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. Drop stitch fabric is a great material that we can use to achieve our many imaginations. Basically, we can use it to produce a Stand-up Paddleboard and sports mattress. Go further we can use it to make a wall of SPA, inflate tent, the roof of the float tank, and lifesaving mattress, etc. Even you can make a boat with 100% drop stitch material. Ten thousand of 100% high strength threads between the top layer and bottom layer make the material be of high performance of strength. With different processing, it can be inflated up to 30 PSI while recommended pressure is 15 PSI.
DROP STITCH DOUBLE WALL TYPES:
Warp knit (tricot) and woven base faric are all made from polyester DTY yarns but from different machines. Warp knit is the most widely used on the market due to the high production speed. Woven base fabric production speed is only 30% of warp-knitting but it is light weight and robust, so usually used for luxury products.
|Warp knit（Tricot）||5-30cm||Most widly used|
PVC WARP-KNIT DOUBLE WALL FABRICS:
Warp knitted (tricot) dropstitch is the most widly used. With ten thousands of high strength threads between top layer and bottom layer, this material is high performance of strength and suitable for all applications.
PVC WOVEN DOUBLE WALL FABRICS:
Woven drop stitch is mainly used for luxury paddle boards and floating platforms. It offers reduced weight and increased tensile strength due to the way the internal fibres are woven.
|DLT-6812W||12cm||2200gsm||Gym mat, Floating docks|
TPU WOVEN DOUBLE WALL FABRICS:
TPU material is widly used for food and medical equipment. Drop-stitch fabrics with TPU film are designed for inflatable structures with high airtightness and ageing properties, along with minimum weight. This is a innovation of high-end material for dropstitch products.
