A Drop Stitch Fabric is one of the most important components of an inflatable paddle board. It is responsible for giving the board its shape and strength. This material is woven in a unique way to provide an incredibly strong and lightweight core that can be used in a variety of water environments. Woven Drop Stitch Core

The process of creating a drop stitch fabric is a complex one. First, two pieces of knitted polyester base fabric are sewn together using thousands of fine thread lengths. Then, a layer of neoprene or thermoplastic urethane is applied to the top and bottom of the fabric. This layer is then bonded to the other layers of the drop stitch fabric with wide seam tape for a bombproof, airtight seal. The result is a super strong, ultralight, and durable fabric that can be inflated to rock-hard rigidity.

Woven Drop Stitch technology is the latest development in the production of high-quality inflatables. It is superior to traditional knitted drop stitch material as it offers less give and higher stiffness, reflex, and rigidity. Woven drop stitch also uses fewer polyester threads per square centimeter for a lighter product that is easier to carry.

While the advantages of a woven drop-stitch material are obvious, there is still debate in the industry regarding the optimal thickness of a woven drop stitch fabric for optimum performance. This is mainly due to shear forces that appear during bending stress on the drop stitch fabric. Attempts to increase the bending stiffness by increasing the drop stitch fabric thickness or adding more layers of fabric is not ideal as it will lead to a reduction in performance and increased weight.

This article explores the bending response of a typical inflated drop-stitch panel by combining experimental results with a nonlinear beam finite element analysis. The model predicts the load-deflection behavior of the panel prior to wrinkling and at large deflections, allowing comparison between predicted and experimental data for orthotropic panel skin material properties.

Inflatable boats, rescue raft seating (inflated), structural membranes, inflatable screens, paddle boards, and gymnastics flooring are just a few of the many products manufactured from a revolutionary, patented woven drop-stitch material called “double wall” fabric. This unique construction process, which is referred to as “drop stitch”, consists of two parallel sheets of fabric held together by thousands of interlocking threads that are strong enough to keep the top and bottom of the fabric separated and parallel when stretched to their maximum. Unlike traditional knitting, which requires thicker yarn threads that are soft and stretchy, the double-wall drop stitch fabric is made from thinner, more rigid polyester fibers that are extremely resilient and stiff. This allows for the manufacturing of products that are far more advanced than traditional inflatables and provides a new level of performance that is unmatched in the nautical industry.
