Industrial Fabrics Joining Methods

​The type of project you are working on, where it will be used, and the expected lifespan of the final product all affect the type of joining method you should use. 

Seaming tape/glue 
 Seaming tape and glue both work by adding a layer of adhesive between the two layers of fabric to create a bond. Tape and glue are easy to apply, require no specialized equipment, and are low cost; however, bonds have a short lifespan and are not suited for use outside as they deteriorate quickly under the strain of the elements.

​Sewing/stitching 
 Sewing requires an industrial sewing machine capable of handling the thickness of material being used, as well as a skilled operator to ensure a precise and neat finished product. Resulting seams are more visible than heat welded or adhesive bonded seams. Seams are strong and can withstand exposure to the elements. 

Chemical welding 
 Chemical welding is similar in application to glue. However, instead of adding a layer of adhesive between the layers of fabric, the chemicals applied dissolve part of each layer to produce a stronger bond. The chemicals are easy to apply but can be dangerous and must be handled carefully to avoid injury. Safety precautions include gloves, safety glasses, and proper ventilation. Chemical welds are strong and can be used outdoors. 

Heat welding 
 Heat welding produces the strongest bond; with the correct application of heat and pressure welds are as strong as the material itself. Manual, automatic, and stationary machines are available. Some operator training is required to produce precise and neat welds but equipment operation is simple. Seams are extremely strong and can withstand prolonged exposure to the elements.
