PVC Coated Fabric products can be waterproof on both sides, and the four sides are 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, this PVC Coated Fabric How to detect the density? In this regard, the PVC Coated Fabric manufacturer gave the following suggestions:
Indirect test method: After analyzing the fabric weave and the number of weaves circulating warp, multiply it by the number of weaving cycles in 10 cm, and the product obtained is the warp (weft) yarn density. This method is suitable for high density and special yarn A few small regularly organized fabrics.
Direct counting method: It is done by means of a cloth mirror or a fabric density analysis mirror. It should be noted that when counting the number of yarns, the starting point is the center between the two yarns.
In short, the size of the density will directly affect the appearance, feel, thickness, strength, flexural resistance, air permeability, wear resistance and thermal performance of the physical and mechanical indicators of PVC Coated Fabric. Therefore, you must pay attention to it when purchasing.
