What is Olefin?
Basic Principles of Olefin Fiber Production — Olefin fibers (polypropylene and polyethylene) are products of the polymerization of propylene and ethylene gases. For the products to be of use as fibers, polymerization must be carried out under controlled conditions with special catalysts that give chains with few branches. Olefin fibers are characterized by their resistance to moisture and chemicals. Of the two, polypropylene is the more favored for general textile applications because of its higher melting point; and the use of polypropylene has progressed rapidly since its introduction. The fibers resist dyeing, so colored olefin fibers are produced by adding dye directly to the polymer prior to or during melt spinning. A range of characteristics can be imparted to olefin fibers with additives, variations in the polymer, and by use of different process conditions.

Olefin, also known as polypropylene or polyethylene, is a long-chain polymer synthetic fiber. It is created when ethylene and/or propylene gases are polymerized under very specific conditions. Olefin was first manufactured in the late 1950s, and has a myriad of applications in manufacturing, household products and clothing. Use of olefin has steadily increased since the 1960s, and continues to gain in popularity every year as new uses for this easy, durable material are found. Olefin is created when the polymers are melted to a liquid, then run through a machine called a spinneret, which forces the product into a long fiber through small holes. This fiber is then used to make the fabric, or the end product in which it will be used. Because olefin resists dyeing, any dye must be added during this melting process, instead of to the final fabric or product. It is highly favored due to its easy, inexpensive manufacturing process. Surprisingly, olefin is relatively environmentally “friendly
