Manufacturing and characterization of nanoclay-modified polypropylene fibers

摘要

In this research project PP with 1 %, 2% and 3% nanoclay, and 0.75%, 1.5% and 2.25% PP-g-MA was spun to fibers using high process speeds. The following evaluations revealed that the incorporation of nanoparticles can increase the strain in comparison to pure PP fibers. In addition to the mechanical analysis, the crystallization and the formation of the fiber structure was evaluated. It was shown that the nanoparticles have a clear impact on the formation of the crystals and the alignment of the macromolecules. Also, it was revealed that the nanoclay is aligned in the fiber direction in the spinning process and no further drawing is needed for this alignment.
