Laser cut is a technology that uses a laser to cut materials and is typically used for industrial manufacturing applications. The laser used in laser cutting is very hot and therefore able to melt plastics/polyester.
Since there are fabrics consisting of different amounts of polyester, I researched whether laser cutting could be used for gluing fabrics.
On top, 6 different flat fabrics and on the bottom-side 6 different hairy fabrics were being used. In the end this technology was proven to be usable in gluing two fabrics. However, how well the fabrics glued, depends on the amount of polyester in both fabrics, how thick the fabrics are together and how much space there is in between the two layers.
