Drop stitch fabric is a type of fabric that is used to make inflatable products such as inflatable stand-up paddle boards, inflatable kayaks, inflatable boats, and inflatable pool toys.
Drop stitch fabric is made by sandwiching a layer of high-strength polyester yarn between two layers of PVC (polyvinyl chloride) material. The yarn is then sewn through the PVC layers in a grid pattern, creating a series of small air pockets. When the fabric is inflated, the air pockets expand and the yarn stretches, creating a stiff and stable surface.
The key feature of drop stitch fabric is that it is extremely durable and can withstand high pressure. It can be inflated to high-pressure levels, which gives it the ability to maintain its shape and rigidity even when it is fully inflated.
Drop stitch fabric also has good resistance to UV and abrasions, which makes it suitable for outdoor use. It is also resistant to punctures and leaks and can be easily repaired if it is damaged.
Drop stitch fabric is widely used to make inflatable watercraft, such as inflatable stand-up paddle boards and inflatable kayaks, which are becoming increasingly popular for recreational use. They are lightweight, easy to transport, and can be quickly inflated and deflated for storage and transport.
