Cotton
Cotton is one of the most widely grown natural fibers in the world, harvested from the seed pods of the cotton plant. It has been used in clothing for thousands of years across every major civilization.
Where it comes from
Cotton plants are grown primarily in the United States, India, China, and Brazil. The fiber is harvested from the boll — the protective case around the seeds — and spun into yarn.
Properties
Microplastics
Cotton is a natural fiber. It does not contain synthetic polymers and does not shed microplastic particles during washing. When cotton fibers break down — in the wash or at end of life — they biodegrade.
