“For each product type, we had to disclose our ingredients and our suppliers had to disclose their ingredients for full transparency,” said Francis Mason, a senior research engineer at Lycra. “The products with material health certificates come from all six of our Lycra fibre sites.” 

Manufacturing takes place in Maydown, Ireland; Foshan, China; Tuas, Singapore; Monterrey, Mexico; Paulinia, Brazil; and Waynesboro, Virginia.

Jean Hegedus, sustainable business development director for Lycra, said: “Our goal was to make a step-change toward safe, fully optimised chemistries, so we looked to certify a broad range of products used across multiple fabric types and applications.”
