A synthetic raw material from which textile fibres and yarns are manufactured. It is made up of saturated hydrocarbons with one of the carbon atoms carrying a methyl side group.
Polypropene is prepared from propene gases.
Polypropene fibres have good strength but only moderate elasticity and are therefore not suitable for carpets subjected to intense traffic. It is one of the least expensive synthetic fibres and therefore particularly used in cheaper carpets. Polypropen is also known by the older name polypropylene. This last name is still the most common name among producers and consumers.
