Polypropylene fiber


A manufactured fiber made from the polymers or copolymers of polypropylene. In 1954, Giulio Natta (Milan Polytechnic, Italy) polymerized propylene and by 1957 polypropylene fibers were being commercially produced by Montecatini Societa Generale (Italy). Polypropylene fibers are lightweight, smooth and white with a slightly waxy feel. They are resistant to wear, crushing, acids, alkalis, moisture, fungi, and insects. Olefin fibers slowly degrade in sunlight and can be stained by oils. Polypropylene fibers are used to make rope, fishing nets, sewing threads, diaper covers, indoor-outdoor carpeting, artificial grass, upholstery fabrics, and stay-dry clothing. They are also used for geotextiles fabrics, pavement repair, roofing felts, and artificial ski slopes.
