In the specific product design or use, the following properties of Stripe PVC Tarpaulin should be considered.
Stripe PVC Tarpaulin must consider its breathability, especially military tent tarpaulin. The influencing factors of breathability include base fabric structure, density, material, type of waterproof finishing agent, resin adhesion, etc. As the amount of resin adhesion increases, the air permeability of Stripe PVC 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
Stripe PVC Tarpaulin has to withstand 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 energy saving. Despite these external forces, they are still required to maintain their original shape and not easily deform. This requires Stripe PVC Tarpaulin to have a higher tensile strength, and there should not be too much difference in tensile strength in the warp and weft directions.
3. Elongation and dimensional stability
Stripe PVC Tarpaulin for roof tents and Stripe PVC Tarpaulin for large tents are often used under tension. Stripe PVC Tarpaulin should not stretch too much, and its dimensional stability is determined by the creep characteristics of the material.
4. Tearing strength
Stripe PVC Tarpaulin damage is mainly caused by tearing, so tear strength is an important indicator of Stripe PVC Tarpaulin. Tear strength is related to whether Stripe PVC 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. Water resistance
Water resistance is an important feature of Stripe PVC Tarpaulin. Through dipping and finishing, the vinyl chloride fat is filled in the gaps of the fabric to form a coating film. If the amount of resin adhesion per unit area exceeds a certain level, water resistance is not a problem. If the coating film is thin, the coating film is easy to break when it is bent, rubbed or the surface is abraded, which may cause water accumulation.
6. Flame retardancy
From the safety of use, it is required that Stripe PVC Tarpaulin has better 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.
In addition to the above performance requirements, Stripe PVC Tarpaulin also requires superior cold resistance, heat resistance, tarpaulin, creep resistance, repeated fatigue resistance, abrasion resistance, and bending resistance.
