Testing method of tarpaulin density

The tarpaulin product can be waterproof on both sides, and the four sides of the tarpaulin can be heat-sealed by single-fold heat sealing. The rope part is mainly fixed along the edge, and its application range is also very wide. Then, the density of this tarpaulin How should it be detected? In this regard, tarpaulin manufacturers have given the following suggestions: Indirect test method: after analyzing the fabric structure and the number of weave loops, multiply the number of weave loops in 10 cm, and the product obtained is the warp (weft) Yarn density, this method is suitable for fabrics with high density and small yarn characteristics. Direct measurement method: It is completed by means of a cloth mirror or a fabric density analysis mirror. It should be noted that when counting the number of yarns, the center between the two yarns should be taken as the starting point. In short, the size of the density will directly affect the physical and mechanical indicators such as the appearance, feel, thickness, strength, folding resistance, air permeability, wear resistance and thermal insulation performance of plastic tarpaulins. Therefore, it must be paid attention to when purchasing.
