In this March 24, 2017 photo, Dr. Luke Haverhals, founder and CEO of Natural Fiber  Welding In Peoria, Ill., examines yarn which is being run through solvents that alter the outer structure of the material. The research at Natural Fiber is working to alter the properties of natural fibers like cotton in order to increase their strength and anti-microbial properties while still keeping some of the original desirable qualities. Since manufactured fibers like polyester that contain plastic microfibers are largely petroleum based, the research could lead to a more sustainable product and less plastic pollution.
