Abstract
PET fiber-reinforced polypropylene (PP) films were successfully prepared using
unidirectional fabrics with polyethylene terephthalate (PET)/PP sea-island fibers to improve
the physical properties of the PP film. The PP part of the PET/PP sea-island fiber was converted
to a film using a hot press, and the PET fiber part, which had a higher melting temperature
than the PP part, reinforced the structure. The internal structure and physical
properties of the films were evaluated using scanning electron microscopy, a tensile
strength test, and a tearing strength test. It is shown that the physical properties of the PP
film based on unidirectional fabrics are superior to those of the film based on air-laid nonwovens.
