Polypropylene fiber

Polypropylene (PP for short) belongs to the polyolefin family and is the most widely used thermoplastic in Europe in terms of volume. It owes this to its flexible areas of application, relatively low raw material costs and good processability. Its insensitivity to hydrolytic degradation, good strength values and easy handling also make PP a very attractive starting material for fiber production. The polypropylene fibres offered by EFS are produced using the melt spinning process, in which the fibres are created from the melt in the capillaries of spinnerets and stabilized by stretching processes and thermal conditioning.

Pros and cons
Polypropylene fiber Properties


  • High strength and high elongation capacity
  • Hydrophobic and therefore highly resistant to mold
  • Alkali resistant
  • Low density (specific weight)


  • UV-resistant only when stabilizers are used

Polypropylene fiber
Manufacturing process

Polypropylene is produced using organometallic catalyzed polymerization. Either the Ziegler-Natta catalysts, named after their inventors, or the somewhat more recent metallocene catalysts are used. Depending on the catalyst used and the required property profile, isotactic or syndiotactic polypropylene can be produced. The good and simple processability of polypropylene allows a variety of possibilities for fiber production. Various melt spinning techniques are mainly used. In addition, fibers based on the film-to-fiber or meltblow process are also available.
