The Cradle to Cradle Certification story at MechoSystems is one of great innovation, perseverance, and—ultimately—success. Twitchell, in support of our shared vision, became a fabulous partner. Together we pioneered the replacement of a PVC-coated, polyester yarn, with a technical yarn. EcoVeil uses a TPO (thermoplastic olefin) extrusion over a polyolefin core yarn (replacing the polyester core yarn). There were many challenges along the way. With our combined efforts, we eventually reached the ideal hand (softness) of the shadecloth, tested its flame retardancy and manipulated its color fastness and its ability to weld into a shadecloth, and to then hang flat. Each one of these issues required revolutionary work. In the end, we succeeded and were awarded a Cradle to Cradle Certification, now certified Silver. The flame-retardant chemistry remains a challenge to further improve EcoVeil. But the concept made it possible to have a PVC-free coated yarn that minimizes yellow and red chemicals, and can be recycled.
