Textile polypropylene fibers: fundamentals
1999Polypropylene (PP) fibers contain, according to ISO 2076, minimally an 85% portion of macromolecular polypropylene chains and maximally 15% of another fiber-forming polymer, the content of nonfiber-forming substance being unlimited. Of the stereoregular isomers, only isotactic PP is used for fiber preparation.

Microporous polypropylene films and fibers
1999Recently, microporous polypropylene (PP) materials (sheets, films and hollow fibers) have gained acceptance in various fields of separation technology. Usually, these microporous materials are prepared by using uniaxial or biaxial stretching of adequate ‘preforms’. Some examples of processing routes are: 1.

Natural fiber/polypropylene composites
1999There are ecological and economical reasons in favor of the use of natural fibers as reinforcing fibers for plastics. A lower price, better recyclability, hygienic harmlessness and a carbon dioxide neutral combustion are the advantages of natural fibers compared to glass fibers (GF).
