Polypropylene monofilaments combine low density with a high tenacity and good abrasion resistance and are finding some application in ropes and netting. 

Mitsubishi Corp. has developed a Rovalpolypropylene fiber with good antistatic, anticorrosive, and color properties. It can be woven into carpet for computer rooms. Courtaulds Corp. invented an electrically conductive polypropylene fiber that has excellent chemical resistance. Unlike surface-treated conductive fibers, this polypropylene fiber provides uniform electrical conductivity across its filament. These conductive fibers are now offered in multifilament and monofilament forms at 12 and 18 tex. An antistatic polypropylene fiber of fine denier was also invented by researchers at East China University of Science and Technology, Shanghai, China. It can be used in domestic polypropylene carpets. With hypothermal agglomerates, it can be prepared in partially oriented polypropylene filament yarn for use in antipollution, antistatic applications such as work clothes for operating personnel in oil, chemical, and electronics industries [230,231].

As the name implies, single filaments are extruded the molten filaments are cooled and solidified in a water bath and then drawn. Typically, monofilaments are fairly large, being on the order of 250 dpf. Rope and twine are produced by twisting bundles of monofilament together. Polypropylene rope and twine are strong and moisture resistant, making them very useful in marine applications. 

A comparatively recent development in the technique of monofilament production is based on extrusion of film which is subsequently slit and then processed in the same way as the conventional monofilaments. Tapes produced from slit film are used in many applications ranging from strapping, ropes and twines, to woven sacks and carpet backing. The main material here is polypropylene with some of the lighter tapes made in high density polyethylene. 

Monofilament fabrics are woven from extmded synthetic filaments produced in diameters from 30 jm to 2-3mm.These fabrics have become important as filter media in a broad range of industries and applications. Because of their corrosion resistance, ability to withstand vibration fatigue, uniformity and economy to use, they have replaced a number of other types of media. The chemical and food processing industries, industrial hydraulics, medical, automotive and appliance maikets are major users of monofilament fabrics. These fabrics are available in a range of polymer filaments including nylon, polyester, polypropylene and fluorocarbon materials, in aperture ratings from 5-5000 pm.
