or alkene Any unsaturated hydrocarbon containing one or more pairs of carbon atoms linked by a double bond (see covalent bond, saturation). Olefins may be classified by whether the double bond is in a ring (cyclic) or a chain (acyclic, or aliphatic) or by the number of double bonds (monoolefin, diolefin, etc.). Rare in nature, olefins are obtained by the cracking of petroleum fractions at high temperatures. The simplest ones (ethylene, propylene, butylene, butadiene, and isoprene) are the basis of the petrochemicals industry. They react by adding other chemical agents at the double bond to form derivatives or polymers
This fiber is also called polypropylene, and is extremely popular in Berbers and level loops Olefin carpets are highly stain, static, mold, and mildew resistant They can be used for indoor or outdoor carpets, including outdoor turf Their resistance to matting and crushing are not as good as a nylon fiber
A manufactured fiber characterized by its light weight, high strength, and abrasion resistance Olefin is also good at transporting moisture, creating a wicking action End-uses include activewear apparel, rope, indoor-outdoor carpets, lawn furniture, and upholstery
