An ongoing partnership that is working to explore the benefits of combining two natural based fibers - Merino Wool and NatureWorks fibers - has been announced by The Woolmark Company and Cargill Dow LLC. Cargill Dow, a US based joint venture, is responsible for the conception and launch of NatureWorks fibers - commercially viable materials bridge the gap between natural fibers and synthetics. The resins, made from annually renewable resources such as corn, wheat and cassava, can be used in a range of fiber, textile and nonwoven fabric applications.
