Abstract:
Processes for forming cosmetically appealing edges on laminated fabric structures are described. The methods involve a laser cutting process that includes in-process melting of polymer material within the laminated fabric so as to coat fibers of the laminated fabric. The resultant cut laminated fabric has a cosmetic edge that has no exposed fibers. The laser cutting and melting can be performed in a single laser cutting operation, making it well suited for integration into manufacturing product lines.
