Which performance characteristics judge the quality of tarpaulin?

Tarpaulin is widely used in many aspects of daily life, but there are many tarpaulin manufacturers in the market, and the quality of each tarpaulin product is also very different. From which performance characteristics to judge the quality of tarpaulin? Air permeability: The air permeability of tarpaulins must be considered, especially for military tent fabrics. The factors affecting air permeability include base fabric organization, density, material, type of waterproof finishing agent, and resin adhesion. With the increase of resin adhesion, the air permeability of the tarpaulin decreased. Of course this depends on the finishing agent used. Generally, most of the tents with air permeability are made of cotton, vinylon, lacquer and other short fiber fabrics finished with paraffin or acrylic resin. Tensile strength: The tarpaulin must be subjected to various tensions during use, such as tension when it is fixed: it must be subjected to additional forces such as wind, rain, and province during use. Despite these external forces, they are still required to maintain their original shape and not easily deformed. Especially the tensile strength of large tents used as inflatable buildings is extremely important! Dimensional stability: As canopies and large tents, it is often used under tension. The elongation of the fabric should not be too large, and its dimensional stability is determined by the creep characteristics of the material. Rainproof cloth is widely used in vehicles, ships, factories and mines to cover goods, field travel and other purposes. Tear strength: The breakage of the tarpaulin is mainly caused by tearing, so the tear strength is an important indicator of the tarpaulin. The tear strength is related to whether the tarpaulin will break due to the action of flying foreign objects or expand to the surrounding after forming holes for some reasons, forming large structural cracks. So, when the tension is high. Both high tensile strength and relatively high tear strength are required for the tarpaulin! Water resistance: Water resistance is an important feature of tarpaulins. By dipping and finishing, the vinyl chloride fat is filled in the gaps of the fabric to form a coating film. If the resin adhesion amount per unit area exceeds one of these levels, water resistance is not a problem. If the film is thin, it is prone to cracking when subjected to bending, rubbing or surface abrasion (a basic type of component failure), which can cause water leakage! Anti-flammability: From the safety of use, the tarpaulin is required to have good flame retardancy. Flame retardant 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! The above characteristics affect the quality and practicability of the tarpaulin itself, and it is necessary to distinguish effectively during the purchase process.
