Description

A manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85% by weight of ethylene, propylene or other olefin units, except amorphous (noncrystalline) polyolefins qualifying as a rubber fiber (Federal Trade Commission definition). The process for making polyethylene fibers was developed in Germany by Karl Ziegler in 1954. In 1957, Giulio Natta (Montecatini, Italy) produced polypropylene fibers. Olefin fibers are lightweight, smooth and white with a slightly waxy feel. They are resistant to wear, creases, acids, alkalis, moisture, fungi and insects. Olefin fibers slowly degrade in sunlight and can be stained by oils. Olefin fibers are used to make protective clothing, carpeting, artificial grass, upholstery fabrics, and stay-dry clothing.
