardancy. Flame retardancy can be obtained by selecting flame retardant fibers and flame retardant base fabric. It can also be achieved by adding flame retardant to the coating agent. The amount of flame retardant is directly related to the flame retardant effect.
