Olefin fiber is a synthetic fiber made from a polyolefin, such as polypropylene or polyethylene. It is used in wallpaper, carpeting, ropes, and vehicle interiors.Olefin's advantages are its strength, colourfastness and comfort, its resistance to staining, mildew, abrasion, sunlight and its good bulk and cover.t is used in wallpaper, carpeting, ropes, and vehicle interiors.

Now we're going to talk about taking monomers with double bonds, and using them to make polymers with double bonds in the backbone chain. We call these polymers polyalkenamers. One way to make polyalkenamers to use a nifty reaction called olefin metathesis. Olefin is an old word, kind of like betwixt or forsooth. An olefin is the same thing as an alkene, that is a molecule with a carbon-carbon double bond. Olefin metathesis is of course a reaction involving olefins. Two olefins, to be exact. And here's what they do: the double bond carbons change partners, to form two new olefins, just like in the little picture here:
