Tarpaulin manufacturers explain the detection of tarpaulin density

     The tarpaulin product can be waterproof on both sides. The four sides of the tarpaulin are heat-sealed by single-folding heat sealing. The rope part is mainly used for fixing along the edge, and its application range is also very wide. Then, the density of this tarpaulin How should it be tested? The density will directly affect the physical and mechanical indicators of the plastic tarpaulin, such as appearance, feel, thickness, strength, flexural resistance, air permeability, abrasion resistance, and warmth retention. Therefore, you must pay attention to it when purchasing.

     The indirect test method is to analyze the fabric structure and the number of weaves circulating warp yarns, multiply by the number of weaves circulating in 10 cm, and the product obtained is the warp (weft) yarn density. This method is suitable for high density and yarn characteristics. Small regularly organized fabric. The direct counting method is accomplished 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 used as the starting point.

      When buying tarpaulin products, the quality is what we should care about. The important feature of tarpaulin is waterproof, so we can try to pour a small amount of water on the surface of the product. If the water does not penetrate into the tarpaulin, then this The quality of this product is relatively good. The density of the tarpaulin must be one of the important factors. The method of product identification is very simple, that is, to check the latitude and longitude of the product. The denser the product, the better the quality of the product.

      Secondly, we have to pay attention to the roughness of the product surface. In the selection process, we can feel the roughness and softness of the product by hand to distinguish the quality. If we want to buy good tarpaulins, we must not be cheap. Although the quality of such products is not decisively related to the price, quality often occupies a certain proportion of the product price. Generally speaking, if the price is relatively high for the same area, the quality of the product is better.
