Synthetic fibers are scientifically made to improve upon naturally occurring fibers. Most synthetic fibers
are petroleum based. Synthetic fibers include: acrylic, aramid, carbon, microfiber, nylon, olefin, polyester, polyethylene,
spandex, tencel, vinalon, and zylon.
Synthetic fibers have been gaining on cotton for world market share; however,
cotton still makes up over 39% of the world fiber market. Since synthetic fibers are mostly petroleum based their price and
competitiveness depends on the price of oil.
