When designing the tarpaulin, its performance must be taken into account. According to relevant professionals, the performance to be considered in this process mainly includes:
1. Air permeability: the air permeability of the tarpaulin must be considered, especially the military tarpaulin. The influencing factors of air permeability include the fabric structure, density, material, type of waterproof finishing agent, resin adhesion, etc. With the increase of resin adhesion, the air permeability of the tarpaulin decreased.
2. Tensile strength: the tarpaulin shall bear various tensions during use. For example, the tension during fixation shall be subject to tension. During use, the tarpaulin shall be subject to additional forces such as wind, rain and energy saving.
3. Tear strength: the damage of the tarpaulin is mainly caused by tearing, so the tear strength is an important indicator of the tarpaulin.
4. Extended skin and dimensional stability: it is often used under tension as roof canopy and large canopy. The elongation of fabric should not be too large, and its dimensional stability is determined by the creep characteristics of the material.
5. Flame retardancy: the tarpaulin is required to have good flame retardancy in terms of safety. Flame retardancy can be obtained by selecting flame retardant fiber and flame retardant base cloth.
6. Water resistance: water resistance is an important characteristic of tarpaulin. Through impregnation finishing, vinyl chloride resin is filled in the gap of fabric tissue to form a film.
