{{Olefin fibers}}

Olefin fibers that are synthesized only by unsaturated aliphatic monomers called olefin. The largest of these fibers are polypropylene fibers made by the polymerization of propylene. Since the polymer contains asymmetric carbon atoms the result is steric polymers (Natta Polymers). The Italian Natta was the first who created this polymer. Also, ethylene can be polymerized to fiber polymer. With high orientation of molecular chains one can produce fibers with durable strength.

Olefin fibers are used for many things except clothing purposes; it is used for packing of various kinds - both as weave and yarn. It is also used as cordage at sea since it floats. Olefin fibers cannot be dyed in the usual way without the need of special preparation. Therefore, it is common that these fibers are dyed by spinning, ie. Dye is added into the melted polymer.

==Environmental Facts – olefin fibers==

'''Emissions into air:''' In the production of ethylene and propylene and when the polymerization takes place there are some existing air emissions, but tries to recycle these items have been made.

'''Emissions into water:''' The fibers are spun melted and therefore provide no direct emissions to water. For some fiber grades lubricants are used in the spinning process which must then be washed out afterwards.

'''Energy usage'''?!
