PVC coated drop stitch double wall fabric for crash test unit

PVC tarpaulin is a high strength polyester canvas as the base cloth, coated polyvinyl chloride (PVC) paste resin with growth agent (synthetic plant ester), anti-mildew agent, anti-aging agent, antistatic agent and other chemical additives, through high temperature plasticization. Waterproof, mildew resistant, cold resistant, aging resistant, anti-static and other properties; And the breaking strength, tear elongation, tear strength is much better than traditional tarpaulin. Its wide range of use, the use of strength, color diversity, the surface of the special treatment to play the role of anti-skid, is an international popular waterproof fabric, and the width is very large, up to 2 meters wide, the use of available thermal joint splicing, without sewing pinhole leakage worry, is the mainstream products in the modern tarpaulin market.

Product Parameter Product Details

   Drop stitch fabric construction is what allows an inflatable SUP to maintain its shape when it is inflated to high pressure. Without drop-stitch, the board would bulge out in the middle like an over-inflated air mattress. Using tens of thousands of tough polyester threads, drop stitch fabric lets us build inflatables with flat surfaces that can be inflated to rock-hard rigidity. You get hard-shell performance along with the easy transportation and storage of an inflatable. Drop stitch fabric SUP boards use the toughest drop-stitch materials in the industry. Sidewalls use two PVC layers specifically manufactured for superior air holding. Unlike typical PVC tarpaulin, the specialized sidewall material features internal fibers coated in liquid PVC before incorporation with the outer PVC layer, making the layers more durable and resilient than ever before.

   DWF(Double Wall Fabric), which it is with 3D hollow structure. By using 3D weaving technology, the two layers of base fabric are connected together with the pile yarns. Due to the different ways of the pile yarns, the surface shape can be a pattern like wavy (W shape), starr y, linear, and other surface shapes can be customized such as X shapes. Since each pile yarn thread has got the same length which define the maximum distance between the two base fabrics, DWF keeping of the desired shape of the hollow body - a dimensionally-stable surface, smooth and excellent flexibility.
