Double-Wall Fabric Welding

Weldable Dropstitch Material

Double-wall or drop stitch fabric is becoming increasingly popular with applications such as inflatables, paddle boards, gym mats, and more.

What Is Double-Wall / Dropstitch?

It’s a coated nylon joined by thousands of vertical fibers that are uniform in size. The distance of fibers can vary in sizes and the panels are covered with polymer coatings to form an air tight cavity. When double-wall (dropstitch) fabric is welded into the desired shape and pressurized with air, it is transformed into a strong, hard surface.

Double-wall fabric benefits:

Double-wall fabrics can be used to manufacture inflatable products that are lightweight and easy to transport yet are rigid and structurally stable.

  • Created using a 3D weaving process
  • Has a smooth surface structure
  • 85% more tensile strength than knitted drop-stitch fabric
  • Favorable adhesion during the welding process
Products produced using double-wall fabrics include:
  • Paddle Boards
  • Inflatable Boat Bottoms
  • Athletic Mats
  • Water Mats
  • Air Tracks
  • Inflatable Dock Systems
  • Cushions to Secure Cargo
  • Work Tents
  • Inflatable Molds
  • Absorbtion Cushions
  • and more… 
With the characteristics of this material combined with the welding process, the possibilities are endless. Is double-wall fabric right for your applications
How is double-wall / dropstitch material cut?

Double-wall fabric is recommended to be cut with an ultrasonic cutter. An ultrasonic cutter allows. patterns to be precisely cut; producing clean, straight edges when welding.

  • First you will align the top and bottom panels for the fibers to match up
  • Mark your pattern where you want to cut
  • Clamp your material together and cut the pattern with Miller Weldmaster's Ultrasonic Cutter
  • Start welding your sidewall fabric. We recommend our T300 Extreme Curve  Double-Wall for welding double-wall / dropstitch material
Ultrasonic Cutter for welding dropstitch or double-wall material
