PVC Tarpaulin is a relatively common material product in industrial and agricultural production. With the increasing demand, especially waterproof PVC Tarpaulin plays an important role in freight logistics, industrial land, farms, etc. And according to the PVC Tarpaulin manufacturer, when using PVC Tarpaulin, there are a few things that need to be understood:

  1. Density parameter, the calculation unit of PVC Tarpaulin fabric density is in metric system, which refers to the number of warp and weft yarns arranged within 10cm. The density directly affects the physical and mechanical indicators of the fabric, such as the appearance, feel, thickness, flexural resistance, air permeability, abrasion resistance, and warmth retention of the fabric. It is also related to the cost of the product and the size of the production efficiency.

  2. Through the indirect test method, it is possible to test the fabric with large density and regular weave with small yarn characteristics, analyze the fabric weave and the number of weaving loops (the number of weaving wefts), and then multiply it by the number of weaving loops in 10cm. The product of is the warp (weft) yarn density.

  3. The direct measurement method is used to complete the fabric density analysis mirror or fabric density analysis mirror. The length of the scale of the fabric density analysis mirror is 5cm. Below the analysis lens, a long glass sheet is engraved with a red line to analyze the density of the fabric. When moving the lens, align the red line on the glass sheet and the red line on the scale between two yarns at the same time, using this as the starting point, move the lens while counting the number of yarns until the 5cm scale line is this. The number of output yarns multiplied by 2 is the density value of 10cm fabric.

  4. Fine PVC Tarpaulin warp and weft yarns are used to make, labor protection clothing and supplies. After dyeing, it can also be used as fabrics for shoes, travel bags, backpacks, etc. In addition, there are rubber PVC Tarpaulin, fire and radiation shielding PVC Tarpaulin, and PVC Tarpaulin for paper machines.
