Tackle twill is a form of appliqué that is commonly used in the garment industry. In addition to a single-layer process, multiple layers of tackle twill can be stacked to provide a 3-D effect. Tackle twill is made from nylon or polyester (PET) woven fibers with an adhesive backing. Tackle twill readily absorbs the energy from both the 9.3 and 10.6 micron CO₂ lasers. The material that is directly in the path of the laser beam is rapidly vaporized creating a clean, smooth cut.
