Olefin is a category of performance fiber made from polyolefin. It is one of the most popular synthetic fiber families that includes polypropylene and polyethylene. Olefin can be manufactured in filament yarns with different structures, which can be used as a breathable fiber or for heat retaining purposes. Olefin is hydrophobic and lipophilic, which means it can only be solution-dyed and printed with oil-based paints. Untreated olefin can be easily degraded by light. With added flame retardants and lightfastness agents, olefin is applicable for outdoor upholstery use. The melting point is relatively lower than other thermoplastic fibers, which may limit finishing options. The fabric resists abrasion, water-based stains, and diluted bleach, which makes it ideal for active wear, indoor upholstery, area rugs, and doormats. It is often used as a backing for commercial carpet as well. The common trademarks of olefin fabric include Tyvek and Tervira.
